Abstract

An shikonin elicitor produced by Aspergillus could affect the metabolism of Onosma cells. 12 h after the elicitor was added on the 8th day, the shikonin derivatives content, the relative content of one of derivatives-acetylshikonin,the formation of intracellular soluble protein and the consumption of sucrose increased, but cell growth was inhibited permanently. 12h after elicited treatment, the medium conductivity decreased,medium pH value increased,K~(+) flowed out and Na~(+) flowed in, showed anion transport change over membrane caused by the elicitor. At the same time the concentration of Ca~(2+) in medium increased quickly.
