| Paulownia coreana, a deciduous species indigenous to Korea, has been extensively used in the wood industry and folk medicines. In the phytochemical study of its inner barks, one new phenylethanoid glycoside was isolated with six known compounds, r-coumaric acid, caffeic acid, verbascoside, isovervascoside, cistanoside F and campneoside II. Their structures was elucidated on the basis of chemical and spectroscopic evidence. Antioxidant activities of the isolated compounds, crude extracts and the partitioned fractions were evaluated by DPPH radical scavenging method. Most of the isolated compounds and EtOAc soluble fraction indicated significantly high antioxidant potential compared with BHT and a-tocopherol as controls. |
