摘要: A high pressure liquid chromatographic method that uses the benzoate ester of cholesterol has been developed for measurement in foods. 300 x 3.9 mm id muBondapak C18 column and a variable wavelength ultraviolet detector are used with 100% methanol mobile phase. Amounts as low 10 ng can be detected. The results from analyses variety foods given compared gas-liquid analyses. comparison 2 techniques is favorable.
