Ultrasound-assisted Surfactant Extraction of Total Flavonoids from Bamboo Leaves
摘要
Abstract
The ultrasonic-assisted surfactant extraction of total flavonoids from bamboo leaves was optimized by one-factor-at-a-time method and response surface methodology. The extraction yield of total flavonoids was investigated with respect to ultrasound power, surfactant type, surfactant critical micelle (CMC) concentration and solvent-to-solid ratio. The results showed that the optimal conditions for the extraction of total flavonoids at 40 kHz ultrasonic power and ambient temperature were ultrasound power of 420 W, SDS as the extraction surface at a CMC of 25.20×10-3 mol/L, and a solvent-to-solid ratio of 23:1 (mL/g) (ratio of SDS solution to bamboo leaves). Under these conditions, the yield of total flavonoids was 2.30%.关键词
