    Abstract:
    Snake melon (Cucumis melo var. flexuosus, CM) is a gourd with health-promoting nutritional traits and unexplored phytochemicals. This study aims to comprehensively investigate the phytoconstituents in the fruits, leaves, roots, seeds, and stems of CM, using liquid chromatography-quadrupole time-of-flight tandem mass spectrometry. Consequently, 118 metabolites were identified, encompassing phenolic compounds, flavonoids, megastigmanes, lignans, cucurbitacins, and fatty acids. Multivariate data analysis revealed differences in the metabolite composition of CM organs and correlated these variations with the potential in-vitro anti-inflammatory properties assessed against RAW 264.7 macrophages through the down-regulation of cyclo-oxygenase-Ⅱ, nuclear factor-kappa B, and tumor necrosis factor-α. The results indicated that leaf and seed extracts showed the highest anti-inflammatory activity due to their enrichment in several flavonoids, phenolic glycosides, and a megastigmane. These findings emphasize the health benefits of CM organs as potential functional foods and functional food by-products, serving as a natural source for developing new anti-inflammatory agents.
