Abstract:
Objective To establish the suspension cell line of Atractylodes lancea and to study the effect of two endophytic fungal elicitors on its essential oil production.Methods The essential oil was extracted by using ultrasonic wave after suspension cell was treated with endophytic fungal elicitors.Then,the determination of four compounds(atractylone,hinesol,?-eudesmol,and atractylodin) was carried out by gas chromatography.Results By testing in various conditions,the suspension cell line with a rapid growth rate was established.Its highest biomass(6.95 g/L) was obtained on day 21.?-Eudesmol was the only detection in the control suspension cell,and its highest content(17.469 ?g/g) was also reached on day 21.The effect of crude elicitors of two endophytic fungi(belong to Cunninghamella sp.and Gilmaniella sp.respectively,named AL4 and AL12) on the cell growth and the production of essentia1 oil were investigated.Overall AL4 elicitor got better effect.When suspension cell of 14-day-old cultures was exposed to AL4 elicitor(carbohydrate 20 mg/L medium) for 7 d,the biomass increased 3.31% over the control,and the four compounds(atractylone: 14.715 ?g/g,hinesol: 28.395 ?g/g,?-eudesmol: 38.794 ?g/g,and atractylodin: 8.310 ?g/g) were all detected.Among them,the content of ?-eudesmol reached 2.22 times as much as the control.Conclusion The cell growth and the accumulation of essential oil of A.lancea could also be promoted by adding crude elicitors of the endophytic fungi AL4 and AL12.
