摘　　要：为促进箭叶淫羊藿Epimedium sagittatum的资源开发和合理利用,提出资源利用策略及未来研究方向。结合标本统计和野外实地调查,对箭叶淫羊藿资源分布进行系统整理。同时,结合文献查阅和课题组前期研究,对其药材质量特征,如不同采收期、不同部位、不同产地的活性成分含量差异进行综述。从资源分布来看,箭叶淫羊藿为淫羊藿属分布较广的物种,但较多腊叶标本存在鉴定错误,至少有13个其他类群被鉴定为箭叶淫羊藿。12个省和重庆市查询到分布记录,但主要分布于安徽、江西、湖南和湖北4省,且各地资源量并不丰富。从质量特征来看,不同种质的活性成分种类和含量均存在巨大差异,湖南、湖北和四川省等地部分种质优异,但整体稳定性和均一性都不理想。资源利用应根据不同种质特征区别对待。箭叶淫羊藿不同种质的质量和形态差异悬殊,且与遗传因素密切相关。未来可关注生理生态对质量的影响及机制、药材质量形成分子机制等研究方向。To promote the rational development and utilization of Epimedium sagittatum, and to propose the utilization strategies and future research suggestions. The distribution was illuminated based on the examination of herbarium specimens and our field investigation. At the same time, the quality characteristics of different harvest time, different parts and different producing areas were summarized according to the literature review and our previous researches. In terms of the distribution, E. sagittatum is a widely distributed species in Epimedium. However, there were many errors in the identification of herbarium specimens. At least 13 taxa were wrongly identified as E. sagittatum. The distribution of E. sagittatum was not as extensive as previously recorded in the literature. Although the distribution of E. sagittatum has been recorded in 12 provinces and in Chongqing Municipality, it was mainly distributed in Anhui, Jiangxi, Hunan and Hubei provinces, and the resources in each region were not abundant. In terms of quality characteristics, there were great differences in both composition and contents of the active components among different germplasm. Some of the germplasm in Hunan, Hubei and Sichuan provinces were excellent. However, the stability and homogeneity were not ideal. Therefore, the utilization of E. sagittatum should depend on the quality characteristics. It was found that there were great differences among populations and which were closely related to the genetic basis. The effect of physiological ecology on quality and its mechanism, as well as the molecular mechanism of quality formation should be paid more attention in the future.
