    (2025-01-01) Ruampatana J.; Settachaimongkon S.; Kaewsirikool J.; Iamraksa P.; Choompoo S.; Suwimonteerabutr J.; Homyog K.; Mekboonsonglarp W.; Feyera T.; Nuntapaitoon M.; Ruampatana J.; Mahidol University
    The present study aimed to investigate the effects of probiotic Bacillus licheniformis DSMZ 28710 supplementation on sow performance, Preweaning piglet performance, and the biochemical profiles of colostrum and milk. Sixty-eight crossbred sows (Landrace (Formula presented.) Yorkshire) were allocated to either a standard lactation diet (Control; n = 35) or the Control diet supplemented with 10 g/sow/day of B. licheniformis DSMZ 28710 (Treatment; n = 33), from day 109 of gestation until day 21 of lactation. Sow and piglet performance, as well as the incidence of piglet diarrhea, were recorded. Moreover, the study investigated the changes in major chemical compositions, immunoglobulins, fatty acids, and non-volatile polar metabolites in colostrum, transient milk, and mature milk of sows. Supplementation of B. licheniformis increased piglet body weight on day 21 of lactation in old parity sows (p = 0.037). Moreover, the incidence of diarrhea was reduced in piglets suckled by sows supplemented with B. licheniformis DSMZ 28710, regardless of sow's parity or lactation stage (p < 0.05). Probiotic supplementation decreased fat content in transient milk (p = 0.026) and increased lactose content in mature milk (p = 0.011). Chemometric analysis revealed clear distinctions between the Control and Treatment group in the fatty acid profiles of colostrum, transient milk, and mature milk, while notable differences in non-volatile polar metabolite profiles were observed specifically in mature milk. In conclusion, supplementation with B. licheniformis DSMZ 28710 reduced the incidence of diarrhea in piglets, increased body weight of the piglets in old parity sows and altered the biomolecular profiles in colostrum, transit milk, and mature milk of the sows.

    (2024-07-01) Ruampatana J.; Suwimonteerabutr J.; Homyog K.; Mekboonsonglarp W.; Kanjanavaikoon K.; der Veken W.V.; Poonyachoti S.; Feyera T.; Settachaimongkon S.; Nuntapaitoon M.; Ruampatana J.; Mahidol University
    The present study aimed to investigate the impact of Clostridium butyricum probiotic feed additive on sow and piglet performances, together with alterations in the lipidomic and metabolomic profiles of sow milk. Sixty-four Landrace × Yorkshire crossbred sows and 794 piglets were included. Sows were divided into two groups; i.e., (i) conventional gestation diet (control; n = 35) and (ii) conventional diet added with 10 g/sow/day of probiotic C. butyricum spores (treatment; n = 29) from one week before the estimated farrowing day until weaning (29.6 ± 4.8 days). The sow and piglet performances and incidence of piglet diarrhea were recorded. Changes in gross chemical composition, fatty acid and non-volatile polar metabolite profiles of sow colostrum, transient milk and mature milk were evaluated. The results showed that relative backfat loss in the treatment group (−2.3%) was significantly lower than in control group (11.6%), especially in primiparous sows (p = 0.019). The application of C. butyricum probiotics in sows significantly reduced the incidence of diarrhea in piglets (p < 0.001) but no other effect on piglet performance was found. Lipidomic and metabolomic analyses revealed variations in sow colostrum and milk biomolecular profiles, with indicative compounds significantly altered by feeding with the C. butyricum probiotics. In conclusion, the use of C. butyricum probiotics in sows may improve sow body condition and reduce diarrhea incidence in piglets, with underlying changes in milk composition that warrant further investigation. These findings support the potential of C. butyricum as a beneficial feed additive in swine production.

    Combined effects of UV-C pretreatment and subsequent pasteurization on the alteration in bovine milk metabolomic profile
    (2026-01-01) Settachaimongkon S.; Makararpong D.; Koeipudsa C.; Denchai S.; Homyog K.; Mekboonsonglarp W.; Assatarakul K.; Settachaimongkon S.; Mahidol University
    This study investigated the impact of ultraviolet-C (UV-C) irradiation in combination with pasteurization on the variation in bovine milk metabolite composition. Raw milk was pretreated with UV-C (253 nm) at two different doses (0.95 and 2.20 J L−1), followed by pasteurization, to assess how exposure intensity and processing sequence influence metabolite composition. A total of 45 non-volatile metabolites were identified using1H NMR metabolomics approach. Multivariate analysis revealed distinct metabolome patterns among untreated, different UV-C-treated, and pasteurized milk samples, highlighting treatment-dependent alterations. The higher UV-C irradiation dose (2.20 J L−1) resulted in more pronounced metabolite losses in raw milk, attributable to intensified photochemical degradation. Although the combination of UV-C and pasteurization produced cumulative metabolite reductions, notably, UV-C treatment at the lower dose (0.95 J L−1) appeared to sensitize milk metabolites to subsequent heat-induced degradation. These findings provide insights into how combined UV-C and thermal treatments impact milk metabolomic profile, emphasizing the necessity for further process optimization.

