Janceolaroside A and Janceoside A,Two New Compounds from the Stems and Roots of Jasminum Lanceolarium

Abstract

From the stems and roots of Jasminum lanceolarium Roxb., two new compounds, janceolaroside A and janceoside A, have been isolated along with three known compounds, (-)olivil 4′-O-β-D-glucopyranoside, (+)-cycloolivil-6-O-β-D-glucopyranoside and syringin. The structures of the new compounds were determined by spectroscopic methods.
