Abstract:
Object To investigate the application of cell immobilization culture to producing ginkgolides in Ginkgo biloba L. Methods To immobilize the cells by polyaminoresin foam as support materials, and determine the effects of different factors. Results The results showed that 71% of immobilization ratio and 22 mg/cm 3 of cell density were obtained using P29 of high density, small bore diameter with pieces of 0.5 cm ? 0.5 cm ? 0.5 cm, 0.72 g of support matrices per bottle in 65 mL of MS medium solution supplemented with 2,4-D 8.0 mg/L+KT 0.04 mg/L+NAA 0.4 mg/L and the incoulum quantity was 200 g/L. Conclusion It shows that present method has some advantages, such as simpleness, low cost, high immobilization ratio.
