Composition of Phytosterols in the Pollen of Robinia pseudo-acacia L.

摘要

Determination was made of the compositions of phytosterols in Robinia pseudo-acacia L. pollen. The n-hexane-soluble fraction obtained from the methanol extract of the pollen was saponified and the unsaponifiable lipid was purified by preparative thin layer chromatography to afford phyto- sterols. These were derivatized as trimethylsilyl ether and analyzed by GC and GC-MS.
