Abstract
A quantitative determination method for total flavonoids in hawthorn fruit was developed using differential spectrophotometry (analytical wavelength 412 nm) and state standard sample hyperoside and was used to analyze a series of raw material samples. It was shown that the flavonoid content in hawthorn fruit varied in the range 0.112 – 0.183% (calculated as hyperoside). Statistical processing of the test results indicated that the error of a single determination of total flavonoids in hawthorn fruit at 95% confidence probability was ±4.87%.
