To investigate the chemical constituents from the twigs of Piper hancei.
The chemical constituents were isolated and purified by means of chromatographic techniques including silica gel,Sephadex LH-20 and preparative RP-HPLC. Their structures were elucidated on the basis of physicochemical properties and spectral analysis.
Eight compounds were isolated and identified as 4-allylpyrocatechol(I), piperlonguminine(II), d-sesamin(Ill), beta-sitosterol (IV), pellitorine(V), piperolactam A(VI) and piperolactam D(VII), respectively.
Compound I, III, VI and VII are isolated from Piper hancei for the first time.
研究毛蒌嫩枝的化学成分。
采用硅胶、葡聚糖凝胶LH - 20及制备型反相高效液相色谱等色谱技术对化学成分进行分离纯化。根据理化性质和光谱分析确定其结构。
分离鉴定出8个化合物，分别为4 - 烯丙基邻苯二酚（I）、荜茇明宁碱（II）、d - 芝麻素（III）、β - 谷甾醇（IV）、胡椒碱（V）、胡椒酰胺A（VI）和胡椒酰胺D（VII）。
化合物I、III、VI和VII为首次从毛蒌中分离得到。
