A minor C27 sterol, glaucasterol, was isolated from the soft coral Sarcophyton glaucum. Based on the spectroscopic evidence and the correlation to cholestanol and 26-nor-27-homocholestanol, its structure was proposed to be 24 epsilon,25 epsilon-24,26-cyclocholesta-5,22E-dien-3 eta-ol (1), the first example of a natural C27 sterol having a cyclopropane ring in the side chain.
一种次要的C27甾醇，即格劳卡甾醇，是从软珊瑚肉芝软珊瑚中分离出来的。基于光谱学证据以及与胆甾烷醇和26-降-27-高胆甾烷醇的关联，其结构被推测为24ε,25ε-24,26-环胆甾-5,22E-二烯-3η-醇（1），这是侧链中具有环丙烷环的天然C27甾醇的首个实例。
