  • In the screening of those components with comparatively strong xanthine oxidase inhibition activities from Panax ginseng folium. trifolin. panasenoside. kaempferol and so far unconfirmed phenol whose chemical structure still without elucidation have been discovered as such components. Specific inhibitors of xanthine oxidase are thought to be therapeutically useful for the treatment of gout. Such opinion is considered to be useful to support the thought that ginseng folium is effective for the adjustment of gout. Although trifolin. panasenoside. and kaempferol are well known flavonoids. further studies on unidentified new phenols should be continued.

  • The leaves of eggplant (Solanum melongena L.) were extracted with 80 % aqueous MeOH, and the concentrated extract was partitioned with n-hexane, EtOAc, n-BuOH, and water fractions. From the n-BuOH fraction, five compounds were isolated through the repeated silica gel, octadecyl silica gel, and Sephadex LH-20 column chromatographies. On the basis of physic-chemical and spectroscopic data including mass spectrometry, infrared spectroscopy, and nuclear magnetic resonance, they were identified to be caffeic acid (1), chlorogenic acid (2), cryptochlorogenic acid (3), panasenoside (4), and (6R,7E,9R)-4,7-megastigmadien-3-one-9-${\beta}$-${\small{D}}$-glucopyranoside (5). Compounds 3 and 4 were isolated for the first time from the leaves of S. melongena L. in this study.

  • Five ginsenosides $(A_1,\;A_2,\;B_1,\;B_2,\;C)$ and a yellow pigment were isolated from American ginseng stems and leaves. Ginsenoside $A_2,\;B_1,\;B_2$ and C were proven to be identical with Korean ginseng root ginsenoside $Rg_1,$ Rd, Re and $Rb_2,$ respectively. The yellow pigment proved identical with panasenoside isolated from Korean ginseng leaves. Ginsenoside $A_1$, which was also present in American ginseng roots, was not identical to any of the known root (ginsenoside $R_{0}-Rg_{2}$) and leaf (ginsenoside $F_{1}-F_{3}$) Korean ginseng saponins. A gas-liquid chromatographic method was developed to analyze ginsenosides and sapogenins in rabbit plasma and urine samples. Panasenoside and stigmasterol were found to be the best internal standards for ginsenosides and sapogenihs, respectively. Ginsenoside C had a significantly longer half-life, higher plasma protein binding, lower metabolic and renal clearance than ginsenoside $A_1,\;A_2\;and\;B_2$. Ginsenosides were not found in rabbit plasma and urine samples after oral administration. Ginsenoside C had a higher toxicity than ginsenoside $A_2$ after intraperitoneal administration to mice. Toxicity was not observed after oral administration of the ginsenosides.

  • Ginseng has been used as miraculous panacea since ancient times in oriental countries. In spite of voluminous work, ginseng still remains mysterious herb, but its value is becoming more recognized in the pharmaceutical and cosmetic fields. In this study, we investigated the effect of Panax ginseng on wound healing using two experimental methods. First, we studied the effect of ginseng on artificial wound of cultured human keratinocyte monolayer. Indivisual components from ginseng (ginsenoside Rb2, Rc, Re, Rg1, and panasenoside) and giseng extrats were examined. Of them, compared with control, ginsenoside Rb2 and Rg1 needed much shorter time to recover original appearance of momolayer. Second, we investigated the effect of ginseng on acute injury on dorsal skin of hairless mice. We here observed that ginseng has prominent effect than Madecasol(asiaticoside), a well known wound healing agent. These results were deduced that ginseng promoted wound healing in the wound region due to its stimulation of biosynthesis of various endogeneous materials that have relation to wound healing. Furthermore, we conformed that ginsenoside Rg1 exhibited anti-inflammatory activity on rat paw edema induced by carageenan. These results suggest that Panax ginseng C.A Meyer can be used in the cosmetics in that its wound healing and anti-inflammatory effects.
