Figure 5: Isolated compounds from N. indica. 7-Epiexaltoside (6), 6″,7″-Dihydro-7-epiexaltoside (7), Menthiafolin (8) and 3,7-di-O-methylquercetin-4′-O-β-glucoside (9), 3-O-methyl quercetin-7-O-β-glucoside (10) and 3,7-di-O-methy lquercetin (11). Finally, the phenolic coumarin, hydroxycinnamic acid, monoterpenoid and ester were also reported to be isolated and identified as scopoletin (12), ferulic acid (13), 8-hydroxy-2,6-dimethyl-(2E,6E)-octadienoic acid or foliamenthoic acid (14) and 6,7-dihydrofoliamenthoic acid methyl ester (15).
