中药材是中医药事业传承和发展的基石,道地药材是我国传统优质药材的代表。由于近年来中药产业发展迅速,药材生产环节对道地性和规范性坚守不够,出现了不少质量问题。道地性和生产规范性是中药材质量属性形成的关键,强化道地性和规范生产(人工种植/养殖或野生抚育)操作,并建立与之相关的体现重要质量属性的标准,进而对中药材生产全过程进行有效控制,是保证中药材质量稳定、可控,保障中医临床用药安全有效的重要措施;同时对促进中药材生产的规模化、规范化发展,加快发展现代中药产业具有重要意义。 相似文献

论道地药材品质辨识及其与生态环境的相关性研究策略 总被引:1,自引:1,他引:0
长期以来,道地药材品质评价缺少客观明确的方法和标准,使得道地药材“道地难辨”;道地性与环境的相关性研究常因缺少客观品质指征而陷入“有目标,无指标”及“循环论证”的怪圈,难以揭示道地药材品质形成的生态环境因子.作者提出以道地药材品质评价方法和标准为突破口,从效入手,以效定质,以质论环,建立以“效-质-环”为研究路径的中药材道地性评价(道地药材品质生态学研究)思路和模式,以期为揭示影响道地药材品质形成的生态环境主导因子;建立道地药材临床合理应用剂量换算机制;阐明中药材道地性的现代科学内涵,解决制约道地药材生产发展与临床应用的关键问题提供研究基础. 相似文献

道地药材是指在特定自然条件、生态环境的地域内所产的药材,较同种药材在其他地区所产者品质佳、疗效好,在临床治疗中占有重要地位,是中药材的精髓。道地药材是古今人们评价中药品质的独特综合性指标,但关于道地药材质量评价标准和方法并没有一个完善的体系,难以阐述药材道地性的内涵。道地药材的质优效佳是实现中药材现代化的保障和依托,因此加强对道地药材的研究具有重要的现实意义。文章通过查阅文献,对道地药材的溯源、影响因素和评价方法等方面进行综述,以期为中药材道地性的研究提供理论参考,同时也为中药材的现代化发展提供科学依据。 相似文献

Objective The Chinese Pharmacopoeia (2015) includes 584 plant medicines, of which 284 also contain high quality subsets, so called “Daodi” components, where Daodi denotes superior clinical properties compared to non-Daodi counterparts despite being sourced from the same species. Commercial and clinical drivers of selection for Daodi have been described elsewhere. Our objective is to investigate the overall composition of Daodi to determine in what ways medicines with Daodi as a whole differ from the other plants of the Chinese Pharmacopoeia. A further objective is to characterise the Chinese Pharmacopoeia and Daodi in terms of the plant species including their traits and distribution.Methods We used trait analysis to identify whether Daodi species were significantly different from the remaining Chinese Pharmacopoeia plant species in any traits. We used biogeographic methods and an existing classification of Daodi into 10 regions to identify spatial patterns amongst the species. Regression and binomial analyses were used to test for over- and under-use of plant families and endemic species. Preferences for lineages were visualized using phylogenetic mapping. Results We found Daodi species (species with any Daodi subset) were more likely to be roots that are ‘hot’ or ‘warm’, and less likely to be ‘toxic’, according to traditional Chinese medicine (TCM) concepts. Roots were over-represented in the Bei region, and whole plants over-represented in Guang. Both the Chinese Pharmacopoeia and Daodi indicated preferences for families not common in previously studied ethnopharmacopoeias, and fewer endemic species were represented than expected by chance.Conclusion Using the phylogenetic and biogeographical methods, we highlighted patterns of plant use, and the biological characters of Daodi medicinal plants. Our study points towards cultural preferences in need of scientific explanation. 相似文献

Geographical Indications for Medicinal Plants:Globalization, Climate Change, Quality and MarketImplications for Geo-Authentic Botanicals 下载免费PDF全文
Pharmacopoeial standards for crude drugs are established based on analysis of authenticated specimens which should be representative of the
quality of material traditionally specified in systems of traditional medicine from species’ geographical origin. This reflects the ‘geo-authentic’
material that corresponds to traditional ecological and medical knowledge. In cases where specimens are obtained from cultivation outside of
the species origin, this ‘authenticated’ material will not be ‘geo-authentic’.
There is a growing trend for the protection of ‘geographical indication’ (GI) botanicals in the context of intellectual property rights. GI
botanicals are named after a geographical area, indicating production within a particular area, quality and characteristics dependent on natural,
historical and cultural factors. However, with the globalization of systems of traditional medicine such as Ayurvedic medicine and traditional
Chinese medicine, Asian species are being introduced to cultivation outside of their geographical origins particularly in the EU and US.
In contrast to the Chinese concept of ‘daodi’and European concepts of ‘provenance’ or ‘terroir’ is the competing trend for ‘locally grown’
herbs, i.e. cultivated closer to where they will be used. Reasons include concerns about quality control, contamination from polluted air, soil
and water in some source countries, climate change, supply chain security and traceability, costs of production and price pressure.
This review looks at selected agronomic experiments aiming to discern differences between geo-authentic medicinal herbs vs. introduced crops
and whether the global market cares to make a distinction or pay a price premium for articles with designations of geographical origin of
specified quality. 相似文献
