Comparison of the contents of seven ginsenosides and their total content in different types of ginseng samples using t-test ((A); wild ginseng n = 2, ginseng under forest n = 27, cultivated ginseng n = 11; * p < 0.05), and the scattered plots for contents of the seven ginsenosides and their total content in ginseng under forest and cultivated ginseng with certain growing ages ((B); n = 34; contents of the seven ginsenosides in six samples—nos. 18, 19, 36–39 were not plotted due to the uncertainty of growing ages).
