dc.description.abstract报道了有机溶剂提取法提取苦楝果实中的天然杀虫活性成分,并采用结晶法从浓缩液中成功地分离出苦楝素晶体.采用差示扫描量热仪(DSC)测定苦楝素晶体基本的理化常数──熔点.通过红外吸收光谱(IR)、紫外吸收光谱(UV)、有机质谱(ESI-MS)对苦楝素晶体进行波谱分析,其数据和文献报道的苦楝素光谱数据完全一致.
dc.description.abstractToosendanin,an insecticidal component was isolated from the fruits of Melia azadarach Linn by the ethanol extraction and the direct crystallization method.Two melting points of the crystal were obtained through differential scanning calorimetric(DSC).The melting point with water of crystallization was 186.9℃,and the melting point without water of crystallization was 236.4℃.Its structure was elucidated by spectroscopic means(ultra violet spectroscopy,electrospray ioniaztion mass spectroscopy and infrared spectroscopy).All the results of qualitative analysis agreed roughly well with the results in the related references.
