참돌꽃 (Rhodiola sachalinensis A. Bor) 캘러스에서 elicitor와 전구체에 의한 Salidroside 생산성의 변화

초록

The effect of elicitor and precursor on salidroside production from Rhodiola sachalinensis A.Bor callus cultures was investigated. Callus cultures were treated with yeast extract, soft-ferrite ceramics powder, methyl jasmonate, ascorbic acid, jasmonic acid and CuCl2/CdCl2 as an elicitor. When callus cultures were treated with 0.2 g/ℓ of yeast extract, salidroside production from callus treated with yeast extract is 3.45 times higher than that of the controlled group. Among of them, callus cultures treated with yeast extract produced the highest salidroside. Callus cultures were treated with L-phenylalanine and L-tyrosine as a precursor for 4 days. The result of salidroside content analysis showed that all feeding of precursors not affected salidroside production from callus cultures. In case of L-tyrosine fed into callus cultures, both callus growth and salidroside production decreased at all concentrations.
