Cardiac Glycosides from the Roots of Streblus asper.
A new cardiac glycoside "vijaloside" in addition to well known cardenolide, asperosid (digitoxigenin-2',3'-di- O-methylglucopyranoside) have been isolated and identified from the roots of STREBLUS ASPER. Repeated chromatgraphic manipulations and spectral analysis (IR, (1)H-NMR, (13)C-NMR and Mass), suggested the structure of vijaloside as periplogenein-3- O-beta- D-glucopyranosyl (1 --> 5)- O-beta- D-xylofuranoside.
