摘要
目的:促进光皮木瓜资源的综合利用。方法:采用Box-Behnken试验设计和响应面分析法,优化木瓜黄酮和多糖复合提取工艺。结果:超声波法提取光皮木瓜黄酮和多糖的工艺条件为超声波功率480W、提取时间35min、温度73℃、液料比为90:1(mL/g),黄酮和多糖总得率为15.62%,比热水浸提法总得率提高了21.46%。结论:超声波法提取光皮木瓜黄酮和多糖复合物得率较高。
Objective： To make comprehensive utilization of Chaenomeles sinensis （Thouin） Koehne. Methods： Box-Behnken experimental design and response surface methodology were used to optimize ultrasonic-assisted extraction conditions of simultaneous extraction for flavonoids and polysaccharides from Chaenomeles sinensis （Thouin） Koehne. Results： The optimal extraction conditions were ultrasonic power of 480 W, extraction time of 35 min, extraction temperature of 73 ℃ and material- liquid ratio of 1：90 （g/mL）. Under these optimal conditions, the total yield of flavonoids and polysaccharides was up to 15.62%, an increase of 21.46% when compared with hot water extraction. Conclusion： The total yield of flavonoids and polysaccharides during the simultaneous extraction from Chaenomeles sinensis （Thouin） Koehne is improved by ultrasonic-assisted extraction.
