Figure 2From: Larvicidal activity and possible mode of action of four flavonoids and two fatty acids identified in Millettia pinnata seed toward three mosquito speciesStructures of isolated compounds. The furanoflavonoid karanjin (1), the pyranoflavonoid karanjachromene (2), the unsaturated fatty acid oleic acid (3), the saturated fatty palmitic acid (4), the dihydrochalcone flavonoid pongamol (5), and the rotenoid flavonoid pongarotene (6). These constituents are identified in Millettia pinnata seed in this study. The chemical formulae of these compounds are C18H12O4 (1), C21H18O4 (2), C18H34O2 (3), C18H32O2 (4), C18H14O4 (5), and C18H10O4 (6); the molar masses are 292.29, 334.36, 282.46, 256.42, 294.32, and 291.06Â g/mol.Back to article page
