摘  要：
生测表明 ,唐古特瑞香Daphnetangutica的甲醇抽提物具有明显的拒食和胃毒活性 ,活性跟踪得到流分 9。流分 9导致菜粉蝶Pierisrapae幼虫体小 ,中肠组织细胞受到破坏 ,脂肪体呈消融状 ;对试虫生理指标的影响主要表现在降低血淋巴蛋白质含量和抑制中肠酯酶活力。

摘  要：
Bioassays of the methanol extract of Daphne tangutica , a local endemic plant in Qinghai Tebet Plateau, for insecticidal effects on the imported cabbage worm, Pieris rapae , were carried out. The results showed that the extract possessed high effects of antifeedant and stomach poison. Fraction 9 of Silica gel column chromatography proved to be the most active fraction among those partitioned from the methanol extract by bioassay driven separation. The larvae fed on leaf discs treated with fraction 9 grew slowly, and their bodies were smaller than those of the control. Histological study indicated that the tissue of midgut was destroyed and fat body became to fade out by autolysis. The preliminary physiological reaction studies showed that fraction 9 could reduce the content of protein in haemolymph and inhibited the activity of esterase in midgut significantly.
