华麻花头根中的蜕皮甾酮类成分

Ecdysteroids from the Roots of Serratula chinensis

摘要:

从华麻花头(SerratulachinensisS.Moore)根中分得7种蜕皮甾酮类化合物,经光谱分析和化学方法,分别鉴定为:20-羟基蜕皮松(1),podecdysoneC(2),3-氧-乙酰基-20-羟基蜕皮松(3),20-羟基蜕皮松-20,22-缩丁醛(4),shidasterone(5),atrotosteroneC(6)和carthamosterone(7),其中20-羟基蜕皮松-20,22-缩丁醛为一新的化合物。

Abstract:

Seven ecdysteroids,20-hydroxyecdysone(1),podecdysone C(2),3-O-acetyl-20-hydroxyecdysone(3),20-hydroxyecdysone-20,22-butylidene acetal(4),shidasterone(5),atrotosterone C(6)and carthamosterone(7),were isolated from the roots of Serratula chinensis S.Moore.All compounds except compound1were isolated from this plant for the first time,and compound4was found to be a new ecdys-teroid.
