摘要

To study the chemical constituents of the peels collected from Citrus changshan-huyou Y. B. Chang, and further screen the bioactive components as the lead structures.These compounds were isolated by repeated flash column chromatography on silica gel and Sephadex LH-20. The structures of isolated compounds were elucidated by using IR, EIMS, and NMR analyses.One novel compound along with nine known compounds were obtained and identified as huyoujiasu(I), 3-hydroxy-4-methoxybenzoic acid(II), 3, 4-dihydroxybenzoic acid(III), fatty acid(IV), glyceride(V), 6, 7-dimethoxycoumarin(VI), 6', 7'-dihydroxybergamottin(VII), daucossterol A(VIII), daucossterol B(IX) and huyou-triterpenoid(X).One new compound, Huyoujiasu, was obtained from these peels by repeated column chromatography, and the other known compounds were isolated from this fruit for the first time as well.
