摘要: 对喜树果中喜树碱的最佳醇提工艺条件进行了研究。采用乙醇浸提法,考查了乙醇浓度、液料比、提取温度及提取时间对喜树碱提取率的影响,经过一系列的单因素实验,结合响应曲面实验设计法及响应曲面分析(RSM),得到喜树碱的最佳提取工艺为:乙醇浓度 88.53%,液料比21.4:1(mL/g),时间2.23 h, 提取温度40 ℃,经验证,在此提取工艺条件下,喜树碱提取率可达0.847 mg/g。

Abstract: The ethanol extraction technology of camptothecin from Camptotheca acuminata fruits was optimized.Based on single-factor experiments and response surface analysis,the optimal extraction conditions were determined to be:ethanol concentration of 88.53% (v/v),liquid-to-solid ratio of 21.4:1,leaching time of 2.23 h, extraction temperature of 40 ℃.Under these conditions,the total extraction yield of camptothecin reached up to 0.847 mg/g (dry weight) by a series of industrial extraction & purification processes subsequently.This study offered an important experimental reference for further developments and utilizations of C.acuminata.
