Chemical constituents from Scilla scilloides.[Reference:
WebLink]
To study the chemical constituents from Scilla scilloides.
METHODS AND RESULTS:
The chemical constituents were isolated and purified by column chromatography and their structures were identified by spectral data. Eighteen compounds were isolated from S. scilloides. Their structures were identified as scillascillin(1), 2-hydroxy-7-O-methylscillascillin(2), 4′-demethyleucomin(3), 5-hydroxy-7-methoxy-3-(4-hydroxybenzylidene) chroman-4-one(4), 4′-demethyl-3, 9-dihydroeucomin(5), 3′-hydroxy-3, 9-dihydroeucomin(6), 8-O-Demethyl-7-O-methyl-3,9-dihydropunctatin(7), apigenin(8), luteolin(9), chrysoeriol(10), 3-dehydro-15-deoxoeucosterol(11), 15-deoxoeucosterol(12), 4-allylpyrocatechol(13), norlichexanthone(14), drimiopsin C(15), 6-feruloylcatalpol(16), catalposide(17), and specioside(18).
CONCLUSIONS:
Iridoids(16—18) are isolated from the genus Scilla L. for the first time. Compounds 4, 7—10, and 13—18 are isolated from the plants of this genus for the first time.
