发明人多年来对雷公藤根、茎、叶等植物组织用酸水提取法、乙醇提取法、氯仿热提甲醇沉淀法提取的浸提物进行了杀虫谱和杀虫效果的研究，发现雷公藤浸提物对众多农业害虫和园林树木害虫具有较好的防治效果，其对害虫的作用方式有胃毒作用、触杀作用、拒食作用、熏蒸作用、麻醉作用。

It is the first time that these phenomena were observed: Two nuclei are surrounded by plasma and locate at the central of the female gametophyte and the others nuclei are positioned at the fringe of the female gametophyte; Before the pollen tube enters the female gametophyte. the nuclei in chalazal end begin splitting of plasma and form multinuclear cell.4. The pollens of Gnetumc are spherical or applanate with single aperture. The ornamentation of exine is spine. The basis part of spine is lenience and the top part of spine is tip or obtuse sphere.

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.
