色谱柱：μbondapak C18柱(150mm×6mm， 5μm);流动相：甲醇-乙腈-0.25mol/L磷酸溶液(9：5：10);流速：1.0ml/min;检测波长：322nm;柱温：室温。
[供试品的制备]
取本品粗粉约50g，用8倍量90%乙醇回流提取3次，每次1.5h，合并提取液，回收乙醇，得浸膏13.70g，并将其与适量经处理过的大孔吸附树脂拌匀，置于经处理过的大孔吸附树脂柱上，依次用水，20%、30%、40%、50%、60%、70%、80%、90%的乙醇冲洗，每次冲至洗脱液无色，水浴蒸干，得膏状物，分别用50%乙醇溶解，定容至50ml。按本法色谱条件进行测定。Isoimperatorin 是Angelica dahurica 根的甲醇提取物，有效抑制乙酰胆碱酯酶 (AChE)，IC50 为 74.6 μM。

During a screening program for new agrochemicals from Chinese medicinal herbs, the ethanol extract of Notopterygium incisum rhizomes is found to possess strong nematicidal activity against the two species of nematodes, Bursaphelenchus xylophilus and Meloidogyne incognita . Based on bioactivity-guided fractionation, the four constituents are isolated from the ethanol extract and identified as Columbianetin, Falcarindiol, Falcarinol, and Isoimperatorin. Isoimperatorin also has LC 50 values of 21.83 μg/mL against B. xylophilus . When using 15 min UV light treatment, falcarindiol, falcarinol, and isoimperatorin demonstrated almost five times more toxic to the southern root-knot nematodes than in dark treatment while columbianetin showed only two times more toxic. isoimperatorin has been demonstrated to possess insecticidal activity against several insects, such as the cabbage aphid ( Brevicoryne brassicae ). Isoimperatorin is identified in the active fraction of Angelica dahurica (AD) extract. Isoimperatorin is usually used as the internal standard (IS).
