Optimization of Ultrasonic-Assisted Eztraction of Flavonoids with Ethanol from Ginkgo Leaves by Response Surface Methodology

摘要：

Response surface methodology (RSM) was applied to predict optimum conditions for ultrasonic-assisted extraction of flavonoids from ginkgo leaves. A central composite design involving ultrasonic time, extracting temperature and extracting time was used, and second-order model for flavonoid purity was employed to generate the response surface. The optimized condition was as follows: ultrasonic time 21.66 min, extracting temperature 39.34℃ and extracting time 2.01 h. The predicted flavonoid purity at condition was 40.75 mg/g. Experimental verification gave the value of 40.62 mg/g.
