Abstract: A new method for determination of D-glucaric acid 1,4-lactone in Kombucha by Gas Chromatography was introduced. This method had many merits in contrast with other test methods, such as high sensitivity, easy pretreatment, quick test,low cost and wide application etc. At the same time, the test results of the sample of Kombucha from Beijing have shown effective supports for the explanation of Kombucha’s effectiveness in detoxification and cancer prevention.

Key words: Kombucha, D-glucaric acid 1,4-lactone, gas chromatography
