Abstract: The extraction condition of flavonoids from waxberry flesh by ethanol at assistance of microwave was studied. The single-factor experiments on effects of ethanol concentration, solid-liquid ratio, microwave power and irradiation time were conducted at first. The optimal extraction condition was obtained lately by orthogonal test. The results showed that the extraction yield of flavonoids was up to the top value of 3.45% in the condition of 60.0% ethanol, 1:40 of solid-liquid ratio, low rank of microwave power, and 4.0 min of irradiation time. Comparing with traditional technique, the irradiation extraction time decreased dramatically and extraction yield increased markedly.

Key words: waxberry flesh, flavonoids, microwave assisted extraction
