Abstract:Nine compounds were isolated from the Periploca forrestii Schltr. by chromatographic techniques. On the basis of physico-chemical properties and spectral data, they were identified as α-amyrin (Ⅰ), α-amyrin acetate (Ⅱ), 27-hydroxy-α-amyrin (Ⅲ), β-amyrin (Ⅳ), β-amyrin acetate (Ⅴ), ursolic acid (Ⅵ), β-sitosterol (Ⅶ), dauricine (Ⅷ), emodin (Ⅸ). Compounds Ⅰ, Ⅲ, Ⅳ, Ⅴ were isolated from this plant for the first time.
