Abstract

Studies on the pharmaco-constituents from the leaves of Cercts chinensis which have been used for the treatment of inflammation, contusion, dilated blood, pain of heart and stomach, edema, etc. in Korean folk remedies were carried out. Dried leaves of the plant were extracted with MeOH. The MeOH extract was suspended in distilled water and subsequently fractionated with $Et_{2}O$ and n-BuOH. From the $Et_{2}O$ and n-BuOH fractions, six phenolic compounds were isolated and identified as myricitrin($C_{21}H_{20}O_{12}, {\;}m.p.{\;}199~200^{\circ}$. $4myricetin-3-O-{\alpha}-L-rhamnopyranoside$), kaempferol($C_{15}H_{10}O_{6}, {\;}m.p. 276^{\circ}$), quercetin($C_{15}Ha_{10}O_{7}, {\;}m.p.{\;}313~314^{\circ}$), quercitrin ($C_{21}H_{20}O_{12}, {\;}m.p.{\;}176~178^{\circ}, {\;}quercetin-3-O-{\alpha}-L-rhamnopyranoside$), gallicin ($C_{8}H_{8}O_{5}, {\;}m.p.{\;}202~203^{\circ}$. methyl gallate), gallic acid ($C_{7}H_{6}O_{5}, {\;}m.p.{\;}260~265^{\circ}) through their physico-chemical data and UV, IR, EI-MS, $^{13}C-NMR$, and $^{1}H-NMR$ analysis with authentics.
