STUDIES ON THE CHEMICAL CONSTITUENTS OF SEED FROM NIGELLA GLANDULIFERA

Seven compounds were isolated from the seed of Nigella glandulifera, Theirstructures were identified as kaempferol-3-O-β-D-galactopyranosyl(1→3)-β-D-glucopyranosyl(1→3)-β-D-glucopyranoside(N-I),2-O-α-D-galactopyranosyl(1→4)-β-D-glucopyranosyl-β-D-fructofuranoside(N-II),N, N-dimethyL^-1,2-dimethoxy-10,11-dihydric aporphine quaternaryammonium chloride(N-III),3-O-β-D-xylo-pyranosyl(1→3)-α-L-rhamnopyranosyl(1→2)-α-L-arabinopyranosyl-28-O-α-L-rhamnopyranosyl(1→4)-β-D-glucopyranosyl(1→6)β-D-glucopyranosyl-hederagenin(N-IV),sucrose(N-V),5sitosterol(N-VI)and cyclolandenol(N-VII).Compounds N-I and N-II are new compounds,named nigeglanoside and nigeglanose, respectively.Apart from ten fatty acids in its oil have also been analvsed.It is the first time for the study onchemical constituents of the seed of Nigella glandulifera.
