Ⅱ-76 蘿芙木根中利血平的分离等,1959,[4],40 作者用印度产蘿芙木(Rauwolfia serpentina Benth)根为原料,重复了若干已發表的分离利血平的方法,發現这些方法步驟繁多,缺乏重演性。作者曾选用醇、甲醇、氯仿、二氯乙烷及它們的混合物作溶剂,結果發現用NH_30.5％飽和了的含乙醇量为10—30％的二氯乙烷为溶剂时,利血平收率最好。 Isolation of reserpine from Raliferae Ⅱ-76, 1959, [4], 40 The authors used the Indian Rauwolfia serpentina Benth roots as raw materials and repeated several published methods for the isolation of reserpine. These steps are found in many ways, the lack of repetition. The authors have chosen alcohol, methanol, chloroform, dichloroethane and their mixtures as a solvent and found that with NH_30.5% saturated ethanol containing 10-30% of ethylene dichloride as a solvent, reserpine The best yield.
