A Study on the RNA, DNA Contents at Each Part of Each Year Ginseng Root
LEE, U YOUN,LEE, GAPDUK,LEE, MYUNGSUN 동국대학교 대학원 1977 大學院硏究論集-東國大學校 大學院 Vol.7 No.-
This was to study the amount of Nutleic acid in three parts (head, trunk, tail) of each year (from two year roots to six year roots) ginseng cultivated in Kang Wha, Korea. The results were as follows; 1). In head parts, the highest content of RNA was contained in five year ginseng roots and the lowest in two year ginseng roots. RNA content of siz year ginseng roots falled down rapidly. DNA content was also same phenomenon as RNA content. 2). In trunk parts, the relative ratio of RNA and DNA contents for each year roots was as like in head parts. However the lowest amount of total Nucleic and was contained in this part among the three parts. 3). In tail parts, th amount of RNA and DNA was also as like the others. Total Nucleic acid content was the highest in this part among the three parts. Ginseng was recorded for the first time in the world as a name of Sam (蔘) at era of Won Dinasty (B.C.34-48), ancient China. Korean ginseng (Panax Ginseng C.A. Meyer) has ever increasing on its efficency since prehistoric era in the Orient. Especilly chemical components of ginseng has studied for a long time by scientists. The first report about ginseng components was by Garriques in 1854. He separated Saponin from American ginseng (Panax quinquefolium L.) and named it Panaquilon. Now among the various components of Korean ginseng, triterpene glycosides of dammarane series which were known to be the effective components and also known to be the ginseng specific component, were discussed with more interest. Lee, T.N. and T.W. Kwon reported in 1962 the composition of free sugars in Korean ginseng was determined by use of the ion exchange chromatography and anthrone reaction. The free sugars were sucrose(8.5%), fructose(0.5%), and glucose(0.4%), Takiura, K. and I. Nakagawa reported in 1963 that seperatory determination of moncsaccharides and disaccharides contained in the aqueous extract of Ginseng Radis was carried out. As the monosaccharide, D-fructose and D-glucose where identified, the total amount of these monosaccharides in the dried root was 1.5%, disaccharides were 3.8%, and maltcse were separated as crystals. These were identified by the partition column chromatography using powdered cellulose. Peter, A.M. partially analized American ginseng (Aralia quinquefolia) roots to determine the nitrogen(1.600%), phosphoric acid (0.535%), potash(0.776%), lime(0.856%), cruce ash (5.278%) in the roots. Basic components of ginseng were known as water(66.73%), ash(1.46%), fat(0.33%), cellulose(3.67%), nitrogen(0.80%), pure protein(5.04%), soluable non-nitrogen material (22.03%), sucrose (8.53%), fructose (0.50%), glucose (0.97%), fumaric, succinic, malic, citric, tartaric, oleic, linoleic, several other fatty acids, an essential oil(probably the sesquiterpene previously named panacene), several glucosides of unknown structure and a yellow pigment. Chromosomes consist predominantly of proteins and nucleic-acid. Most important group of chromosome constituents, the nucleic acids, were discovered by the Swiss scientist Meischer in Tubingen. Nucleic acids are the carriers of genetic information. The amount of RNA and DNA in the three parts(head, trunk, tail) of each year ginseng cultivated in Kang Wha, Korea is reported few.
