Abstract:  A method was developed for the quantitative analysis of organic acids in Actinidia chinensis by GC. The sample was etherified in 10% H2SO4-CH3OH, followed by extraction with CH2Cl2, and determined by GC. The results showed that method has high recovery(93.8%~102.3%), good correlation(0.9991~0.9998) and good reproducibility(RSD<5%). The main organic acids inA ctinidia chinensisa re:malic acid, citric acid, palmitic acid, oleic acid and linoleic acid.

Key words: GC, Actinidia chinensis, organic acid, methyl etherification
