Studies on chemical constituents in the seeds of Nigella glandulifera / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the chemical constituents in the seeds of Nigella glandulifera.</p><p><b>METHOD</b>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.</p><p><b>RESULT</b>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).</p><p><b>CONCLUSION</b>I, II, III, VI, VIII and IX were obtained from the plant for the first time, and I is a new compound.</p>
