Different Parts

Phytonutrients, also called phytochemicals, are chemicals produced by plants. Foods and vegetables with phytonutrients have antioxidant and anti-inflammatory benefits. The aim of this study was to analyzed 4 parts of 3 lotuses phytochemical constituents by using gas chromatography mass spectrometry. Our results showed that different parts of lotus had a different chemical compound. The major chemical constituents in each extract are 6-Methoxy-2-[p-tolyl]cinchoninic acid (23.92%), Stigmastan-3, 5-diene (6.17%), 5(1H)-Azulenone, 2, 4, 6, 7, 8, 8a-hexahydro-3, 8-dimethyl-4-(1-methylethylidene)-, (8S-cis)- (24.44%), 2-Cyclohexane-1-carboxaldehyde, 2, 6-dimethyl-6-(4-methyl-3-pentennyl (18.15%), Stigmastan-3, 5-diene (24.04%), 2(1H)Naphthalenone, 3, 5, 6, 7, 8, 8a-hexanhydro-4, 8a-dimethyl-6-(1-methylethenyl)-(6.49%), 2-[p-Methoxyphenyl]-8-methylcinchoninic acid (12.98%), Ergosta-4, 6, 22-trien-3, beta, -ol (13.57%), and Stigmastan-3, 5-diene (26.05%). Therefore, Phytonutrients could also provide significant benefits for human’s health that eat plant foods.
