| Abstract: | Study the productive technology of flavonoids extract from leaves of loquat.The leaves of loquat was extracted with boiling water. The filtrate were adsorbed on macroporous exchange resin and eluted by 70 % ethanol. The alcoholic eluate after concentration was dissolved with ethanol. Filter the solution to remove, insoluble sediments, decompress and concentrate the solution to extract. Then dry in vacuum to obtain yellow powder. The total flavonoids contents was over 43 %. |
