title: The growth characteristics and ginsenosides isolation of suspension-cultured crown gall of Panax quinquefolium.
abstract: The growth characteristics and ginsenosides isolation of the suspension-cultured crown gall of Panax quinquefolium were studied. The result showed that the maximum biomass of cultures was 18.6 g/L (dry weight) and the content of ginsenosides reached its maximum level of 620.4 mg/L on the 27th day. The utilization rates of sugar, phosphorus, nitrogen in NH4+ and nitrogen in NO3- were 91.8%, 100%, 81% and 97%, respectively. Four compounds were isolated from the suspension-cultured crown gall and their structures were elucidated as pseudoginsenoside F11 (I), ginsenoside Rd (II), ginsenoside Rb1 (llI) and ginsenoside Rb3 (IV).
