摘要：互花米草（Spartina alterniflora），原产美国东南部海岸，耐盐耐淹，有良好的促淤作用，1979年，出于生态工程的目的，有意引种进入我国，用于固滩护堤。但近年来由于其快速的繁殖扩散，大面积分布于我国沿海地区，严重破坏了生态环境，已被我国列为外来入侵物种。为了保护上海市滩涂资源生物多样性和可持续开发利用，充分利用互花米草的正面价值,尽量减少其负面影响，暂且不考虑实施成本和价值的情况下，提取互花米草叶片中的黄酮类物质就是挖掘其剩余价值的一种。本文介绍了通过水浴法对互花米草叶片进行黄酮类物质的提取，发现互花米草叶片中黄酮类物质在水浴60℃和70%乙醇浓度的最佳提取率为49.37%。发现通过提取互花米草中的黄酮类物质可以作为利用互花米草价值的一种。21291

Spartina alterniflora leaves extraction and content determination of flavonoids from tablets
Abstract: Spartina alterniflora grasses (Spartina alterniflora), native United States southeast coast, salt-tolerant of submergence, good silting, 1979, for the purpose of ecological engineering, intentional introduction into our country, for reinforcement the berm. But in recent years due to its fast breeding spread large area distributed in coastal areas of China, causing serious damage to the ecological environment, has been classified as invasive alien species in China. For the protection of biopersity and the sustainable exploitation and utilization of tidal flat resources in Shanghai, take full advantage of Spartina positive value to minimize its negative impact, without considering the cost and value of the case, extraction of Spartina alterniflora is the mining of flavonoids in the leaves of its residual value. This article describes the leaves of Spartina flavonoids were extracted through a water bath method, found the film Spartina grass flavonoids in a water bath 60 ℃ and 70% ethanol concentration optimal extraction rate of 49.37%. Found by extracting Spartina in flavonoids can be used as the value of the use of Spartina one.
