STUDIES ON THE CHEMICAL-CONSTITUENTS OF RABDOSIA-UMBROSA VAR EXCISINFLEXA

From Rabdosia umbrosa var. excisinflexa (NAKAI) HARA were isolated two diterpenoids, five flavonoids, one aromatic compound, and two steroids. They were identified as kamebanin, kamebakaurin, pedalitin, 4'-O-methylpedalitin, genkwanin, pilloin, eupatorin, methyl caffeate, beta-sitosterol, and beta-sitosterol glucoside by the comparison of spectroscopic data with those of the authentic samples. It was clarified that both beta-sitosterol and aglycon of beta-sitosterol glucoside contained stigmasterol and campesterol by GC-MS.
