    Abstract:
    OBJECTIVE: To observe the effects of a biotic elicitor fungal hyphae extract, an abiotic elicitor methyl jasmonate and their synergistic action on the accumulation of phenolic acids and tanshinones in Salvia miltiorrhiza hairy root. METHOD: Different elicitors were added to S. miltiorrhiza hairy root, which was subcultured for 21 days, the dry weight and contents of phenolic acids and tanshinones were determined at different harvest-time. RESULT: S. miltiorrhiza hairy root growth was significantly inhibited by all three treatments and the accumulation of cryptotanshinone and dihydrotanshinone were promoted by each elicition. As for the accumulation of phenolic acids, there were differences between fungal elicitor and methyl jasmonate treatments, they were promoted by methyl jasmonate while inhibited in a certain extent by fungal hyphae extract. CONCLUSION: Fungal elicitor, methyl jasmonate and their synergistic action have significant influence on accumulation of components in S. miltiorrhiza hairy root, and the effect varies between phenolic acids and tanshinones. There is no correlation between production of water-soluble ingredients and fat-soluble components on the whole under three different treatments.
