The fruits of Schisandra chinensis have been used as an edible ingredient and traditional medicine in Korea. Due to morphological similarities of dried mature fruits, the correct identification of S. chinensis from other closely related Schisandrae species is very difficult. Therefore, molecular biological tools based on genetic analysis are required to identify authentic Schisandrae Fructus. Random amplifed polymorphic DNA (RAPD) and Sequence Characterized Amplified Region (SCAR) were used to develop an easy, reliable and reproducible method for the authentication of these four species. In this paper, we developed several RAPD-derived species specific SCAR markers and established a multiplex-PCR condition suitable to discriminate each species. These genetic markers will be useful to distinguish and authenticate Schisandrae Fructus and four medicinal plants, S. chinensis, S. sphenanthera, S. repanda and K. japonica, in species level.

Vibrio become prevailing if superficial temperature of ocean is raised and their activities of area are expanded and most of ocean creatures(fishes, oysters etc) are polluted with vibrio. The one who has taken these polluted fishes and oysters uncooked caused foodpoisoning and diarrhea from Vibrio. Frequently these diseases breakout is disposed in westsea shore of Korea. According to ancient and traditional Korean medical book - Kumkue Yorak - and their single, we carried out experiment check the activities of natural medicinal effects on Vibrio parahemolyticus. The prescriptions of trial materials are processed from extraction boiling water and 80% methanol and followed by freeze dried and adsorbed to every discs in dosage of 10mg. Gentamycin of 10mg were used for control. The result of compound prescription displayed special diseases in antimicrobial activities of boiling water and MeOH extraction compared with control. In single prescription, extraction of boiling water and MeOH of Schisandra sphenanthera(clear zone : 15mm) presented extraordinal antimicrobial activity. The MBC of Schisandra sphenanthera extracts was expressed 2.56mg/ml in boiling water and MeOH.

Objectives : The original plant species of Schisandrae Fructus (O-mi-ja) is prescribed as Schisandra chinensis $B_{AILL.}$, in Korea, but S. chinensis $B_{AILL.}$ and S. sphenanthera $R_{EHD.}$ et $W_{ILS.}$ in China. Moreover, fruit of several other species in genus Schisandra also have been used as the same herbal medicines. To develop a reliable method for correct identification of Schisandrae Fructus and to evaluate the phylogenetic relationship of S. chinensis and its related species, we analyzed internal transcribed spacer (ITS) sequences of nuclear ribosomal DNA (nrDNA). Methods : Twenty-four plant samples of three Schisandra species and one Kadsura species, S. chinensis $B_{AILL.}$, S. spenanthera $R_{EHD.}$ et $W_{ILS.}$, S. nigra $M_{ax.}$ and Kadsura japonica $D_{UNAL}$ were collected from each different native habitate and farm in Korea and China. The nrDNA-ITS region of each samples were amplified using ITS1 and ITS4 primer and nucleotide sequences were determined after sub-cloning into the pGEM-Teasy vector. Authentic marker nucleotides were estimated by the analysis of ClastalW based on the entire nrDNA-ITS sequence. Results : In comparative analysis of the nrDNA-ITS sequences, we found specific nucleotide sequences including indels (insertions and deletions) and substitutions to distinguish C. chinensis, S. spenanthera, S. nigra, and K. japonica. These sequence differences at corresponding positions are avaliable nucleotide markers to determine the botanical origin of O-mi-ja. Moreover, we evaluated the phylogenetic relationship of four plant species by the analysis of nrDNA-ITS sequences. Conclusions : These marker nucleotides would be useful to identify the official herbal medicines by the providing of definitive information that can identify each plant species and distinguish it from unauthentic adulterants for O-mi-ja.
