Abstract

Seven ecdysteroids, including the three new compounds 1-3, were isolated from Sida rhombifolia L. Their structures and configurations were determined by extensive spectroscopic techniques in combination with chemical derivatization. The four known compounds--ecdysone (4), 20-hydroxyecdysone (5), 2-deoxy-20-hydroxyecdysone-3-O-beta-D-glucopyranoside (6), and 20-hydroxyecdysone-3-O-beta-D-glucopyranoside (7)--are reported for the first time from this plant.

摘要

从菱叶梵天花中分离出七种蜕皮甾体，包括三种新化合物1-3。通过广泛的光谱技术结合化学衍生化确定了它们的结构和构型。四种已知化合物——蜕皮激素（4）、20-羟基蜕皮激素（5）、2-脱氧-20-羟基蜕皮激素-3-O-β-D-吡喃葡萄糖苷（6）和20-羟基蜕皮激素-3-O-β-D-吡喃葡萄糖苷（7）——首次从该植物中报道。
