title: [Triterpene compounds of Ainsliaea yunnanensis].
abstract: The compounds of Ainsliaea yunnanensis were isolated and purified by various kinds of column chromatography methods and their structures were determined by spectroscopic data analysis. Twelve compounds were obtained from the petroleum ether of ethanolic extract of A. yunnanensis and elucidated as bauerenyl acetate (1), bauerenol (2), alpha-amyrin (3), psi-taraxasterol (4), beta-amyrin (5), echinocystic acid (6), multiflorenol (7), 3beta-hydroxy-olean-18-ene germanicol (8), 3beta-hexadecanoyl-12-oleanen-11-one (9), fernenol (10), fern-7-en-3beta-ol (11), and lupeol (12). All compounds were isolated from this genus for the first time except compound 1, 3, 5 and 10, and they were all isolated from this plant for the first time.
