Extraction Rates of Flavonoids from Ultrafine Powder vs.Fine Powder of Gleditsia sinensis / 中国药房

ABSTRACT

OBJECTIVE:To compare the extraction yield of total flavonoids from fine powder vs.ultrafine powder of Gleditsia sinersis.METHODS:The absorbance was detected under a wavelength of 510 nm by ultraviolet spectrophotometry. The extraction rates of flavonoids from fine powder vs.ultrafine powder of Gleditsia sinersis were computed.RESULTS:The extraction rate of flavonoids from ultrafine powder was 29.1%higher than that from the fine powder of Gleditsia sinersis. CONCLUSION:The extraction rate of flavonoids was increased by superfine comminution.
