The extract obtained from the stem bark of Flacourtia ramontchi
was selected for its significant activity in both assays.
Six new
phenolic glycosides, named flacourtosides A−F (1−6), phenolic
glycosides itoside H, xylosmin, scolochinenoside D, and poliothrysoside,
and betulinic acid 3β-caffeate were obtained using the
bioassay-guided isolation process. Their structures were elucidated
by comprehensive analyses of NMR spectroscopic and mass
spectrometric data.
