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

Chai-Hu is one of the most popular Chinese traditional drugs used ever since the ancient time and is prescribed principally in the treatment of fevers and influenza. In this article, the authors report a new species, Bupleurum luxieuse Y. Li et S. L. Pan which was discovered in Yunnan Province and used as Chinese drug under the name of Chai-Hu. The morphology was analysed and preliminary phytochemical tests of B. luxiense were carried out. The thin layer chromatograms and gas chromatograms of the essential oil and the qualitative analysis of the saikosaponin of this new species are similar to those of Bupleurum chinense DC., a standard material medica of Chai-Hu. Moreover, the roots of B. luxiense is discovered to have saikoside 2 times more than B. chinense. The results suggest that the new species be used as a substitute of high quality for Chai-Hu.

十六种晋产北柴胡柴胡皂苷含量分析

本实验分别以高效液相色谱法和分光光度法测定了山西省十三个产地的16种北柴胡中柴胡皂苷a、d及柴胡总皂苷的含量.结果表明,在16种晋产北柴胡中,柴胡皂苷a的质量分数为0.038％～0.369％,柴胡皂苷d的质量分数为0.036％～0.681％,柴胡总皂苷的质量分数为0.354％～3.949％;12种晋产北柴胡中的柴胡皂苷a、10种中的柴胡皂苷d和13种中的柴胡总皂苷含量分别超过了0.1％、0.2％和1.0％.     

Localization and dynamic change of saikosaponin in root of Bupleurum chinense

Anatomical,histochemlcal and phytochemical methods were used to investigate the structure,the localization and content changes of total saikosaponin and saikosaponin-a of the roots of Bupleurum chinense DC.at different developmental stages.Results showed that saikosaponin was mainly distributed in pericycle and primary phloem in the young root;but In the mature root,it was mainly distributed in vascular camblum and secondary phloem.During the whole growth period from the pre-blossom,blossom,fruit,and fruit mature periods until the pre-withering period,it was in the fruit mature period that both the total saikosaponin content and the saikosaponin-a content reached the highest level.So the last 20 d of October was considered as the right collecting season for the drug of B.chinense.In addition,the quality of 1-year-old drug was better than that of 2-year-old drug due to its higher saikosaponin content.On the other hand,judging from the external characteristics of the drug,the one with an acerose taproot and more lateral roots was of better quality.The results offered theoretical bases for selecting medicinal material of high quality and determining the most appropriate harvesting stage and part of B.chinense.

Revision on Cephalostachyum Munro (Poaceae: Bambusoideae) in China

Species of Cephalostachyum Munro (Poaceae: Bambusoideae) from China are distributed in Yunnan and Tibet, mainly in Yunnan. In this paper, we discussed species of Cephalostachyum and compiled a key to species from China, based on recent studies on micromorphological characters of leaf epidermis and molecular phylogenetics of paleotropical woody bamboos. There is a total of seven species of Cephalostachyum distributed in China, all in Yunnan: Cchinense (Rendle) DZ. Li et HQ. Yang, Cfuchsianum Gamble et Hook. f., Cmannii (Gamble) Stapleton et DZ. Li, Cpallidum Munro, Cpingbianense (Hsueh et YM. Yang ex Yi et al.) DZ. Li et HQ. Yang, Csanguineum (WP. Zhang) DZ. Li et HQ. Yang and Cscandens Bor. Leptocanna Chia et HL. Fung and Cvirulentum YM Yang et F. Du are synonyms of Cephalostachyum Munro and Cfuchsianum Gamble et Hook. f. respectively. On the other hand, Cpergracile Munro and Cvirgatum (Munro) Kurz are morphologically closer to Schizostachyum Nees than to Cephalostachyum, and they should be treated as members of Schizostachyum. This paper is of significance to a worldwide revision of Cephalostachyum.

Taxonomical history and revision of Paeonia sect. Moutan (Paeoniaceae)

The taxonomical history of the woody group(peonies) in the genus Paeonia is reviewed in the present paper. The group is endemic to China, but Paeonia suffruticosa is commonly cultivated throughout the north temperate region and has long been known as “the King of Flowers” in China. However, the taxonomy of the group had been neglected before the 1990' s. Since 1990, a number of new species and subspecies have been published. With the support from the National Geographic Society, the senior author of the present paper and his coworkers have made expeditions to all parts of the distribution area of the group, visited all the type localities and sampled a total of 64 populations. Based on the character analysis and examination of the type specimens or photos, each taxon is reviewed with its name checked nomenclaturally, and finally the taxonomy of the whole group is revised. As a result, eight species, three of which each contains two subspecies, are recognized. They are Paeonia suffruticosa Andrews subsp. suffruticosa and subsp. yinpingmudan D. Y. Hong, K. Y. Pan et Z. W. Xie, P. jishanensis T. Hong et W. Z. Zhao, P. qiui Y. L. Pei et D. Y. Hong, P. ostii T. Hong et J. X. Zhang, P. rockii (S. G. Haw et L. A. Lauener )T. Hong et J. J. Li subsp. rockii and subsp. taibaishanica D. Y. Hong, P. decomposita Hand.-Mazz. Subsp. decomposita and subsp. rotundiloba D. Y. Hong, P. delavayi Franeh. and P. ludlowii (Stern et Taylor)D. Y. Hong. P. baokangensis Z. L. Dai et T. Hong and P. yananensis T. Hong et M. R. Li are considered as hybrids between P. rockii and P. qiui and between P. rockii and P. jishanensis respectively. In addition, the reduction of a number of names recently published to synonyms is explained.
