The results show that the duration of the 3 phases during the culture of cell suspension is related to the inoculum size, the initial nutrient concentration, the feeding of nutrients and the culture conditions such as temperature and dissolved oxygen, that the maximum cell yield reaches about 12g/L for batch culture or 35g/L for fed-batch culture in dry weight, that the saponin content of cells quickly increases in the bloom phase and keeps on increasing until the early stage of the declining phase, with a maximum saponin content of about 60~70g/kg in dry weight, that the conductance value of cell suspension decreases from more than 8000μS to less than 600μS with the growth of cells, but increases when the cells autolyze, and that part of cells turns red in the later culture, which has no apparent effect on the saponin content.

结果显示：细胞3个生长时期的持续时间与接种量、初始营养浓度、营养流加情况及培养条件有关；分批培养和流加培养时的最大细胞得率分别为12g/L和35g/L；细胞的皂甙含量在旺盛生长期快速上升，并保持增长至衰退期前期；干细胞中最大的皂甙含量达60~70g/kg；随着细胞的生长，培养液的电导值从8000μS以上下降至600μS以下，细胞自溶后逐渐回升。另外，培养后期部分细胞颜色变红，但没有发现颜色转变对皂甙含量造成影响。
