[Studies on the chemical constituents of seed from Nigella glandulifera].
Seven compounds were isolated from the seed of Nigella glandulifera. Their structures were identified as kaempferol-3-O-beta-D-galactopyranosyl (1-->3)-beta-D-glucopyranosyl(1-->3)-beta-D-glucopyranoside (N-I), 2-O-[alpha-D-galactopyranosyl (1-->4)-beta-D-glucopyranosyl]-beta-D-fructofuranoside (N-II), N, N-dimethyl-1, 2-dimethoxy-10, 11-dihydric aporphine quaternary ammonium chloride (N-III), 3-O-[beta-D-xylo-pyranosyl (1-->3)-alpha-L-rhamnopyranosyl (1-->2)-alpha-L-arabinopyranosyl]- 28-O -[alpha-L-rhamnopyranosyl (1-->4)-beta-D-glucopyranosyl (1-->6) beta-D-glucopyranosyl]-hederagenin (N-IV), sucrose(N-V), beta-sitosterol(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 analysed. It is the first time for the study on chemical constituents of the seed of Nigella glandulifera.
