The isolated compounds were evaluated for their antiinflammatory activities on the inhibition of lipopolysaccharide-induced nitric oxide production in macrophage RAW 264.7 cells and the diarylheptanoids 1a and 1b mixture and 14 exhibited potent inhibitory activity.Mahidol UniversityAgricultural and Biological SciencesArticleSCOPUS
