摘　　要：目的测定并比较不同生长期山楂叶中黄酮类化合物含量的差异。方法采用分光光度法和高效液相色谱法检测黄酮类化合物的含量。结果在不同的生长期,山楂叶中总黄酮和牡荆素鼠李糖苷的含量都在8月份最高,然后逐渐降低。结论以提取黄酮类化合物为目的的山楂叶最适宜在8月份采收。Objective To compare the contents of flavonoids in Hawthorn leaves of different growth stages. Methods The contents of flavonoids were determined by UV-spectrophotometry and HPLC. Results At different growth stages, the contents of total flavonoids and 2-O-Rhamnosylvitexin were the highest in August ; afterwards, the content of flavonoids decreased. Conclusion August was appropriate time in order to obtain flavonoids components from Hawthorn leaves.
