Abstract

Phytochemical investigation of the sesame dregs of Sesamum indicum was conducted by open column and prep-HPLC chromatography. Two phytosterols (1 and 2) and two lignans (3 and 4) were isolated from the MeOH extracts of sesame dregs, and identified as β-sitosterol (1), daucosterol (2), sesamin (3), and sesamolin (4) by spectral analysis. Although these compounds were already isolated from sesame, it is important that they were still main phytochemical components in the sesame dregs.
