3-Hydroxycoumarin glycosides from Alyxia reinwardti var. lucida


, : 3-Hydroxycoumarin glycosides from Alyxia reinwardti var. lucida. Phytochemistry 34(3): 825-830

Investigation of the inner bark of Alyxia reinwardti var. lucida led to the isolation of two new coumarin glycosides, 1 and 2, whose structures were determined by interpretation of their spectroscopic data, particularly NMR spectroscopy.
