and study of glucuronide metabolites is essential in many fields including pharmaceutical development, sports drug testing, and the detection of agricultural residues. Therefore, the development of improved methods for the synthesis of glucuronide conjugates is an important aim. The glycosynthase derivedfrom E. coli β-glucuronidase provides an efficient, scalable, single-step synthesis of β-glucuronides
The present invention provides isolated or essentially pure diterpenoic tetrahydropyran, such as steviol-19-glucuronide, steviol, stevioside and rebaudioside processes for obtaining the same and methods for obtaining stable pharmaceutically acceptable salts of the same for use of such compounds or compositions in a treatment of cardiovascular disorders or vascular disease or for the manufacture of medicaments to treat a condition of a cardiovascular disorder or vascular disease.

The glycosynthase derived from E coli beta-glucuronidase catalyzes the glucuronylation of a range of primary, secondary, and aryl alcohols with moderate to excellent yields. The procedure provides an efficient, stereoselective, and scalable single-step synthesis of 6-glucuronides under mild conditions.
