摘要
Abstract
A method is established to determine benzoic acid and sorbic acid in wine by HPLC.The separation was achieved within 12 min by using a Eclipse XDB- C18 ( 250mm×4.6mm, 5μm ) with mobile phase 0.02 mol/L NH4Ac/methano1(95/5)and column temperature 25℃, lastly the determination was conducted at 230 nm through a ultraviolet detector (VWD).The results showed that the method detection limit, average recovery and relative standard were 0.057 mg/L(benzoic acid) and 0.049 mg/L (sorbic acid), 90％ to 106％ and 0.65％(benzoic acid) and 0.3 3％ (sorbic acid) respectively.The method is simple, rapid, accurate and highly sensitive.It is suitable for determination of benzoic acid and sorbic acid in wine.关键词
