Fig. 4From: Harmine suppresses hyper-activated Ras–MAPK pathway by selectively targeting oncogenic mutated Ras/Raf in Caenorhabditis elegansHarmine is the most abundant compound in both DCM and EtOAc fractions. a and b Base peak ion chromatogram (BPI) analysis of the DCM and EtOAc fraction in positive ion mode. The highest peak was analyzed and the MS spectrum in a higher energy scan is shown in the upper rectangle. Both fractions share similar BPI patterns, and the most abundant component is harmineBack to article page
