摘　　要：通过对黄连进行醇提取和水提取，以蒸馏水浸泡为空白对照组对比化学保鲜剂咪鲜胺，研究其不同提取物处理后柑橘生理生化及营养成分的变化规律虻藏温度10℃，相对湿度85％～90％）。结果表明，黄连提取物较空白对照明显延缓了柑橘果实的腐烂，降低了果实的呼吸强度，抑制贮藏后期果实可溶性固形物、酸及VC含量的下降和丙二醛含量的积累，降低其PG和POD活性，其中黄连醇提取物的处理效果优于水提取物，且与咪鲜胺处理无显著差异。The objective of this study is to investigate effect of ethanol extracts and water extracts from coptis treatment on postharvest physiology of citrus. It compares with the treatment of water and prochloraz. The changes of physiology, biochemistry, as well as nutrient content are investigated. The results show that ethanol extracts from coptis, it can restrain respiration intensity, alleviate the decline of total soluble solids, titratable acidity, total soluble sugar and VC content, and accumulate of MDA remarkably, restrain the activity of PG and POD, and slow down the senescence of fruits. It is better than the effect of water extracts from coptis treatment, and there is no significant difference with prochloraz treatment.
