Two minor plant ecdysteroids, 22-epi-20-hydroxyecdysone (1) and gerardiasterone (2), were isolated from Serratula tinctoria L. (Compositae). The first compound, a new natural product, was characterized by an unusual stereochemistry at C-22 (i.e., 22S). The second compound was identified as (20R,23S)-20,23-dihydroxyecdysone, a compound previously isolated from the Zooanthid Gerardia savaglia.
从染用麻花头（菊科）中分离出两种次要的植物蜕皮甾体，22-表-20-羟基蜕皮酮（1）和gerardiasterone（2）。第一种化合物是一种新的天然产物，其特征在于C-22位具有不寻常的立体化学结构（即22S）。第二种化合物被鉴定为（20R，23S）-20,23-二羟基蜕皮酮，该化合物先前已从珊瑚虫Gerardia savaglia中分离得到。
