Abstract

From the ethyl acetate extract of the aerial parts of Jasminum subtriplinerve Blume (Oleaceae), 6′-O-menthiafoloylverbascoside (1), rutin (2), isoverbascoside (4), isooleoverbascoside (6), apiosylverbascoside (7), astragalin (9), isoquercitrin (10), and verbascoside (11) were isolated. Their structures were elucidated by extensive MS and NMR spectroscopy. Amongst 6′-O-menthiafoloylverbascoside (1) is a new phenylpropanoid glycoside.
