摘　　要：开发了一个具有农林特色的新的综合化学实验。以重瓣榆叶梅花为试样,用超声波辅助乙醇溶剂提取其中的黄酮,通过绘制芦丁标准曲线,用硝酸铝分光光度法测定提取液中黄酮含量。该实验由教师科研成果转化而成,已在本校分析化学实验课中开出,体现了“科教融合”。该实验可作为综合实验,供近化学专业低年级的分析化学实验课选用。A new comprehensive chemical experiment with the characteristics of agriculture and forestry was developed. Flavonoids was extracted by ultrasonic assisted ethanol solvent from prunus triloba f. multiplex flowers. Using calibration curve of rutin, the content of flavonoids was then determined by aluminum nitrate spectrophotometry. This experiment is from teachers’ scientific research achievements, and has been included in the analytical chemistry experiment course in our university to realize “integration of science and education”. The experiment can be used as a comprehensive experiment in analytical chemistry experiment courses for junior students of near-chemistry majors.
