摘要
The present study was designed to construct the structurally diverse library of tetrahydroprotoberberines(THPBs) by combining the methods of chemical nonselective demethylation and microbial glycosylation. HPLC-MS/MS analyses tentativelyidentified 12 de-methylated and 9 glycosylated derivates of THPBs and 5 rarely oxidized glycosides of THPBs in the library. Through this effort, we achieved not only a variety of the THPBs and their glycosides but also tested the catalytic characteristics and capabilities of G. deliquescens NRRL 1086.
