Chemical structures and representative HPLC chromatograms of PTS. 2D Chemical structure of a ginsenoside Rg₁, b notoginsenoside R₁ and c ginsenoside Re. d HPLC chromatogram of Panaxtriol Saponins (Lot No.:20190318) and the content of Rg₁, R₁ and Re. e HPLC chromatogram of reference standard and the percentage of each reference. Difference in structures of the above three compounds were shown in blue or red. The determination method was based on the Chinese pharmacopoeia 2015 and the absorbance at 210 nm was monitored by HPLC
