摘要: 以刺梨(Rosa roxbunghii Tratt.)果渣为原料,在单因素试验的基础上,运用Box-Behnken中心组合试验和响应面试验对刺梨蔷薇酸的碱提酸沉工艺进行优化。结果表明,碱液pH 12,提取120 min,液固比17∶1 (mL∶g),提取温度73 ℃,提取2次,蔷薇酸得率可达0.257%,与模型预测值基本吻合。在酸沉条件pH 2、乙酸乙酯1.0倍体积萃取2次后,蔷薇酸纯化得率可达3.77%。该方法简单、高效、节能、环保,为刺梨果渣中蔷薇酸的提取工艺提供理论依据。

Abstract: The pomace of Rosa roxburghii Tratt. was used as raw material,based on single factor experiments, the optimal extraction conditions for rosolic acid of Rosa roxbunghii Tratt. pomace by alkali extraction and acid precipitation method were optimized by Box-Behnken design and response surface methodology. The results showed that alkaline solution pH 12, extraction time 120 min, liquid-to-material ratio of 17∶1 (mL∶g), extraction temperature 73 ℃, extraction frequency 2, under this optimal extraction,the maximum yield of rosolic acid was 0.257% in accordance with the predicted value,indicating that extract parameters had good accuracy and reliability. The acid precipitation condition pH is 2, after extracting twice with 1.0 volume of ethyl acetate, the maximum yield of rosolic acid was 3.77%. This method is simple, efficient, energy saving and environmentally friendly, provide a theoretical basis for extracting rosolic acid from the Rosa roxbunghii Tratt. pomace.

Key words: rosolic acid, alkali extraction and acid precipitation method, Rosa roxbunghii Tratt. pomace, response surface optimization
