芒果叶中总黄酮的提取及含量测定

目的为充分利用芒果叶植物资源,避免资源的浪费,探讨芒果叶中总黄酮的提取及鉴别方法。方法采用纯物理的工艺流程过程从芒果叶中提取黄酮类物质,对所提取的黄酮类物质进行验证,并用分光光度法测定含量。结果测得样品中总黄酮的含量x=5．900mg/ml,回收率为97．33％,其纯度和产率均较高。结论该方法采用全物理过程, 无任何污染,是提取芒果叶黄酮类物质的有效途径。

The extraction and identification of total flavone from mango leaves

Objective In order to make full use of the mango plant resources, the process of extraction and identification of total flavone from mango leaves were studied. Methods A pure physical technological process was used to extract flavones from mango leaves, and the flavones were also identified. A spectrophotometry was used to assay the quantity of the flavones. Results In the samples, the quantity of the total flavone was x = 5. 900mg/ml, the rate of recovery was 97.33 %. The purity and the product yield of the total flavone were high. Conclusion This pure physical process without any pollution is an effective way for extracting flavones from mango leaves.
