지치 세포 배양에 의한 시코닌계 색소생산

Production of shikonin derivatives through cell suspension culture of Lithospermum erythrorhizon was investigated. Optimal concentrations of IAA and kinetin on the growth of cell suspension were 0.2 and 0.1 ppm respectively. Pigment content was markedly increased when aluminum oxide was added to the production medium and its optimal concentration was 1.5g/70ml medium. The most effective concentration of IAA was 0.5 ppm and the production of pigment did not depend on the kinetin concentration.
