        试验中考察乙醇体积分数、液料比、提取时间和提取次数对山茱萸叶总三萜含量的影响;以齐墩果酸为对照品,采用紫外-可见分
        光光度法测定总三萜含量。在单因素试验的基础上,固定提取次数为3次,以总三萜含量为响应值,以乙醇体积分数、液料比、提
        取时间为响应因素,采用Box-Behnken设计-响应面法优化山茱萸叶总三萜的提取工艺并进行验证。结果:山茱萸叶总三萜的最
        佳提取工艺为乙醇体积分数73%、液料比38 ∶ 1(mL/g)、提取时间60 min。3次验证试验结果显示,山茱萸叶总三萜的含量分别为
        6.92%、6.91%、6.84%,平均含量为6.89%(RSD=0.63%),与预测值(7.28%)的相对误差为5.36%。结论:优化的提取工艺稳定、
        可靠,可用于山茱萸叶总三萜的提取。

        ABSTRACT    OBJECTIVE:To optimize the extraction technology for total triterpenes from the leaves of Cornus officinalis.
        METHODS:Based on the full swelling of the leaves of C. officinalis,total triterpenes was extracted with heating reflux method.
        The effects of ethanol concentration,liquid-solid ratio,extraction time and extraction times on the contents of total triterpenes from
        the leaves of C. officinalis were investigated by single factor test. Using oleanolic acid as control,the contents of total triterpenes
        were detected by UV spectrometry. On the basis of single factor test,fixing the times of extraction as 3 times,taking the contents
        of  total triterpenes as response value, using ethanol volume fraction, solid-liquid ratio and extraction time as factors,
        Box-Behnken design-response methodology was used to optimize the extraction technology of total triterpenes from the leaves of C.
        officinalis,and the optimized extraction technology was validated. RESULTS:The optimal extraction technology of total triterpenes
        from the leaves of C. officinalis were as follows as ethanol concentration of 73% ,liquid-to-material ratio of 38 ∶ 1 (mL/g),
        extraction time of 60 min. Results of 3 validation tests showed that the contents of total triterpenes from the leaves of C. officinalis
        were 6.92%,6.91%,6.84%;the average content was 6.89%(RSD=0.63%),relative error of which with the predicted value
        (7.28%)was 5.36%. CONCLUSIONS:The optimized technology is stable and reliable,and can be used for the extraction of total
        triterpenes from leaves of C. officinalis.
