  • We investigated the effect of antioxidants (ascorbate, glutathione, and sodium azide), which efEectively inhibited the chlorophyll bleaching of Panax ginseng CA Meyer under the high light intensity, treated by folilar wiping on the early stage of photosynthesis and transpiration of ginseng in the 5000 $\mu$mol photon.$m^{-2}$.$s^{-1}$. Ascorbate and glutathione, endogenous antioxidant, completely recovered ginseng from the photoinhibition, but sodium azide, synthetic quencher, showed negative effect. We assumed that endogenous antioxidants could be available to the protection of the leaf-burning phenomenon of ginseng.

  • Mature zygotic embryos dissected from ginseng(Panax ginseng C. A. Meyer) seeds were cultured on Murashige and Skoog's (MS) medium containing various concentrations of 2, 4-dichlorophenoxyacetic acid(2, 4-D) and kinetin. Somatic embryos were induced directly from cotyledonary tissue or from intervening callus. The induction frequency of somatic embryos was up to 55%. Upon transfer to half-strength MS medium supplemented with 1 mg/1 6-benzyladenine(BA) and 1 mg/1 GA3, most somatic embryos developed into plantlets. Over 50% of the plantlets flowered after 4 weeks of culture and then a few bore immature fruits in vitro. Therefore, it is suggested that the juvenility of the ginseng tissue which give rise to somatic embryos does not interfere with in vitro flowering of their regenerated plantlets.

  • 분말상태의 인삼속 식물들의 품종 및 원산지를 판별하기 위하여 SAW 센서가 내장된 PHGC를 이용하여 향기 패턴을 분석하였다. 한국 백삼을 1로 기준할 때 전체적인 Rt에 대한 frequency pattern의 면적비는 화기삼 $0.248{\sim}0.871$, 전칠삼 $0.030{\sim}0.674$, 중국산 백삼 $0.005{\sim}0.212$ 범위로 나타났다. 분명한 차이를 나타내는 몇 개의 특정 향기성분의 면적비를 보면 $Rt_{20.02}$에서 한국산 백삼 1일 때, 중국산 백삼 0.212, 화기삼 0.343, 전칠삼 0.065이었다. 또한 $Rt_{21.70}$$Rt_{24.90}$에서 검출되는 향기성분의 면적비도 품종간의 차이가 뚜렷하였다. 한국산 백삼과 중국산 백삼에서 검출된 Rt_26.15 향기성분의 면적비는 각각 1과 0.185로 나타나 원산지간의 차이도 분명히 나타났다. $Rt_{26.15}$의 향기성분은 화기삼과 전칠삼에서는 검출되지 않았다. Frequency pattern, derivative pattern을 Vapor $print^{TM}$을 사용하여 도형화하여 비교한 결과 한국 백삼(Korean Panax ginseng C.A. Meyer), 화기삼(미국삼, 서양삼, Panax quinquefolium L.), 전칠삼(Panax notoginseng F.H. Chen), 중국산 백삼(Chinese Panax ginseng)은 서로 다른 패턴을 보여주어 품종간의 차이는 물론 원산지의 차이도 뚜렷하게 나타났다.

  • Effects of plant growth regulators on the germination of ginseng (Panax ginseng C.A. Meyer) seeds were investigated. Ginseng seeds germinated more vigorously in the treatments of kinetin and BA, and the promoting effect of kinetic on the germination and the growth of rootlet enhanced in low temperature ($10^{\circ}C$). However, GA did not promote the germination of dehiscent seed. The optimum temperature for germination of dehiscent seed was $10^{\circ}C$ and the range of effective concentration of kinetin for germination was 50 to 100 ppm.

  • 인삼(Panax ginseng C.A. Meyer) 종자단백질인 vicilin을 ammonium sulfate 침전, gel permeation 및 이온 교환 크로마토그래피로 정제하였다. Vicilin은 분자량 55,000(큰 소단위) 및 44,000(작은 소단위)인 두 종의 소단위를 포함하는 당단백질이다. Vicilin에 대한 항체를 토끼에서 형성시켜 DEAE-Affi-Gel Blue affinity 크로마토그래피로 정제하였다. 이 항체와 금 입자가 결합된 2차 항체를 종자의 배유세포에 반응시켰다. 금 입자는 배유세포내의 단백질체, 전자밀도가 높은 과립 및 골지체의 elaborating 과립에 표지되었다. 이러한 결과는 조면소포체에서 합성되어 골지체로 수송된 vicilin이 골지의 소포내에서 공정과정을 거쳐 전자밀도가 높은 과립이 된 다음 단백질로 수송됨을 나타낸다.

  • In An invertase (EC 3.2.1.26) was extracted from Korean giseng (Panax ginseng C.A. Meyer) with distilled tvater The ginseng invertase was purified about 62.6 folds purified by procedures including ammonium sulfate fractionation , DEAE-cellulofine chromatography and gelfiltrations through Sephadex G-75 and the recovery of enzyme activity was 11.1%. The homogeneity of the purified enzyme was probed by polyacrylamide gel disc electrophoresis. The purifled enzyme was divided into two different subunits by treating with a mixture of SDS and 2-mercautoethanol, and the molecular weight of the large subunit was estimatedtobe 116,000 and that of the small one to be 14,000. The optimal VH and temperature of the enzyme were pH 6 and 45$^{\circ}C$, respectively. The enzyme hydrolyzed specifically the hydrolyzation of the -fructofuranosides such as sucrose, raffinose and inulin. The Km values of the enzyme for sucrose and raffinose were determined to be 0.85 and 0.6 mM, respectively.

  • Some of the dammarane-type saponins. ginsenosides of Panax ginseng C.A. Meyer (Araliaceae) are now well established as a potent chemotherapeutic agent against a wide variety of aliments. Its various pharmacological and biological activities have been thoroughly reviewed (S. Shibata, 2001). The limited supply of the drug from the original source. the hairy root of the Panax ginseng promoted intense efforts to develop alternate sources and means of production. (omitted)

  • Two lignanes, Comp.-I, mp 108-1$0^{\circ}C$ and Comp.-II, mp 50-52$^{\circ}C$ were isolated from Korean ginseng extract by repeated column chromatographic purification. Comp-1 was identified as gomisin-N and Comp. -II as gomisin-A by spectrometric analysis, both of which have already been described as the anti-hepatotoxic lignin components of Schizandra chinensis Bail.

  • 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.

  • 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.
