Abstract: Moringa oleifera Lam (horseradish tree; tender pod or fruits) has been consumed as a vegetable and utilized as a major ingredient of healthy Thai cuisine. Previous studies have shown that M. oleifera pod extracts act as bifunctional inducers along with displaying antioxidant properties and also inhibiting skin papillomagenesis in mice. This study was aimed to determine the nutritive value, and clastogenic and anticlastogenic potentials of M. oleifera pod. The nutritive value was determined according to AOAC methods. The clastogenic and anticlastogenic potentials were determined using the in vivo erythrocyte micronucleus assay in the mouse. Eighty male mice were fed semi-purified diets containing 1.5%, 3.0% and 6.0% of ground freeze-dried boiled M. oleifera pod (bMO) for 2 weeks prior to administration of both direct-acting (mitomycin C, MMC) and indirect-acting (7, 12-dimethylbenz(a)anthracene, DMBA), clastogens. Blood samples were collected at 0, 24, 48 and 72 h, dropped on acridine orange-coated slides, and then counted for reticulocytes both with and without micronuclei by fluorescence microscopy. The nutritive value of 100 g bMO consisted of: moisture content, 8.2 g; protein, 19.2 g; fat, 3.9 g; carbohydrate (dietary fiber included), 60.5 g; dietary fiber, 37.5 g; ash, 8.1 g and energy, 354 kcal. Freeze-dried boiled M. oleifera had no clastogenic activity in the mouse while it possessed anticlastogenic activity against both direct and indirect-acting clastogens. Freeze-dried boiled M. oleifera pod at 1.5%, 3.0% and 6.0% in the diets decreased the number of micronucleated peripheral reticulocytes (MNRETs) induced by both MMC and DMBA. However, the effect was statistically significant in the dose dependent manner only in the MMC-treated group. In conclusion, the present study demonstrated that bMO has no clastogenicity and possesses anticlastogenic potential against clastogens, and particularly a direct-acting clastogen in the mouse.