    Dynamics of fatty acid and non-volatile polar metabolite profiles in colostrum and milk depending on the lactation stage and parity number of sows
    (2023-12-01) Settachaimongkon S.; Homyog K.; Mekboonsonglarp W.; Soonoue P.; Lerdamnuaylarp T.; Prayoonpeeraput P.; Theil P.K.; Nuntapaitoon M.; Mahidol University
    The objective of this study was to investigate the impact of lactation stage and parity number on fatty acid and non-volatile polar metabolite profiles in sow colostrum and milk using a metabolomics approach. A total number of 63 colostrum, transient and mature milk were collected from primiparous and multiparous Landrace × Yorkshire crossbred sows. Macrochemical, fatty acid and non-volatile polar metabolite compositions of samples were analyzed using infrared spectrometry, gas chromatography coupled with mass-spectrometry and proton nuclear magnetic resonance spectroscopy, respectively. Univariate and multivariate statistical analysis demonstrated significant impacts of lactation stage and parity number on colostrum and milk compositions. Chemometric analysis revealed significant influences of sow parity on the distinction in fatty acid profiles of mature milk while the distinction in non-volatile polar metabolite profiles was more evident in colostrum. Alterations in the concentration of linoleic (C18:2n6), lignoceric (C24:0), behenic (C22:0), caprylic (C8:0) and myristoleic (C14:1) acid together with those of creatine, creatinine phosphate, glutamate and glycolate were statistically suggested to be mainly affected by sow parity number. Variations in the concentration of these compounds reflected the physiological function of sow mammary gland influenced. This information could be applied for feed and feeding strategies in lactating sows and improving lactating performances.

    Influence of Different Types, Utilization Times, and Volumes of Aging Barrels on the Metabolite Profile of Red Wine Revealed by 1H-NMR Metabolomics Approach
    (2023-09-01) Denchai S.; Sasomsin S.; Prakitchaiwattana C.; Phuenpong T.; Homyog K.; Mekboonsonglarp W.; Settachaimongkon S.; Mahidol University
    It is well recognized that the aging process is a critical step in winemaking because it induces substantial chemical changes linked to the organoleptic properties and stability of the finished wines. Therefore, this study aimed to investigate the influence of different types, utilization times, and volumes of aging barrels on the metabolite profile of red wines, produced from Thai-grown Shiraz grapes, using a non-targeted proton nuclear magnetic resonance (1H-NMR) metabolomics approach. As a result, 37 non-volatile polar metabolites including alcohols, amino acids, organic acids, carbohydrates and low-molecular-weight phenolics were identified. Chemometric analysis allowed the discrimination of wine metabolite profiles associated with different types of aging containers (oak barrels vs. stainless-steel tanks), as well as the utilization times (2, 6 and >10 years old) and volumes (225, 500 and 2000 L) of the wooden barrels employed. Significant variations in the concentration of formate, fumarate, pyruvate, succinate, citrate, gallate, acetate, tyrosine, phenylalanine, histidine, γ-aminobutyrate, methionine and choline were statistically suggested as indicators accountable for the discrimination of samples aged under different conditions. These feature biomarkers could be applied to manipulate the use of aging containers to achieve the desired wine maturation profiles.

