Cytotoxic constituents of Rhododendron brachycarpum

, : Cytotoxic constituents of Rhododendron brachycarpum. Yakhak Hoeji 49(3): 244-248

From the methanol extract of Rhododendron brachycarpum four triterpenes, three phenylpropanes and a diterpene kalkaloid were isolated. Their structures were identified as glutinol (1), 3 beta-hydroxyurs-12-ene (2), beta-sitosterol (3), (E)-p-hydroxycinnamic acid hexadecylester (4), (-)-rhododendrol (5), (+)-rhododendrol (6), 3 beta-hydroxyurs-12-en-28-oic acid (7) and gray-anotoxin 1 (8) by spectroscopic methods.
