Abstract:
OBJECTIVETo study the chemical constituents of Dendrobium gratiosissimum.
METHODThe constituents were isolated and purified by silica gel, Sephadex LH-20 colum chromatography, and the structures were identified by physicochemical properties and spectral data.
RESULTNine compounds were obtained as: 3,5,4'-trihydroxybibenzyl (1), 3,4'-dihydroxy-5-methoxybibenzyl (2), 3,4-dihydroxy-4', 5-dimethoxybibenzyl (3), apigenin (4), p-hydroxybenzaldehyde (5), defuscin (6), n-octacostyl ferulate (7), beta-sitosterol (8) and daucosterol (9).
CONCLUSIONAll these compounds were obtained from this plant for the first time, and compounds 2, 4 and 5 were isolated firstly from this genus.
