The Korean folk medicine 'Jin Hae Cho Ip' has been used as a remedy for neuralgia and as an invigorating drug after a childbirth, etc in Korea. With regard to the botanical origin of 'Jin Hae Cho Ip', several species of Potentilla (Rosaceae) has been refired, but no pharmacognostical study has yet been performed in this regard. To clarify the botanical origin of the 'Jin Hae Cho Ip', the morphological and anatomical characteristics of the leaflets and petioles of Potentilla and Sibbaldia species growing in Korea, such as P. chinensis, P. cryptotaeniae, P. dickinsii, P. discolor, P. fragarioides var. major, P. freyniana, P. kleiniana, P. matsumurae, P. paradoxa, and S. procumbens, were compared. As a result, it was found that 'Jin Hae Cho Ip' was composed of the leaves of P. Chinensis and P. discolor.

A new speices, Potentilla gageodoensis M. Kim found in Is. Gageodo, Jeollanamdo Province, Korea, is firstly named and described. This species is similar to its related species P. fragarioides in having several characteristics like pinnately compound leaves, pubescent leaf blades and leaf petioles, different leaflets size, absent stolons, etc., but is distinct from P. fragarioides which has thin leaf textures, 7-13 leaflets, elliptic terminal leaflets, small petal size, and ciliate leaflet margin by having thick leaf textures, 5 leaflets, broadly ovate terminal leaflets, large petal size, and densely white ciliate leaflet margin.

The structures of six flavonoids isolated from heartwood of Prunus sargentii(Rosaceae) were analyzed by Mass and NMR spectrometry. These flavonoids were grouped into dihydroflavonol, flavanone, and flavanone glycoside, and identified as follows : 3,3',4',5,7-pentahydroxyflavanone(taxifolin) as a dihydroflavonol, 5-hydroxy-7-methoxyflavanone(pinostrobin), 4',5,7-trihydroxyflavanone(naringenin), 3',4',5,7-tetrahydroxyflavanone(eriodictyol), 5,7-dihydroxyflavanone(pinoccmbrin) as a flavanone and 7-hydroxyflavanone 5-O-${\beta}$-D-glucopyranoside(verecundin) as a flavanone glycoside.

Chaenomeles sinensis Koehne (Rosaceae) is a deciduous tree and is distributed in China, Korea and Japan. In previous studies on the fruits of C. sinensis, some triterpenoid compouds such as oleanolic acid, tormentic acid were reported. In an ongoing investigation into biologically active compounds from natural products, the methanol extract of the stems of C. sinensis was investigated. By means of the repeated column chromatography using silica gel, Sephadex LH-20, LiChroprep RP-18, betulin (1), tormentic acid (2), 1-${\beta}$-D-glucopyranosyl-3,4,5-trimethoxybenzene (3), lyoniresinol-2a-O-${\alpha}$-L-rhamnopyranoside (4) were isolated. The chemical structures of compounds 1-4 were determined by the basis of physico-chemical properties and spectroscopic methods such as 1D and 2D NMR. For the isolated compounds (1-4), the inhibitory activity of IL-6 production in TNF-${\alpha}$ stimulated MG-63 cell was examined. Among the isolates, betulin (1), 1-${\beta}$-D-glucopyranosyl-3,4,5-trimethoxybenzene (3), lyoniresinol-2a-O-${\alpha}$-L-rhamnopyranoside (4) showed inhibitory effects on IL-6 production in TNF-${\alpha}$ stimulated MG-63 cell.
