title: 6-Methylcryptoacetalide, 6-methyl-epicryptoacetalide and 6-methylcryptotanshinone from Salvia aegyptiaca.
abstract: From the whole plant of Salvia aegyptiaca, 6-methylcryptoacetalide, 6-methyl-epicryptoacetalide and 6-methylcryptotanshinone have been isolated and characterized, mainly by spectroscopic means. In addition to these novel diterpenoids, the known compounds 3beta-hydroxy-olean-12-en-28-oic acid, 3beta-hydroxy-oleana-11,13(18)-dien-28-oic acid, sitosterol-3beta-glucoside, sitosterol, stigmasterol, 5-hydroxy-7,3',4'-trimethoxyflavone and 5, 6-dihydroxy-7,3',4'-trimethoxyflavone were isolated.
