摘 要 ：研究山里红中总黄酮含量随季节动态变化的规律,明确影响其总黄酮含量的气候因子。采收2013年5~10月的山里红,采用超声辅助提取法从山里红中提取总黄酮,三氯化铝比色法检测总黄酮的含量,并对山里红叶总黄酮含量与气候因子进行相关性分析。山里红不同部位总黄酮含量差异较大,9月份山里红叶黄酮类成分的含量最高,其值为31.52mg·g^-1。统计九月份山里红叶总黄酮含量与气候因子之间相关性分析,结果表明总黄酮含量与温度相关性显著。综合考虑,选择9月份为山里红叶的最佳采收期。该结果可为山里红叶总黄酮的深入开发利用奠定理论基础。

Abstract:We determined the contents of total flavonoids from Crataegus pinnatifida(C.pinnatifida) according to seasonal dynamics to find out the climate dominant climatic factors which influence the total flavonoids content(TFC) of C.pinnatifida. We studied the C.pinnatifida from May to October 2013, and used ultrasound-assisted extraction(UAE) to extract TFC from C.pinnatifida, and determined TFC by aluminum chloride colorimetric method. We analyzed the correlation between the TFC and climatic factors. TFC in different parts of C.pinnatifida had significant difference. TFC from C.pinnatifida leaves increase continuously and reach the highest point in September, with the value of 31.52 mg·g^-1. A positive correlation was between the content of total flavonoid and temperature. September was the best harvest time for C.pinnatifida leaves. Our result provides a theoretical basis for development and utilization of total flavonoids in C.pinnatifida.
