柿叶中黄酮类化合物及提取工艺研究进展

柿叶来源于柿科柿属植物柿Diospyros kaki的干燥叶。柿叶中的主要化学成分有黄酮、三萜等，其中黄酮类化合物是中药制剂脑心清片的主要活性成分，在脑心清片治疗心脑血管疾病的过程中起关键作用，因此柿叶中的黄酮类成分具有较高的经济和药用价值。针对柿叶中的黄酮类化合物结构类型及柿叶黄酮的不同提取工艺进行综述，以期为柿叶中黄酮成分的深入开发和应用提供参考依据。

Research progress of flavonoids and extraction processes in persimmon leaves

Persimmon leaf derived from the dried leaves of Diospyros kaki Thunb, which belongs to the Diospyros genus and Persimmon family. The main chemical components are the flavonoids and triterpenes, among which flavonoids as the major active ingredients of preparation of Chinese medicine Naoxinqing Tablets, which play a key role in the treatment of cardiovascular diseases, therefore, the flavonoids in persimmon leaves posses high economic and medicinal value. In this paper, the structural types of flavonoids which have been reported in persimmon leaves and the different extraction processes of persimmon leaf flavonoids were reviewed, in order to provide a reference for the further development and application of the flavonoids in persimmon leaves.
