11种金花茶组植物叶片活性成分含量对比

摘要

In order to provide some references for breeding superior cultivars of Camellia nitidissima with high development and utilization values, main active components, total flavonoids, total polysaccharides, total saponins and tea polyphenols in leaves of 11 cultivars of C. sect. Chrysantha were determined by some routine methods. The results were analyzed by variance analysis and cluster analysis, and differences of medicinal value of C. nitidissima leaves from Guangxi and Vietnam were analyzed. The results show that main active medicinal ingredient contents had significant differences between C. nitidissima leaves from Guangxi and Vietnam. C. hirsute, C. crassiphylla and C. murauchii from Vietnam had higher medicinal value, and total contents of pharmacological active ingredients in leaves reached 38.03%, 38.91% and 36.62%, respectively. They had better cultivation and utilization values. However, contents of pharmacological active ingredients were lower in leaves of C. chrysantha, C. euphlebia and C. micrantha from Guangxi.%为给选育开发利用价值高的金花茶优良品种提供参考,以11种金花茶组植物为材料,采用常规方法测定其叶片中主要活性成分总黄酮、总多糖、总皂苷和茶多酚的含量,并进行方差分析和聚类分析,考查广西本地金花茶与越南金花茶叶片在药用价值方面的差异.结果表明,越南引种金花茶与广西本地金花茶叶片在药用活性成分含量方面存在显著差异;越南金花茶中的多毛金花茶、厚叶金花茶、黄抱茎金花茶,药用价值较高,其叶片中药理活性成分总含量分别达到38.03%、38.91%、36.62%,具有较好的栽培与利用价值;广西本地金花茶中的普通金花茶、显脉金花茶和小花金花茶的叶片中,活性成分含量较低.
