油松花粉中总黄酮的提取研究

Extraction of Total Flavonoids from Chinese Pine Pollen

摘要:

对油松花粉中总黄酮的提取条件进行了研究。其最优提取条件为：温度为70 ℃，溶剂乙醇浓度为60%，液固比为10:1，加热回流提取。在此条件下，用NaNO2-Al(NO3)3-NaOH显色法测定的总黄酮为1.41%。

Abstract:

The extraction conditions of total flavonoids from Chinese pine pollen were studied in this paper. The optimum reflux extraction conditions were as follows: temperature of 70 ℃, ethanol content of 60% and ratio of solid to liquid of 10:1. In these conditions, the content of flavonoids in the extracts was 1.41%.
