Abstract:
OBJECTIVE:To establish a method for determination of the content of quercetin in quercetin-PVP solid dis?persions.METHODS:The detection wavelength for dertermination of quercetin content was set at374nm.RESULTS:The caliberation curve was linear in the range of5.0~25.0?g/ml(r=0.9998).The average recovery was99.12%,RSD=0.70%(n=6).CONCLUSION:This method is stable,quick,accurate and simple,and is suitable for quality control of quercetin in quercetin-PVP solid dispersions.
