6、至濾液澄清,用鹽酸調(diào)濾液的pH值至4,靜置沉淀,過濾,濾餅用煮沸過的水洗滌至無色,甲醇濾液精餾回收,橙皮苷的收率達(dá)85%以上。TCL鑒別出與橙皮苷對照品相對應(yīng)的寬點(diǎn)；HPLC法測定出橙皮苷純度為85.94%且理論塔板數(shù)不低于1000。結(jié)論：此方法操作簡便,易控制且提取橙皮苷的效率較高，所建立的定性定量方法專屬性強(qiáng)，重復(fù)性好。關(guān)鍵詞：青皮；橙皮苷；薄層色譜法；紫外分光光度法；高效液相色譜法AbstractExtractionandpurificationofhesperidinincicusprocessingandmeasuringi
