  • The leaves of eggplant (Solanum melongena L.) were extracted with 80 % aqueous MeOH, and the concentrated extract was partitioned with n-hexane, EtOAc, n-BuOH, and water fractions. From the n-BuOH fraction, five compounds were isolated through the repeated silica gel, octadecyl silica gel, and Sephadex LH-20 column chromatographies. On the basis of physic-chemical and spectroscopic data including mass spectrometry, infrared spectroscopy, and nuclear magnetic resonance, they were identified to be caffeic acid (1), chlorogenic acid (2), cryptochlorogenic acid (3), panasenoside (4), and (6R,7E,9R)-4,7-megastigmadien-3-one-9-${\beta}$-${\small{D}}$-glucopyranoside (5). Compounds 3 and 4 were isolated for the first time from the leaves of S. melongena L. in this study.
