摘要
目的对长白楤木根、茎、叶中所含总黄酮的含量进行测定。方法采用紫外分光光度法于360nm波长处测定。结果总黄酮在4．08～32．64μg／ml范围内线性关系良好，其回归方程为：A=0．0183C＋0．0127，R^2=0．9992；平均加样回收率为100．63％（RSD=1．93％）。结论该方法简便、准确，可用于长白楤木的质量控制。
Objective To establish a method for the determination of the total flavonoids in roots, stalks and leaves of Aralia con- tinentalis Kitagwa. Methods The total flavonoids in roots, stalks and leaves of Aralia continentalis Kitagwa were determined by spectrophotometric method at 360 nm wavelength. Results Sample size showed a good linear relationship at the range of 4.08 ～32.64 μg/ml,and the curve was A =0.0183C ＋0. 012 7, R2 =0. 999 2. The average recovery was 96.2% and RSD was 1.42% （n = 6 ）. Conclusion This method is easy and accurate, and can be used for quality control of Aralia continentalis Kitagwa.
