Flavanone Glycosides from Miconia trailii

Journal of Natural Products, 2002
Assay-guided fractionation of the ethanol extract of the twigs and leaves of Miconia trailii yielded two new flavanone glycosides, matteucinol 7-O-alpha-l-arabinopyranosyl(1-->6)-beta-d-glucopyranoside (miconioside A, 1) and farrerol 7-O-beta-d-apiofuranosyl(1-->6)-beta-d-glucopyranoside (miconioside B, 2), along with the known compounds matteucinol 7 ...

Flavanones from Baeckea frutescens

Phytochemistry, 1999
Three novel flavanones, named BF-4, BF-5 and BF-6, were isolated from the leaves of Baeckea frutescens. The structures of these flavanones were determined by their mass, 1H and 13C NMR spectral data. BF-4 and BF-5 showed strong cytotoxic activity (IC50=0.2–0.5 μg/ml) against leukemia cells (L1210) in tissue culture.

Flavanones from Lonchocarpus minimiflorus

Phytochemistry, 1987
Abstract Five novel flavanones have been isolated from the leaves of the Costa Rican tree Lonchocarpus minimiflorus , and characterized on the basis of their spectral features. Three of these compounds contain an uncommon prenyl cyclization, new to flavanone chemistry.

Flavanones and Dihydroflavonols

1975
This chapter is concerned with the closely related flavanones and dihydroflavonols. Flavanones are based upon structure (1), 2-phenylbenzopyran-4-one, which is flavanone itself. The parent compound is not known to be naturally occurring; the simplest plant flavanone has a hydroxy 1 group at position 7.
