Abstract

A new naphtho[2,3-c]furan-1(3H)-one derivative, 6,8,9-trihydroxynaphtho[2,3-c]furan-1(3H)-one (1), has been isolated from the stem bark of Rhamnus kanagusukii, together with eight known compounds, chrysophanol (2), emodin (3), rhamnazin (4), kaempferol (5), apigenin (6), taxifolin (7), ferulic acid (8), and gallic acid (9). The structure of new compound 1 was determined using spectroscopic and MS analyses. Among the isolated compounds, 6,8,9-trihydroxynaphtho[2,3-c]furan-1(3H)-one (1), kaempferol (5), apigenin (6), and taxifolin (7) showed potent inhibition with IC₅₀ values of 19.48 ± 1.52, 20.48 ± 1.84, 16.47 ± 1.25, and 15.44 ± 1.02 μM, respectively, against LPS-induced NO generation. In addition, compounds 5, 6, 7, 8, and 9 also showed potent DPPH radical scavenging activities with IC₅₀ values of 21.11 ± 1.84, 22.47 ± 2.04, 13.02 ± 1.07, 14.54 ± 1.35, and 13.48 ± 1.16 μM respectively.
