A process for extracting essence oil, fruit juice, pectin, edible fibres, naringoside, hesperidin, 3,3',3',5,6,7,8-heptamethoxy flavone and limonoid from pomelo fruit features respective use of cold grinding, squeezing, nano filtering, microwave or reflux extracting, ultrafiltering concentrating, chromatographic separating and alcohol extracting. Its advantages are high output rate and quality of products, easy removal of impurities, and no use of toxic and harmful organic solvent. 本发明涉及一种从柚子中同时提取香精油、果汁、果胶、食用纤维和柚皮甙、橙皮甙、3，3′，4′，5，6，7，8-七甲氧基黄酮单体及柠檬苦素类似物的方法。本发明以湖南江永香柚为原料，分别采用冷磨法、压榨法、纳滤、微波或回流浸提、超滤浓缩、色谱分离、乙醇浸提等得到不同产物。本发明能显著提高香精油的回收率和质量；能强化有效成分的溶出，缩短提取时间，提高产率，减少杂质溶出；利于蛋白质、淀粉等大分子杂质的去除，优于目前所用醇沉等分离技术；既节省能源，又避免活性成分的分解破坏；整个分离提取过程中不使用有毒有害有机溶剂，实现全流程绿色提取。
