Two New Species of the Genus Bupleurum (Umbelliferae) from China

Bupleurum is a genus largely distributed in temperate regions of the Northern Hemisphere. In China 36 species, 17 varieties and 7 forms have hitherto been reported and most of them are used as Chinese traditional drugs under the name of Chai-Hu. Chai-Hu is one of the most popular drugs used ever since the ancient time and is prescribed principally in the treatment of fevers and influenza. In this article, the authors report two new species, B. kunmingense Y. Li et S. L. Pan and B. polyclonum Y. Li et S. L. Pan which were discovered in Yunnan Province based on morphological studies and preliminary phytochemical tests. The ultraviolet spectrums and thin layer chromatograms of the essential oil and the crude saikosaponins of the two new species are similar to those of B. chinense DC., the standard material medica of Chai-Hu. Moreover, two new saikosaponin spots located between saikosaponin a and c in TLC were discovered in the two new species, and this could be served as a chemical evidence for identification purpose. In the histochemistry examination, the reaction of saikosaponin with color developing agent in parenchyma of the roots of the two new species is obviously more significant than that of B. chinense DC. and this phenomenon has also been proved to be true by TLC of the crude saikosaponin extracts of these two new species. It is suggested that the two new species be used as a substitute ofhigh quality for Chai-Hu.     

横断山区伞形科4种7个居群植物的核型研究

对横断山区伞形科棱子芹属2种植物(松潘棱子芹Pleurospermum franchetianumHemsl.和西藏棱子芹Pleurospermum hookeriC.B.Clarke var.thomsoniiC.B.Clarke)和茴芹属2种植物(异叶茴芹Pimpinella diversi-foliaDC.和锐叶茴芹Pimpinella argutaDiels)共7个居群进行体细胞染色体数目观察和核型比较分析,结果表明,棱子芹属和茴芹属植物属内种间染色体基数存在差异,其中松潘棱子芹为2n=2x=18=16sm 2st,西藏棱子芹为2n=2x=22=16m 6sm;茴芹属光果组中锐叶茴芹为2n=2x=22=22m,毛果组中异叶茴芹为2n=18=18st或2n=18=2sm 16st.松潘棱子芹、西藏棱子芹、锐叶茴芹的染色体数目和核型均为首次报道,从而为棱子芹属和茴芹属的分类和演化研究提供细胞学依据.
