Four phytoecdysteroids that have only 19 or 21 carbons, named 11alpha-hydroxyrubrosterone (1), dihydroxyrubrosterone (2), rubrosterone (3) and poststerone (4), were isolated from the whole plant of Cyanotis arachnoidea C.B. Clarke. Among them, 1 was a new compound. Their structures were elucidated by spectroscopic methods.
从蛛丝毛蓝耳草（Cyanotis arachnoidea C.B. Clarke）全草中分离出四种仅含有19个或21个碳原子的植物蜕皮甾体，分别命名为11α-羟基红甾酮（1）、二羟基红甾酮（2）、红甾酮（3）和后甾酮（4）。其中，1为新化合物。通过光谱方法阐明了它们的结构。
