Figure 1From: Petiveria alliacea extracts uses multiple mechanisms to inhibit growth of human and mouse tumoral cells Petiveria alliacea F4 fraction characterization. A. Upper panel shows compound UV spectra and retention time. Lower panel shows peak area and retention time. B. F4 fraction was subjected to MALDI-TOF-MS analysis. Numbers above the peaks correspond to m/z ratios. The horizontal axis represents the mean relative intensity and the abscissa m/z ratios. HCCA peaks correspond to matrix (4-cyano-4 hydroxy-cinnamic acid) signals. C. m/z ratio of compounds reported for Petiveria and compounds found in F4 fraction matching within (± 7) units of the m/z ratio.Back to article page
