Objectives : As a substitute for high-price ginseng, this study attempted to examine a possibility of the ferment extract of Panax ginseng sprout whether leaves and roots can be used together as a cosmetic ingredient with anti-oxidative and wrinkle-care effects. Methods : In terms of a test method, antioxidant activities were confirmed through total polyphenol contents, total flavonoid contents, DPPH radical scavenging activity and ABTS radical scavenging activity using the Panax ginseng sprout. In addition, to assess wrinkle-care effectiveness, the cytotoxicity of the extract was analyzed through MTT assay, and inhibition of collagenase activity in the cells was tested using the Panax ginseng sprout fermented by Saccharomyces cerevisiae. Resuits : The content of polyphenols and flavonoids in natural plants was highest in Panax Ginseng Sprout Extract at 100℃, which also demonstrated high DPPH, ABTS radical scavenging activity. MTT assay demonstrated that the Panax Ginseng Sprout Ferment Extract did not have a cytotoxic effect in CCD-986SK cell. Also, Panax Ginseng Sprout Ferment Extract was found to inhibit MMP-1 expression by 51.85±6.09% at a concentration of 10%. Conclusions : Therefore, this study has confirmed a possibility of Panax ginseng sprout ferment extract as a cosmetic ingredient with MMP-1-inhibitory effects.

The causal organism of Phytophthora disease on Panax ginseng Meyer in Korea was isolated and identified as Phytophthora cactorum. It's pathogenicity, etiology, and possible control measures were investigated. Disease symptoms on various parts of ginseng plants were also described The fungus caused seedling and mature plant blight and root rot. Oospores were easily formed on potato dextrose agar and corn meal agar. Oospores, however, were not formed in the diseased root tissues but did in the in footed shoots such as leaves, petioles, and stems and in the inoculated berries.

Variation in the inflorescence of Oriental ginseng (Panax ginseng C.A. Meyer) have been placed in 6 groups; only 2 of these groups, a complete simple hemispherical terminal umbel, and a simple umbel with several branched pedicels below it on the peduncle were found in cultivated American ginseng. Apical peduncle reflexing and associated peduncles shortening were observed in a few plants.

We studied the chloroplast rearrangement, short-term regulation depending on the light conditions in plants, and the characteristic of photosynthic rate as affected by in Panax ginseng C.A. Meyer. The chloroplast rearrangement of ginseng mesophyll cell was induced with the irradiation of blue light (400~500 nm) and through this process the rate of leaf transmittance increased 5~7.5%. The time to reach the maximum value of photosynthesis was shorter above 20 minutes with the blue light irradiation than that of the red light.

The graminicides fluazifop-p-butyl and sethoxydim effectively controlled annual grass weeds in 1,2 and year old ginseng crops during a 2 year study. Ginseng plants in the graminicide treated plots showed an early senescence of the shoots ; and at harvest the average root weight (g/root) and yield (kg/m) were slightly lower in these plants than in the untreated check plots. Roots of the graminicide treated plots remained viable to regenerate shoots. The greenhouse study indicated that shoot growth and seed development in ginseng plants were more sensitive to the graminicide treatment than the roots.

The sapogenins of two-and four-year-old A-merican ginseng plants (Panax quinquefolium L.) (Araliaceae) collected in July and September were studied. American ginseng saponins (panaquilins) differ from Korean ginseng (Panax ginseng C. A. Meyer) saponins (ginsenosides). The American ginseng saponins separated and named were panaquilins A, B, C, D, E-l, E-2, E-3, G-l, G-2, (c) and (d). One-dimensional thin-layer chromatography did not completely separate panaquilin mixture and were subject to misinterpretation. The panaquilins were more accurately separated and identified by the two-dimensional thin-layer method established. Some differences in American ginseng saponins were dependent upon the plant age, time of collection, and part extracted. The American ginseng sapogenin components are panxadiol (panaquilins B and C), oleanolic acid (panaquilin D) and panaxatriol (panaquilin G-l). The panaquilins E-l, E-2 and E-3 mixture contains both panaxadiol and panaxatriol. The genins of panaquilins A, (c), (d) and G-2 were not identified. In addition, ${\beta}-sitosterol$ and stigmasterol were identified from the root ether extracts.

In order to establish the integrated management of white grubs in ginseng field damages of ginseng plants (Panax ginseng C.A. Meyer) by the larvae of the larger black chamfer (Holotrichia morose Waterhouse) and the Korean black chamfer (Holotrichia diomphalia Bates) were investigated. Most of ginseng damages due to H, morose usually occurred in September through October, mainly on 2nd year plants. However, the damage by H. diomphalia occurred in September through October (usually in odd number of years) on 2nd year plants and in the following May and June on 3rd year plants. Therefore, in the fall of every odd number of years, synchronized occurrence of the two species caused severe damage on ginseng plants. Both of the 3rd instar larvae of the forementioned two species damaged ginseng roots regardless of the age of the plants when ginseng plants were artificially infested with them. Ginseng fields located at the slopes with good drainage are most likely damaged by them.
