In this work, the effects of culture factors ( MET, IBA, culture medium and culturing in dark) on root formation were studied in tissue culture of Celastrus angulatus. The results showed that the root induction was significantly affected by duration of culture in dark, while other factors were least effective.

探讨了培养因子对诱导苦皮藤试管苗生根的作用，采用正交试验设计法测试了苦皮藤生根关键因素多效唑、吲哚丁酸、暗培养及培养基中盐浓度的效应。

The primary studies on insecticidical and fungicidical components of endophytic fungus in Celastrus angulatus have been carried out from September, 2000 to June, 2002.The results are as follows: Taking PDA and Czapek as separating culture medium, 39 strains of endophytic fungus were separated from the bark, phloem and xylem of the root and twig of Celastrus angulatus.

作者于2000年9月至2002年6月对杀虫植物苦皮藤中内生真菌的杀虫杀菌活性物质进行了初步的研究，取得了以下结果：采用常规的内生真菌分离方法，以马铃薯葡萄糖培养基、Czapek培养基为分离用培养基，从苦皮藤根和侧枝的表皮、韧皮部和木质部中分离得到39株内生真菌。

Its insecticidal active ingredients are sesquiterpenoid polyol esters with a dihydroagarofuran structure. These compounds are stable to light, heat, and pH, and exert a narcotic and toxic poisoning action. Celastrus angulatus contains a plant-origin insecticide with a unique mechanism of action. Celangulins, a 0.2% emulsifiable concentrate has already been developed for insect control.

是我国广泛分布的一种杀虫植物，其杀虫有效成分基本上均是以二氢沉香呋喃为骨架的多元酯类化合物，对光、热和pH值均稳定，对害虫主要表现为麻醉和毒杀作用，苦皮藤是一类作用机理独特的植物源杀虫剂，在其实际杀虫的应用上，已经开发出了0.2%苦皮藤素乳油。

Fourier Transform Infrared and Horizontal Attenuated Total Reflectance techniques were used to obtain the FTIR of semen cuscutae (the seed from Cuscuta chinensis lam) and Japanese dodder seed (the seed from Cuscuta japonica Choisy). The similar features between the semen cuscutae and Japanese dodder seed are extracted by continuous wavelet transform.

采用水平衰减全反射傅里叶变换红外光谱法测定了同属种子植物中药材菟丝子及金灯藤的FTIR，运用基于连续小波多分辨率分析法对吸收较为相似的菟丝子及金灯藤的FTIR进行特征提取。
