Identification of prototypes in bio-samples, and P59 ginsenoside Rg1 is taken as an example. (a) XIC of ginsenoside Rg1 in LCD; (b) multiple XICs of ginsenoside Rg1 in bio-samples. From top to bottom: administration plasma, blank plasma, administration urine, blank urine, administration feces, and blank feces. Ginsenoside Rg1 showed the highest intensity in feces, lowest in plasma, and no response in blank samples; (c) MS/MS spectrum of ginsenoside Rg1 in LCD; (d) MS/MS spectrum of ginsenoside Rg1 in feces.
