This study prepared the methanol extracts from 11 different kinds of Korean medicinal herbs and analyzed their functional components and various biological activities including anti-oxidation, anti-diabetes and anti-high blood pressure activities. The total polyphenol contents were higher in the order of Lespedeza cuneata (102.7 mg gallic acid equivalents (GAE)/g), Eleutherococcus senticosus (98.0 mg GAE/g), and Houttuynia cordata (66.1 mg GAE/g). The total flavonoid contents were higher in the order of L. cuneata (62.8 mg quercetin equivalents (QE)/g), H. cordata (23.6 mg QE/g), and E. senticosus (16.6 mg QE/g). The 1,1-diphenyl-2-picrylhydrazyl and 2,2’-azino-bis(3- ethylbenzothiazoline-6-sulfonic acid) radical scavenging activities were higher in the order of E. senticosus (87.9% and 90.9%, respectively), H. cordata (83.1% and 87.9%, respectively), and L. cuneata (79.3% and 85.8%, respectively). The results of ferrous reducing antioxidative power assay were higher in the order of L. cuneata (169.5 mg Trolox equivalents (TE)/g), E. senticosus (165.5 mg TE/g), and Kalopanax pictus (62.4 mg TE/g). The results of angiotensin converting enzyme inhibition assay were higher in the order of Lycium chinense (19.2%), K. pictus (16.8%), and L. cuneata (13.5%). The results of α-glucosidase inhibition assay were higher in the order of L. cuneata (93.7%), Cornus officinalis (50.9%), and Cnidium officinale (28.9%). Overall, these results will help to analyze functional components and to investigate various biological effects of these traditional Korean medicinal herbs.
