| Abstract: | This article studies the condition and practicie method to determine the concentration of abellae stepholidinum with ultraviolet spectrophotometre. The results show that,at 282 nm wavelength, the absorbancy is linear respect to the concentration when the concentration of stepholidinum is from 00. 0100 to 0. 0500 mg·mL-1 in 0. 05mol·L-1H2SO4. The regression equation is A= 3. 02×10-4 + 17.12c, r =0.9996. The method given by the article is simple,quick and accurate. |
