摘　　要：目的 :弄清产区多元化对虫草药性品质的影响。方法 :对不同产地虫草样本的甘露醇含量进行直接比较和相互变异率分析。结果 :大宗药材川草、藏草、滇草以及泸草、灌草之间甘露醇含量的相互变异率为0 012～0.32 ,而各大宗药材内来自不同微生态环境的虫草样本之间甘露醇含量的相互变异率为0 037～1 36。结论 :虫草甘露醇含量受物种多样性和微生态环境的影响 。OBJECTIVE:To gain clear idea of influence of multiorigins of Cordyc ep s on quality and nature of this drug.METHODS:The mannitol contents in the Cordy ceps samples collected from different growing areas were determined and compared ,and their MDR(Mutual Different Rate)was analyzed.RESULTS:The MDRs among specim ens from Sichuan,Tibet and Yunnan were 0.012～0.32 and the MDRs among the Cordyc eps samples from different micro-ecological environment were 0.037～1.36.CONCLU SION:On the mannitol content in Cordyceps,the effect of the species diversity a nd the micro-ecological environment might exceed that of district and climate d ifference.