    Isolation and Identification of Dihydrophenanthrene Derivatives from Dendrobium virgineum with Protective Effects against Hydrogen-Peroxide-Induced Oxidative Stress of Human Retinal Pigment Epithelium ARPE-19 Cells
    (2023-03-01) Panuthai P.; Phumsuay R.; Muangnoi C.; Maitreesophone P.; Kongkatitham V.; Mekboonsonglarp W.; Rojsitthisak P.; Likhitwitayawuid K.; Sritularak B.; Mahidol University
    Oxidative stress is a significant factor in the development of age-related macular degeneration (AMD), which results from cell damage, dysfunction, and death in the retinal pigmented epithelium (RPE). The use of natural compounds with antioxidant properties to protect RPE cells from oxidative stress has been explored in Dendrobium, a genus of orchid plants belonging to the family Orchidaceae. Two new compounds and seven known compounds from the MeOH extract of the whole plant of Dendrobium virgineum were successfully isolated and structurally characterized. Out of all the compounds isolated, 2-methoxy-9,10-dihydrophenanthrene-4,5-diol (3) showed the highest protective effect against hydrogen peroxide (H2O2)-induced oxidative stress in human retinal pigment epithelial (ARPE-19) cells. Therefore, it was selected to evaluate its protective effect and mechanism on oxidative-stress-induced ARPE-19 cells. Cells were pre-treated with compound 3 at 25, 50, and 100 µg/mL for 24 h and then induced with 400 µM H2O2 for 1 h. The results demonstrated that compound 3 significantly (p < 0.05) increased cell viability by 10–35%, decreased ROS production by 10–30%, and reduced phosphorylation of p38, ERK1/2, and SAPK/JNK by 20–70% in a dose-dependent manner without toxicity. Furthermore, compound 3 significantly (p < 0.05) modulated the expression of apoptosis pathway proteins (cytochrome c, Bax and Bcl-2) by 20–80%, and enhanced SOD, CAT, and GPX activities, and GSH levels in a dose-dependent manner. These results suggest that compound 3 protects ARPE-19 cells against oxidative stress through MAPKs and apoptosis pathways, including the antioxidant system. Thus, compound 3 could be considered as an antioxidant agent for preventing AMD development by protecting RPE cells from oxidative stress and maintaining the retina. These findings open up new possibilities for the use of natural compounds in the treatment of AMD and other oxidative-stress-related conditions.

    Metabolomic and lipidomic insights into the impact of Euglena gracilis-derived β-glucan supplementation on sow colostrum and milk composition
    (2025-01-01) Ruampatana J.; Feyera T.; Yamsrikaew U.; Juarjan M.; Homyog K.; Mekboonsonglarp W.; Settachaimongkon S.; Nuntapaitoon M.; Ruampatana J.; Mahidol University
    Euglena gracilis, an algae-derived source of β-glucan, exhibits prebiotic activity that enhances colostrum quality and improves growth, though the underlying mechanisms remain unclear. This study investigates the effects of E. gracilis supplementation during late gestation and lactation on sow colostrum and milk biomolecular profiles. Sixty-one crossbred sows (Landrace × Yorkshire) were assigned to a standard diet (CON; n = 30) or the CON diet supplemented with 1 g/sow/day of E. gracilis (TRT; n = 31) from day 85 of gestation until day 21 of lactation. Sow performance, including litter size and weight, was recorded from birth to day 21 of age. Colostrum samples (n = 20; 10 sows/group) were collected within 1 h of farrowing, and milk samples were collected from the same sows on days 3 and 10 of lactation to assess alterations in non-volatile polar metabolites (NVM), fatty acids (FA), and associated metabolic pathways. On average, the litter size at birth was 14.2 ± 2.5 piglets/litter, with no effect of dietary treatment from birth to day 21 of lactation (P > 0.05). However, piglets suckled by TRT sows tended to have higher average daily gain from birth to day 21 of age than those suckled CON sows (191.0 ± 6.7 vs. 173.6 ± 6.8 g/day, P = 0.073). Chemometric analysis revealed distinct NVM and FA profiles between the groups, particularly in the colostrum. Although E. gracilis supplementation influenced the contents of multiple metabolites, focus has been given to those that have direct impact on piglet development, including increased colostrum leucine (P = 0.001), threonine (P < 0.001), and N-acetylglucosamine (P = 0.002), enhancing colostrum quality and immunomodulatory potential. Elevated colostrum gamma-linolenic acid (P = 0.047) and arachidonic acid (P = 0.019) levels suggested enhanced immune development. Pathways associated with amino sugars and nucleotide sugars and glucose-related metabolism in colostrum were also modulated. These findings suggest E. gracilis-derived β-glucan as a potential dietary supplement for enhancing sow colostrum quality and piglet growth.

