Methanol extracts of peanut (Arachis hypogaea L.) pods were chromatographed, which yielded 3 phytochemicals 1-3 including 5,7-dihydroxychromone (1), eriodictyol (2), and 3",4",5,7-tetrahydroxyflavone (3). To confirm the presence of isolated phytochemicals, the pods extracts were performed by high performance liquid chromatography coupled with a photodiode array detector (HPLC-PDA) and a mass spectrometric detector (MSD) with electrospray ionization (ESI). Optimum extraction conditions for phytochemical contents using peanut germplasm were obtained by employing 90% MeOH for 12 hr at room temperature and phytochemicals 1-3 showed significant differences with concentrations of 407.56±23.35, 52.92±5.11, and 2,024.34±134.18 μg/g, respectively. Under this optimal conditions, the contents of phytochemicals 1-3 in peanut pods of 3 Korea cultivars including ‘Jakwang’, ‘Daekwang’, and ‘Palkwang’ exhibited phytochemical 3 was the highest range of 1,338.01-5,162.93 μg/g, followed by phytochemical 1 (590.13-1,382.10 μg/g), and phytochemical 2 (25.12-186.85 μg/g), respectively. Moreover, ‘Jakwang’ exhibited the highest contents of phytochemical (1: 1,362.10±52.49, 2: 186.85±17.69, and 3: 5,162.93±148.64 μg/g, respectively), whereas the lowest contents was found in the ‘Daekwang’ (1: 90.13±22.23, 2: 25.12±2.45, and 3: 1,338.01±62.17 μg/g, respectively). These results suggest that the methanol extracts of peanut pods may possess health related benefits to humans owing to various known biological activities of phytochemicals 1-3.
