Abstract
OBJECTIVE
To study the chemical constituents in the twigs and leaves of Ligustrum obtusifolium.
METHOD
Seven compounds were isolated from the ethanol extract of the twigs and leaves by polystyrene resin RA and silica gel column chromatography. The structures were identified by spectral analysis.
RESULT
Of the seven compounds isolated six were identified as luteolin, luteolin-4'-O-beta-D-glucopyranoside, (+)-pinoresinol, (+)-pinoresinol-4'-O-beta-D-glucopyranoside, (+)-medioresinol and (-)-olivil.
CONCLUSION
luteolin, luteolin-4'-O-beta-D-glucopyranoside, (+)-pinoresinol, (+)-medioresionnol and (-)-olivil were isolated from this plant for the first time.
