title: C-Glycosyl flavonoids and coloratane-type sesquiterpene glucosides from the water-soluble fraction of a leaf extract of a Malagasy endemic plant, Cinnamosma fragrans (Canellaceae).
abstract: Leaves of Cinnamosma fragrans were extracted with MeOH, and the concentrated MeOH extract was partitioned with EtOAc and H₂O. From the H₂O-soluble fraction, three new flavonol C-glycosides and two coloratane glucosides were isolated, along with nine known compounds. On extensive spectroscopic analysis, C-glycosylation was found to have occurred on the B-ring.
