The Structure of Parvifolinoic Acid Isolated from Leaves of Isodon parvifolia

Guo Yue-wei,Cheng Pei-yuan and Xu Guang-yi   

Abstract: Eleven compounds were isolated from the leaves of lsodon parvifolia (Batalin) Hara. On the basis of spectral analysis and chemical methods, crystal Ⅳ was identified as a new compound, named parvifolinoic acid; Crystals Ⅴ–Ⅹ were identified as stearic acid (Ⅴ), β-sito- sterol (Ⅵ), daucosterol (Ⅶ), olenoic acid (Ⅷ), ursoric acid (Ⅸ), 2α-hydroxy-ursoric acid (Ⅹ) respectively. Primary pharmacology tests showed that crystal Ⅳ had inhibitory effect against QGY-7703.

Key words: parvifolinoic acid, lsodon parvifolia, lsodon
