%X In order to investigate the effects of fungal elicitor and macroporous adsorption resin on shikonin accumulation in hairy roots of arnebia euchroma (Royle) Johnst, we used spectrophotometry to determine the total naphthoquinone content of the hairy roots, by adding different volume ratio of Aspergillus niger elicitor, Aspergillus oryzae elicitor, and the macroporous resin into the M-9 liquid medium at different culture time. The results show that the total naphthoquinone content was 2.28 times higher than the control when we added mixed elicitors of Aspergillus niger and Aspergillus oryzae at the ratio of 2.5:50 in the 10th day of hairy roots cultivating. The total naphthoquinone content was 3.71 times higher than that of the control, when we added macroporous adsorption resin NKA-9. Aspergillus niger elicitor exhibited synergistic effect with Aspergillus oryzae elicitor to enhance the naphthoquinone. Also, the total naphthoquinone level was 4.17 times higher than that of the control by adding mixed fungal elicitor and macroporous adsorption resin NKA-9 in the bioreactor. Aspergillus oryzae and mixed elicitor could promote the hairy roots proliferation, and macroporous adsorption resin NKA-9 and mixed elicitor increased the total naphthoquinone content. In summary, the measure developed for Arnebia euchroma (Royle) Johnst hairy roots cultivating in bioreactors may potential for large-scale production of naphthoquinone.
