1.西贝素在不同温度下与氢氧化钾共熔,仅得一种产物,证明为西贝酮。2.西贝素用浓盐酸处理得氯代西贝素C27H42O2NCl,氯代西贝素用氢氧化钾醇液处理得脱水西贝素C27 H41O2N。3.西贝素用浓氢氧化钾醇液或乙醇钠的醇溶液处理得异西贝素。

When sipeimine was fused with potassium hydroxide at various temperatures (260Åto 320ÅC),there could be isolated only one and the same crystalline product.Based upon its empirical formula,physical and chemical properties and those of its derivatives,it was proved to be identical with sipeimone.Pyrolysis of sipeimine resulted only in the recovery of the original substance.
