摘要
用离子排斥色谱法,IonPacAS11阴离子交换柱,三种流动相系统(2mmol/L Na2B4O7、24mmol/L NaOH、18mmol/L NaOH)测定了桑椹原汁中的有机酸种类和相对含量,从桑椹原汁中检出的主要的有机酸有苹果酸、酒石酸、草酸、琥珀酸、柠檬酸、乙酸、甲酸等七种以及两种无机酸根Cl-、SO42-。
Mulberry raw juice organic acids were detected by ion exclusion chromatography, with anion exchange column (Ion Pac AS11) and three kinds of mobile phase (18mmol/L NaOH, 24mmol/L NaOH, 2mmol/L Na2B4O7) respectively. The main organic acids in the mulberry raw juice includ rnalic acid, tartaric acid, oxalic acid, succinic acid, citric acid, acetic acid and formic acid, while two kinds of inorganic radicals (Cl^-, SO4^2-) are identified.
