| Abstract: | The contents of soluble solids,total acids and reducing sugars in Prunus mume sauce were analyzed,and the profile of organic acids,including oxalic acid,tartaric acid,malic acid,lactic acid,acetic acid,citric acid and succinic acid,was investigated with HPLC.The chromatographic column used was Zorbax SB-Aq C18(4.6×250 mm,5 μm).The conditions were as follows: mobile phase 0.01 mol·L-1 KH2PO4(pH 2.8),flow rate 1 mL/min,column temperature 30 ℃ and detection wavelength 215 nm.The recovery rate of organic acid was from 121.0% to 75.4%.The relative standard deviation was in the range of 0.78% to 2.12%.The detection limit ranged from 0.022～1.290 μg/mL.The results showed that the content of soluble solids,total acids and total reducing sugars were 59.45%,12.29% and 35.70%,respectively.Seven kinds of organic acids were detected in Prunus mume sauce,which were comparable with the contents of organic acids in Prunus mume fruit. |
