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％。[著者文摘]

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%.[著者文摘]
