Title: Research on the Total Flavonoid of Tea by Microwave-Assisted Extraction
Abstract: The microwave-assisted extraction of tea flavonoid,through the single factor and orthogonal experiments,was investigated to optimize the factors affecting the extraction rate of total flavonoid.The results showed that extract rate of tea total flavonoid reached to 9.54 mg/g under the optimum extraction conditions A3B2C3: 80% ethanol aqueous solution as the extracting solvent,the microwave power of 648 W,the microwave extraction time of 4 min,the solid to liquid ratio of 1∶ 45(g/mL).The effects of factors on the extraction rate of total flavonoid were extract powerextraction time solid-liquid ratio.
