从石竹中分离得到7个外皮甾体，其中包括3个新化合物1-3，并结合化学衍生化技术对其结构和构型进行了鉴定。4种已知化合物蜕皮酮(4)、20-羟基蜕皮酮(5)、2-脱氧-20-羟基蜕皮酮-3- o - β -d -葡萄糖吡喃苷(6)和20-羟基蜕皮酮-3- o - β -d -葡萄糖吡喃苷(7)为首次从该植物中分离得到。
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.
