- W2390162008 abstract "Through AlCl3 and NaNO2-Al(NO3)3-NaOH derived system,total flavonoids of Hovenia dulcis Thunb was detected by spectrophotometry,taking rutin as a standard. The content of total flavonoids of Hovenia dulcis Thunb was measured at 283nm,taking naringin as a standard. Compared and analyzed the merits of the three experiments,the results showed that:taking naringin as a standard,the optimal method was to determine the total flavonoids of Hovenia dulcis Thunb in 283nm. Five kinds of advantages in this method,peak was detected obvious,content was determined accurately 3.28%,a wide range of determination was 5.0~25.0mg/mL,high precision:RSD=1.3% and the smallest relative error 0.21%." @default.
