| 摘 要： | 对水母雪莲细胞悬浮培养过程中细胞生长、黄酮积累和底物消耗的动力学过程进行了研究.经15 d液体培养可获得最大生物量干重和黄酮产量分别为17.2 g·L-1和607.8 mg·L-1,通过调控基本培养基种类和有机添加物可提高雪莲细胞的生长和黄酮积累.获得的水母雪莲细胞培养物具有明显的抗氧化活性,其抗氧化活性与雪莲细胞中的黄酮含量相关. |

| Abstract: | The kinetic processes of cellular growth,flavonoid accumulation and substrate consumption in the suspension culture of Saussurea medusa cells were studied,which showed that the highest dry biomass and flavonoid yield occurred after 15-day culture amounting to 17.2 g·L-1 and 607.8 g·L-1,respectively,and the adjustment of the medium kinds and the addition of organic additives could increase the growth and flavonoid accumulation of Saussurea medusa cells.In the culture of Saussurea medusa cells,the antioxidant activities appeared very remarkable and related to flavonoid yield in Saussurea medusa cells. |
| Keywords: | Saussurea medusa flavonoid suspended cells antioxidant |
