title: Triterpenoid Saponins from Primula denticulata.
abstract: Two triterpene glycosides denticin ( 1) and denticulatin ( 2) have been isolated from the whole plant of PRIMULA DENTICULATA Sm. and their structures were established by spectral and chemical studies as 3beta-{ O-beta- D-glucopyranosyl-(1-->4)-[ O-beta- D-xylopyranosyl-(1-->2)]- O-(beta- D-glucopyranosyl-(1-->4)-[ O-beta- D-glucopyranosyl-(1-->2)]-alpha- L-arabinopyranosyloxy}-16alpha-hydroxy-13beta, 28-epoxyolean-30-al and 3beta-{ O-beta- D-glucopyranosyl-(1-->2)- O-beta- D-glucopyranosyl-(1-->4)-[ O-beta- D-xylopyranosyl-(1-->2)]- O-beta- D-glucopyranosyl-(1-->4)-[ O-beta- D-glucopyranosyl-(1-->2)]-alpha-L-arabinopyranosyloxy}-16alpha-hydroxy-13beta,28-epoxyolean-30-al, respectively.
