Abstract

Korean ginseng(Panax ginseng C.A. Meyer) roots have long been known as the best medicinal plant and its pharmaceutical bio-activities have been proven by scientific analyses of their components - ginsenosides, acidic polysaccharides, phenolic compounds, fatty acids and organic acids etc. Ginseng hairy roots and callus have been cultured in vitro for stable supply of ginseng material. In this study, the amount of ginsenosides, fatty acids, acidic polysaccharides, phenolic compounds and organic acids in ginseng hairy roots and callus were compared. Higher amount of ginsenoside was found in ginseng hairy roots than ginseng callus. Higher amount of saturated fatty acid (palmitic acid) was found in callus and higher amount of unsaturated fatty acid (linoleic acid) was found in hairy roots. Acidic polysaccharide and phenolic compounds were contained by the same amount in both hairy roots and callus. Organic acids were found more in hairy roots.

인삼원료삼의 안정적인 공급을 위하여 인삼의 기내배양에 의하여 생산된 캘루스 및 모상근으로부터 인삼사포닌, 지방산, 산상다당체, 페놀성화합물 및 유기산함량을 조사하였다. 인삼사포닌의 경우에는 캘루스에 비해 모상근에서 훨씬 많았으며 모상근 세포주간에는 약 10mg/g로 유사한 경향을 보였다. 포화지방산은 인삼 캘루스에서 높은 반면 모상근의 경우에는 불포화지방산이 오히려 많거나 비슷한 경향을 보였다. 특히 인삼 캘루스에서는 palmitic acid가 많이 존재하였으며, 인삼 모상근의 경우에는 불포화지방산인 linoleic acid가 캘루스의 5배 이상 많은 검출되었다. 산성 다당체와 페놀성화합물은 기내 배양한 인삼 캘루스 조직에서는 거의 동량으로 존재하였으나, 인삼 모상근의 경우에는 세포주에 따라서 많은 차이를 나타내었다. 특히 HR-2같은 경우에는 산성 다당체보다는 페놀화합물이 $2.26\%$로 산성 다당체보다 2배 이상 많이 존재하였는데 반하여, HR-3 인삼 모상근의 경우에는 산성 다당체가 $1.64\%$로 페놀화합물보다 4배 이상 존재하는 것으로 분석되었다. 인삼 모상근세포주와 캘루스의 유기산은 모상근 세포주가 34.64 mg으로 가장 많이 존재하는 것으로 조사되었다.
