Specioside a new iridoid glycoside from catalpa speciosa


, : Specioside a new iridoid glycoside from catalpa speciosa. Journal of Natural Products (Lloydia) 43(4): 524-526

The ethanolic extract of the leaves of C. speciosa, with feeding deterrent activity against the gypsy moth larvae, [Lymantria dispar] was fractionated by solvent partitioning and column chromatography. Two weakly active compounds were isolated and identified by spectral and chemical methods to be catalposide (1) and a new iridoid, specioside (2).
