P. ginseng (1 g) was dissolved in 90% methanol and subjected to HPLC. The column was eluted with solvents A (18% acetonitrile) and B (80% acetonitrile) at a flow rate of 1.6 ml min–1. The following solutions were used: 100% A and 0% B changed over 32 min, 80% A and 20% B to 80 min, 0% A and 100% B to 100 min and 100% A and 0% B to 110 min.
