[Studies on chemical constituents in the seeds of Nigella glandulifera].

To investigate the chemical constituents in the seeds of Nigella glandulifera. The chemical constituents were isolated and repeatedly purified on silica gel column. They were identified and structurally elucidated by means of physio-chemical constants and spectral analysis. Nine compounds were identified as nigellamose (I), alpha-hederin (II), 3-O-[beta-D-xylopyranosyl-(1-->3)-alpha-L-rhamnopyranosyl-(1-->2)-alpha-L-arabinpyranosyl]-hederagenin (III), sucrose (IV), stearic acid (V), 1-O-hexadecanolenin (VI), beta-sitosterol (VII), daucosterol (VIII) and p-hydroxybenzoic acid (IX). I, II, III, VI, VIII and IX were obtained from the plant for the first time, and I is a new compound.
