Enhancement of ajmalicine production in Catharanthus roseuscell cultures with methyl jasmonate is dependent on timing and dosage of elicitation


The optimum growth stage for enhancing ajmalicine production in Catharanthus roseuscultures with methyl jasmonate (MJ) was after 6 d growth. MJ added at 10 or 100 μm on day 6 gave a maximum ajmalicine production of 10.2 mg l−1, a 300% increase over that of non-elicited cultures.
