As a part of our ongoing program on finding biologically active components from natural source we found three known constituents from the EtOH extract of the wheat bran. The known compounds were identified as tachioside (1), pinellic acid (2) and tryptophan (3). The structure and relative stereochemistry were determined from 1D, extensive 2D NMR, and MS techniques as well as by comparison of their data with the published values. All isolates were tested their inhibitory effects on the adipogenesis in 3T3-L1 cells. The effect of compounds from wheat bran on 3T3-L1 adipocyte differentiation were measured by Oil Red O staining. These results demonstrate that tachioside (1) and pinellic acid (2) decreased lipid content in 3T3-L1 adipocytes by inhibiting lipogenesis. These compounds had shown antiobesity activities.
