The optimization on extraction technology of total flavonoids from lotus leaves based on simultaneous ultrasonic/microwave assisted extraction and the analysis of high efficiency
The objective of the study was to optimize extraction technology of ultrasonic/microwave assisted extraction(UMAE) and to explain the reason for high-efficiency of this technology. The technology optimization was completed by the single factor experiment and orthogonal experiment of L9( 34). The reason for high-efficiency was explained by the comparison experiment,splitting analysis and scanning electron microscopy(SEM). The results of the optimal parameters of UMAE technology were the extracting time 5 min...
