%X A laboratory-scale experiment was done. And the baicalin anaerobic biodegradation curve and pathway were discussed by analyzing the results of GC-MS. After analogue of status's trend and analysis of its regression, the biodegradation kinetic equation of baicalin was obtained. And the possible biodegradation pathway was "desugar --> debentures --> open benzene ring --> saturating --> disconnect links". It took at least 47 h to biodegrade baicalin. The main products of anaerobic biodegradation were micro-molecule oxide, such as alcohols, aldehydes, acids, esters, olefin, and hydrocarbon of methane series. This result demonstrated that the rate-limiting steps of bacalin biodegradation were the hydrolyzing and acidification phase. It was suitable to use two-phase anaerobic process and long HRT to biodegrade baicalin.
