Two new dammarane‐type triterpenoidal saponins, notoginsenosides FP 1 ( 1 ) and FP 2 ( 2 ), were isolated from the fruit pedicels of Panax notoginseng , along with 22 known compounds. Their structures were elucidated on the basis of spectroscopic evidences and chemical methods. The known compounds were identified as ginsenosides Rg 1 ( 3 ), Re ( 4 ), Rb 3 ( 5 ), Rc ( 6 ), Rd ( 7 ), Rb 2 ( 8 ), Rb 1 ( 9 ), F 2 ( 10 ), and F 1 ( 11 ); as notoginsenosides R 1 ( 12 ), Fa ( 13 ), and Fc ( 14 ); as vina‐ginsenoside R 7 ( 15 ); as gypenosides IX ( 16 ), XVII ( 17 ), and XIII ( 18 ), and as chikusetsusaponin‐L 5 ( 19 ), quercetin 3‐ O ‐ β ‐ D ‐glucopyranosyl‐(1→2)‐ β ‐ D ‐galactopyranoside ( 20 ), kaempferol 3‐ O ‐ β ‐ D ‐glucopyranosyl‐(1→2)‐ β ‐ D ‐galactopyranoside ( 21 ), benzyl‐ β ‐primeveroside ( 22 ), ( S )‐tryptophan ( 23 ), and icariside B 6 ( 24 ). Compounds 15, 19 and 22 – 24 are reported for the first time from the title plant.
