Abstract:
OBJECTIVETo study the chemical constituents in seeds of Helicia nilagirica.
METHODThe ethanol extract was seperated by petroleum ether, dichloromethane, n-butanol in sequence, then isolated by silica gel column chromatography. The structures were identified and elucidated by physicochemical properties and spectral analysis.
RESULTFive compounds were isolated from the dichloromethane and n-butanol extracts, identified as p-hydroxybenzaldehyde (1), p-hydroxybenzoic acid (2), gallic acid (3), helicide (4), 4-formylpymyl-O-beta-D-glucopyranoside (5).
CONCLUSIONAll the compounds except IV were isolated from the plant for the first time. The compounds I, II and III were isolated from the genus Helicia for the first time.
