摘要:

药用植物淫羊藿主要分布于我国, 在中药、功能性食品和园林观赏等领域具有重要用途。目前淫羊藿药材主要依靠野外采摘, 过度的采挖已经对淫羊藿野生资源造成严重威胁和破坏, 必须采取有效策略, 推进淫羊藿资源的保育和可持续利用。人工栽培、野生抚育与人工半抚育是保护淫羊藿野生资源的重要途径。此外还可采用植物代谢工程、细胞工程、组织培养与微生物发酵工程技术生产淫羊藿有效成分黄酮类化合物, 减少野生药材的采挖与消耗。全面调查不同种淫羊藿中药理活性成分的种类和含量以及提高有效成分的提取收率对于野生药材保护也具有一定的作用。对于一些珍稀濒危的淫羊藿种质资源, 还应采取必要的行政监管手段加以保护。

Abstract:

Herba Epimedii is a unique and traditional Chinese medicinal plant that plays important roles in traditional Chinese medicine, functional food and landscaping design. Currently, wild Epimedium plants are the main source of the Chinese medicinal material. Wild harvesting has depleted the natural population to such a degree that the plant has become threatened with extinction for certain species. As a result, conserving and utilizing the wild Epimedium species sustainably is essential. Good agricultural practice cultivation, production in natural habitats and wild-simulated production of Epimedium species are efficient methods for increasing the supply and protecting the wild resource. The flavonoids for the important pharmacological activities of Herba Epimedii can also be produced by biological techniques such as metabolic engineering, cell and organ cultures and microbial fermentation, which might provide alternative strategies to reduce the consumption of wild plant resources. Additionally, understanding the phytochemical components comprehensively for different Epimedium species and improving the extraction recovery of the bioactive ingredients to optimize the usage of different species and protect the wild plants are important. As well, further administrative efforts should be employed to ensure the conservation of the rare and endangered germplasm.
