【摘要】 采用紫外-分光光度法测定了野葛花中的总黄酮、花青素和总多酚的含量,为野葛花深入开发利用提供理论依据.研究结果表明,野葛花在花蕾期、盛花期和终花期时总黄酮、花青素和总多酚含量存在显著差异,在盛花期时均达到最大值,分别是1.61%、2.12%和4.11%.提取野葛花的总黄酮、花青素和总多酚时,适宜在盛花期采收.更多还原

【Abstract】 The contents of total flavonoids,anthocyanin and total phenols from flower of flos pueraria in different florescence had been detected by using the ultraviolet-spectrophotometry,in order to provide the theoretical basis for further development and utilization of flos pueraria.The results showed that the content of total flavnoid,anthocyanins and total polyphenols were different in Flos puerariain different florescence,and in full flowering stage the contents were the highest,reaching 1.61%,2.12% and 4.11%. When extracting the total flavonoids,anthocyanin and total phenols from flower of Flos pueraria,we should choose the full flowering stage for collection.更多还原
