Figure 1

The HPLC analysis of the extract of Panax notoginseng. (A) Exact of PN; (B) notoginseng formula particles (allowed for using in clinic, Lot: A1500376); (C) standards sample (Ginsenoside Rg1, Ginsenoside Re, and Ginsenoside Rb1); (D) standards sample 2 (Ginsenoside Rd); (E) standards sample 3 (Notoginsenoside R1). Notoginsenoside R1 (1) was detected at approximately 33.001 minutes, Ginsenoside Rg1 (2) was detected at approximately 39.175 minutes, Ginsenoside Re (3) was detected at approximately 40.632 minutes, Ginsenoside Rb1 (4) was detected at approximately 88.182 minutes, and Ginsenoside Rd (5) was detected at approximately 107.994 minutes. They are hard to be completely purified.