    Regulatory effects of specialized metabolites from Dendrobium albosanguineum on lipid metabolism and adipocyte differentiation
    (2025-12-01) Wuttiin J.; Nuntawong P.; Khine H.E.E.; Sungthong R.; Kitisripanya T.; Thant M.T.; Chaotham C.; Mekboonsonglarp W.; Likhitwitayawuid K.; Sritularak B.; Wuttiin J.; Mahidol University
    The rising global incidence of obesity underscores the urgent demand for effective therapeutic interventions. Natural products have emerged as promising alternatives; however, identifying candidates that effectively target the complex mechanisms underlying obesity remains a critical challenge. In this study, the specialized metabolites of Dendrobium albosanguineum were investigated for their anti-obesity potential. Methanolic extraction was performed on the entire plant, followed by systematic fractionation and compound elucidation using mass spectrometry and nuclear magnetic resonance spectroscopy. A set of in vitro colorimetric assays was employed to assess pancreatic lipase inhibition, cytotoxicity, intracellular lipid storage, triglyceride content, and glycerol release in murine (3T3-L1) and/or human (PCS-210-010) adipocyte models. In addition, flow cytometry, western blotting analysis, and RT-qPCR were used to evaluate the effects of a chosen metabolite on cell cycle progression and the expression of adipogenesis-related genes and proteins. Eight metabolites were isolated, including bibenzyls (moscatilin, chrysotoxine), lignans (syringaresinol, foliachinenoside C), a sterol (daucosterol), a phenylpropanoid (n-octacosyl-trans-p-coumarate), and flavonoids (rhoifolin, kaempferol-3-O-(2″,6″-dirhamnosyl)glucoside). Among them, foliachinenoside C exhibited the most potent activity, with 94.77 ± 0.85% inhibition of pancreatic lipase (IC50 = 40.73 ± 0.74 µM). It significantly reduced triglyceride levels and promoted glycerol release in both murine and human adipocytes. Mechanistically, foliachinenoside C induced cell cycle arrest at the G0 phase in 3T3-L1 cells and downregulated key adipogenic transcription factors (PPARγ, C/EBPα, SREBP1c) and lipogenic proteins (FAS, PLIN1, LPL, ADPN, FABP4). Moreover, it modulated the AKT/GSK3β and AMPK-ACC signaling pathways, collectively suppressing adipocyte differentiation. These findings position foliachinenoside C as a promising plant-derived compound for obesity pharmacotherapy, warranting further investigation to facilitate its clinical development.

    Sulfated polysaccharides from Caulerpa lentillifera: Optimizing the process of extraction, structural characteristics, antioxidant capabilities, and anti-glycation properties
    (2024-01-30) Tesvichian S.; Sangtanoo P.; Srimongkol P.; Saisavoey T.; Buakeaw A.; Puthong S.; Thitiprasert S.; Mekboonsonglarp W.; Liangsakul J.; Sopon A.; Prawatborisut M.; Reamtong O.; Karnchanatat A.; Tesvichian S.; Mahidol University
    The polysaccharides found in Caulerpa lentillifera (sea grape algae) are potentially an important bioactive resource. This study makes use of RSM (response surface methodology) to determine the optimal conditions for the extraction of valuable SGP (sea grape polysaccharides). The findings indicated that a water/raw material ratio of 10:1 mL/g, temperature of 90 °C, and extraction time of 45 min would maximize the yield, with experimentation achieving a yield of 21.576 %. After undergoing purification through DEAE-52 cellulose and Sephacryl S-100 column chromatography, three distinct fractions were obtained, namely SGP11, SGP21, and SGP31, each possessing average molecular weights of 38.24 kDa, 30.13 kDa, and 30.65 kDa, respectively. Following characterization, the fractions were shown to comprise glucose, galacturonic acid, xylose, and mannose, while the sulfate content was in the range of 12.2–21.8 %. Using Fourier transform infrared spectroscopy (FT-IR) it was possible to confirm with absolute certainty the sulfate polysaccharide attributes of SGP11, SGP21, and SGP31. NMR (nuclear magnetic resonance) findings made it clear that SGP11 exhibited α-glycosidic configurations, while the configurations of SGP21 and SGP31 were instead β-glycosidic. The in vitro antioxidant assays which were conducted revealed that each of the fractions was able to demonstrate detectable scavenging activity against 1,1-diphenyl-2-picrylhydrazyl (DPPH) radicals and 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical cations. All fractions were also found to exhibit the capacity to scavenge NO radicals in a dose-dependent manner. SGP11, SGP21, and SGP31 were also able to display cellular antioxidant activity (CAA) against the human adenocarcinoma colon (Caco-2) cell line when oxidative damage was induced. The concentration levels were found to govern the extent of such activity. Moreover, purified SGP were found to exert strong inhibitory effects upon glycation, with the responses dependent upon dosage, thus confirming the potential for SGP to find a role as a natural resource for the production of polysaccharide-based antioxidant drugs, or products to promote improved health.
