以挥发油得率、吴茱萸碱和吴茱萸次碱保留率及药材中生物碱和水溶性成分的HPLC图谱为指标，考察水蒸气蒸馏-醇提过大孔树脂柱联用工艺对保留吴茱萸有效成分的影响。

It was investigated how to increase the yield and purity of tannin, flavone and oligoprocyanidms from the root and stalk of sanguisorba, and the stability of polyphenols from sanguisorba was studied, too. The chemical constitutes of sanguisorba were analyzed, the conditions on extracting tannin, flavone and oligoprocyanidins from sanguisorba by general lixiviating process and ultrasonic wave were optimize. The flavone and oligoprocyanidins were separated from sanguisorba and purified. The stability of polyphenol from sanguisorba was studied and the chemical structure of the products was analyzed.

In addition,preliminary investigation about the correlations in the taxonomy, chemical constituents and pharmacological activities of Schisandraceae were reviewed based on references.Several correlations between the modern pharmacological researches and traditional therapeutic effects have been found.Moreover,it was also demonstrated the different pharmacological activity is related to the characteristic components of the two genera which provided the theoretical evidence to the further utilization of these plants.

同时，本文还综合了五味子科植物的传统分类学、化学成分研究、现代药理学研究及传统疗效的调查，对五味子科植物的药用植物亲缘学进行了初步探讨，发现五味子科药用植物的现代药理活性研究与传统疗效之间有很好的相关性，且很多活性也找到了相对应的物质基础，同时也向我们提示两属植物功效主治上差别的物质基础与特征性成分有关，为合理开发利用本科药用植物资源提供了理论依据。

The present paper mostly concerned was the T. piniperda which was discovered in Yunnan Province, the research advances on Pinus yunnanensis volatiles and using the volatiles to trap T. yunnanensis were reviewed, the successful experiences of using plant volatiles to monitor and control Scolytidae was briefly summarized.

针对云南纵坑切梢小蠹，综述了云南松挥发性化学成分的研究现状及利用各种挥发性成分诱集云南纵坑切梢小蠹的研究进展，同时简要介绍了国内外其他地区利用植物挥发性化学物质监测和防治小蠹类害虫的成功经验。

ResultsMany active constituents that extracted from ten batches of sample of Radix Scrophulariae (Scrophularia ningpoensis Hemsl.), which collected from Chongqing Wulong county, were evaluated by HPLC. The models of standard HPLC Fingerprint of Radix Scrophulariae were established; Taking the cinnamic acid as the reference peak, the relative time and the relative peak area ration of various characteristics peak were calculated, and the sample from Zhejiang province could be distinguished by this model and the relative peak area ratio of the characteristic components.
