Two flavonoid triglycosides from Buddleja madagascariensis
- PhytoChemistry, 48(4), p.739-742, 1998 .
The structures of two new flavonoid triglycosides isolated from leaves of Buddleja madagascariensis have been established as hesperetin and diosmetin 7-O (2?,6? -di-O-?-l-rhamnopyranosyl)-?-d-glucopyranosides using mass and NMR spectroscopy. Scutellarein 7-glucoside is reported from this plant for the first time. Two new flavonoid triglycosides have been isolated from leaves of Buddleja madagascariensis: hesperetin and diosmetin 7-O(2?,6?-di-O-?-l-rhamnopyranosyl)-?-d-glucopyranosides.
