Abstract:
OBJECTIVE:To optimize the extraction and purification technology of resveratrol from Polygonum cuspidatum. METHODS:By alkali extraction and acid precipitation,an orthogonal experiment was conducted to optimize the extraction and purification technology taking the ratio of the CaO to the raw material,the ratio of solid material to the extraction solvent,the kinds of acid and the extraction time as factors and the weighted mean of the content and yield as comprehensive score index.RESULTS:The optimal extraction and purification technology was as follows:the ratio of CaO to the solid material was 9:100;the ratio of solid material to solvent was 1:8;the acid was hydrochloric acid and the extraction time was 45 min.CONCLUSION:The optimized extraction and purification technology of resveratrol from Polygonum cuspidatum is characterized by energy source - saving and simple in operation,and it is suitable for industrial production.
