Secoiridoid Glycosides from Jasminum Polyanthum

Abstract Chemical investigation of the ethanolic extract of Jasminum polyanthum Franch has resulted in the isolation of verbascoside (10) and 9 secoiridoid glycosides including oleoside dimethyl ester (1), 10‐hydroxy oleoside dimethyl ester (2), oleoside 11 methyl ester (3), methyl‐glucooleoside (4), 8‐epikingiside (5), ligustroside (6), angustifolioside B (7), oleuropein (8), and oleoacetoside (9). The structures of 1‐10 were established primarily on the basis of NMR analysis.
