Studies on resource of Ephedra sinica and the related Ephedra plants in Eurasia and evaluation of their quality as the crude drug.

麻黄属植物的地上部分是世界范围内的主要药材。其中，E. Sinica是目前日本和中国市场上最常用的原料药。E. dahurica和E. distachya与E. sinica。而E. dahurica分布于俄罗斯远东的有限地区，无药用记录，与E. sinica。我检测了E. 2006年在东西伯利亚的Bryatia采集的dahurica样品中，E.金泽大学植物标本馆的《中国植物标本券》是三景教授在中国和蒙古收集的。我还检查了2008年在阿尔卑斯山收集的E.distachya样本以及Freitag教授存放的卡塞尔大学的凭证。揭示了E.麻黄属植物，并将其贬为生药。

The aerial part of Ephedra plants is a staple crude drug worldwide. Among them, E. sinica iscurrently the most commonly used crude drug in the Japanese and Chinese market. E. dahuricaand E. distachya are believed to be closely related to E. sinica. However, E. dahurica,distributed in limited area of Far East Russia, has no record of medicinal usage, neither clearevidence on the relationship with E. sinica. I examined DNA sequences of E. dahurica samples,which I had collected in Bryatia, East Siberia, in 2006, E. sinica vouchers of the Herbaria ofKanazawa University collected in China and Mongolia by Prof Mikage. I also examined E.distachya samples collected in 2008 in Alps as well as vouchers of Kassel University depositedby Prof Freitag. I revealed the phylogenic relationship of E. sinica-relating Ephedra plants, andevaluated them as the crude drug.
