摘要
通过对3个藤茶品种的不同器官、不同加工方式以及不同存放时间总黄酮和二氢杨梅素含量进行测定,结果表明:藤茶不同部位的总黄酮含量存在显著差异,其中根的总黄酮含量最高,为235.03mg/g;叶的二氢杨梅素含量最高,为3.93mg/g;采用晒干方式加工的藤茶叶的总黄酮和二氢杨梅素含量均最高,分别为212.74mg/g和4.72mg/g;存放1年的藤茶叶的总黄酮含量最高,为192.82mg/g;存放2年的二氢杨梅素含量最高,为14.42mg/g。
Contents of total flavones and dihydromyricetin in different organs of three Ampelopsis grossedendata varieties,by different processing ways,and storage time were studied in order to provide references for their reasonable utilization.The results showed that significant differences of total flavones were observed in different organs of Ampelopsis grossedendata,and the highest content of total flavones was in root,the average value of which was 235.03 mg/g;The content of dihydromyricetin was the highest in leaves,which was 3.93 mg/g;and the contents of total flavones and dihydromyricetin were both the highest when dried in the sun,which were 212.74 mg/g and 4.72 mg/g,respectively.When stored for a year,the average total flavones content in leaves of Ampelopsis grossedendata peaked in average at 192.82 mg/g,and the average dihydromyricetin content peaked at 14.42 mg/g when stored for 2 years.
