Identification of Castasterone, 6-Deoxocastasterone, and Typhasterol in the Pollen of Robinia pseudo-acacia L.

Abstract

From the pollen of Robinia pseudo-acacia L., bioactive substances in the rice lamina inclination test were extracted and purified by several chromatographic steps to give highly purified fractions. They were derivatized and then analyzed by GC-MS, resulting in identification of castasterone, 6-deoxocastasterone, and typhasterol.
