[Glycosides from Mussaenda arcuata Lam. ex Poiret leaves].
Fractionation of the methanolic extract of Mussaenda arcuata leaves resulted in the isolation of four flavonoid glycosides and of two phenylpropanoid derivatives. The flavonoids were identified as astragalin 2, isoquercitrin 3, kaempferol-3-O-beta-D-rutinoside 5 and rutin 6 and the two phenylpropanoid derivatives as melilotoside 4 and dihydromelilotoside 1. This latter compound is a novel natural product. The structures of compounds 1-6 have been elucidated on the basis of their spectral data and of those of their acetyl derivatives.
