摘要: 利用星点设计-T型关联度分析法优化非洲育亨宾树皮中盐酸育亨宾提取工艺,在单因素试验的基础上选取乙醇体积分数、提取时间、液料比为影响因子,利用星点设计的3因素5水平试验设计影响因子为因子序列,盐酸育亨宾得率为对象序列,采用T型关联度分析优化。结果表明,影响盐酸育亨宾得率的影响因子主次分别为乙醇体积分数>提取时间>液料比,最佳工艺为:pH值9的 90% 乙醇重复提取3次,在液料比分别为10:1、8:1和6:1(mL:g)条件下回流提取,提取时间分别为2.5、2.0和 1.5h,产品得率为 8.76%,盐酸育亨宾质量分数为 8.45%。

Abstract: Central composite design and T-type correlation degree analysis was used for optimizing the extraction technique of yohimbinehydrochloride from African yohimbine bark. Based on single-factor experiment, three independent variables, namely:fraction ratio of ethanol, extracting time and solvent-solid ratio, were selected as affecting factors during extraction. The experiments were arranged according to central composite design and T-type correlation degree analysis.The results showed that the main factors affecting the yield of yohimbinehydrochloride were in sequence as follows:ethanol volume fraction>extracting time>solvent-solid ratio. The optimum technological conditions were as follows:ethanol volume fraction 90%(pH value 9), 3 times of reluxing extraction for 2.5, 2.0 and 1.5h, at solvent-solid ratio 10:1, 8:1, 6:1(mL:g) respectively. The yield of yohimbinehydrochloride was 8.76% and the content of yohimbinehydrochloride was 8.45%.

Key words: yohimbine bark, yohimbine hydrochloride, extraction, central composite design, T-type correlation degree analysis
