rophanthus divaricatus(Lour.)Hook et Arn.]为华南产的一种含强心甙的野生植物。朱任宏从该植物中提得具有强心作用的粉末状皂角甙,经酸水解後得到三种配基,称为羊角拗皂草水解素甲、乙、丙(strophanthiline A、B、C),其中甲素的分子式曾暂定为C25H36O4,後修改为C23H34O4。

Sarmentogenin(Ⅰa) isolated from the crude extract of Strophanthus divaracatus (Lour.)Hook et Arn,by mild acid hydrolysis was dehydrated by (a) further acidic treatment or (b) phosphorus oxychloride-pyridine dehydration via its acetate to β-anhydrosarmentogenin (Ⅲa).The latter was shown to be identical with strophanthiline A previously isolated from the same plant.
