The extraction method of medicinal herbs using low temperature extraction with ultrasonic treatment

摘要

The present invention, while extraction at relatively low temperatures of 40 ℃ ~ 60 ℃ to reduce, such as denaturation of the active substance in the heat-related in relation to maintaining a high temperature in order to obtain a certain amount over the yield in manufacturing the hot-water extract of traditional herb herb, high It relates to the enhancement of the yield and physiological activity. ; To this end the present invention is combined with the yield of physiologically active to promote the extraction of the herb primarily by the addition of a solvent of a multiple of 10 samples at a temperature of 40 ~ 100 ℃ Next, ultrasonic waves according to drive 20~60Hz 2 herb extract after treatment, filtration under reduced pressure, a method of extracting and concentrated to produce a freeze-dried extract. ; Extract obtained through the present invention showed a high yield ranging from 2.6 times in FIG extracted at a temperature of 40 ℃ ~ 60 ℃ about 1.8 times the extract obtained in the same temperature of a simple hot-water extraction method from the existing 100 ℃, cancer cells in the promotion of growth and inhibition of the growth of immune cells it has a synergistic effect over 150 ~ 200% as compared to the extract obtained in the conventional simple hot water extraction method. ; Sonicated, filtered under reduced pressure, concentrated, freeze-dried
