초록
Three wavelength spectrophotometry was used to determine the content of eugenol in Eugenia Caryophyllata Thunb. Using this method could effectively eliminate the deviation of background absorption caused by the change of concentration and the error of quantitative analysis caused by asymmetric peaks, and at the same time the leaning degree of base line was corrected. This method was simple the recovery ratio was 90.05%-116.94% and the coefficient of variation was 3.5%.
