Leaves. Result: Extraction temperature had effect on total flavonoids yield, and ethanol concentration had more obvious effect than extraction temperature. The more natural storage time, the less total flavonoids content, and the average descent rate was 24.74% per year. The flavonoids content from Lithocarpus polystachyus Rehd. gathered between August and October was the highest. The total flavonoids content was higher in the new leaves of Lithocarpus polystachyus Rehd.

结果：乙醇体积分数对总黄酮提取量有显著影响，提取温度对总黄酮提取量有影响；多穗柯自然存放时间越长，总黄酮含量越低，平均每年下降24.74%；不同季节采摘的多穗柯其总黄酮含量以8~10月最高；经对怀化多穗柯嫩叶和老叶中总黄酮的提取测定表明，多穗柯中嫩叶总黄酮含量最高，二年生最低。
