New Pregnane Glycosides from Gymnema sylvestre

Four new pregnane glycosides 1–4 were isolated from the ethanol extract of the stem of Gymnema sylvestre and named gymsylvestrosides A–D. Hydrolysis of compound 1 under the catalysis of Aspergilus niger β-glucosidase afforded compound 5 (gymsylvestroside E). Their structures were determined by spec...
