The roots of Codonopsis lanceolata (Campanulaceae) contain several kinds of triterpenoid saponin with high medicinal values, which have been used in traditional medicines. This study investigates the impacts of methyl jasmonate (MeJA) -adding time on the saponin synthesis and the hairy root growth of C. lanceolata. A significant decrease in major saponin (lancemaside of three kinds) content of hairy roots was observed with MeJA treatments. Contents of lancemaside A, B and E decreased about 15%

These results suggest that MeJA treatment could be used in the production of teriterpene saponins.
