| Abstract: | Analysis of lactic acid in vegetables(e.g. waxgourd, chinese cabbage, radish, spinach)with Gas chromatography was studied. Retention time and internal standard method were used for qualitative and quantitative analysis, respectively. The standard curve of paeonilorin was y=2538 18643x(r=0.9985),recovery was 99.24%(RSD<0.70%,n=16).This method is easy and fast to operete ,and the result was sa tisfactory . |
