【正文】 oven with40 minutes . Getting the purified rutin. Alkali solution and acid precipitation is soaked Sophora japonica with distilled water, Adding calcium oxide g. adjusting the PH to 8, Boiling the Solution with 30 minutes, then filtering the solution and carried out the residue again, Collecting the filtrate in beaker and Adjusting the filter’s PH to 5 with concentrated hydrochloric acid. Standing the filter and precipitating pletely. Collecting the precipitate by the filtration. The precipitate is crude extract rutin. Recrystallizating the crude extract rutin in 6070 ℃ water bath and boiling the recrystallizate’s solution on electric furnace with 15 minutes. Filtrating the solution when it is hot and the filtrate aside until the precipitate pletely. Filtrating the solution, then collecting the precipitate. The precipitate dried at 65 ℃ in Vacuum oven with40 minutes. Getting the purified rutin. In this study, the alkali solution and acid precipitation better than ultrasonic 顯示對(duì)應(yīng)的拉丁字符的拼音字典Key words: Sophora japonica。超聲法是用70%乙醇溶液浸泡槐米粉，在超聲清洗器中進(jìn)行超聲處理30min，處理2次，收集濾液，用濃鹽酸調(diào)節(jié)PH值至3，靜置，至沉淀完全后，抽濾，收集沉淀得到蘆丁粗品，粗品在6070℃水浴中溶解，煮沸15min，趁熱抽濾，靜置濾液，待沉淀完全，抽濾，沉淀在65℃干燥40min，得到蘆丁的純化物；堿溶酸沉法是用蒸餾水浸泡，調(diào)節(jié)PH至8，加熱至微沸，保持40min，趁熱過濾，浸煮2次，收集濾液，用濃鹽酸調(diào)節(jié)PH至5，靜置至沉淀完全，將沉淀在6070℃水浴中，溶解，煮沸15min，趁熱抽濾，靜置濾液，待沉淀完全，抽濾，沉淀在65℃干燥40min，得到蘆丁的純化物。2011屆 分類號(hào)： 單位代碼 ：10452畢業(yè)論文槐米中蘆丁超聲法和堿溶酸沉法提取比較Comparation of Ultrasonic and Alkali solution and acid precipitation extracted Rutin from Sophora japonica1 摘
