title: [Regulation of fungal elicitors on the cell growth and biosynthesis of saponin of Panax ginseng cell suspension culture].
abstract: Adding fungal elicitors to the Panax ginseng cell suspension cultures, the biosynthesis of saponin was obviously induced, the total productivity of saponin in cultures could increase more than 30% of the control. During elicitation, the accumulation patterns of saponin in suspension cultured cells were changed, the culture time for maximum biosynthesis of saponin was shortened 2-4 days comparing with that of the control, and about 80% of biosynthetic saponin in elicited cells was secreted into medium, meanwhile the uptake for sucrose in medium of cells was enhanced, and the disturbing of pH in medium was observed, which predicated that an ion exchange occurred between elicited cells and medium.
