摘要: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 ofSerratula chinensis S. Moore. All compounds except compound 1 were isolatedfrom this plant for the first time, and compound 4 was found to be a new ecdysteroid.%从华麻花头(Serratula chinensis S.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),podecdysone C(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),atrotosterone C(6)和carthamosterone(7),其中20-羟基蜕皮松-20,22-缩丁醛为一新的化合物.
