从垂穗石松Palhinheacernua中分得6个化合物，经理化常数测定和光谱分析鉴定Ⅰ为羟基垂石松碱，Ⅱ为千层塔萜烯二醇，Ⅱ为21－表千层塔萜二醇，Ⅳ为垂石松酸甲，Ⅴ为伸筋草萜三醇，Ⅵ为16－氧代伸筋草萜三醇。
Six compounds were obtained from P. rhizomatis Palhinheacernua. The determination of the managerial constants and the spectral analysis identified I as hydroxyperdinitsone, II as the mesoterpene diol, and II as the 21-thm layer of quinonediol IV. It is clindamylic acid A, V is triamcinolonetriol, and VI is 16-oxoglutentrione.
