To select pharmaceutically characteristic strains of Glycyrrhiza species, MeOII extracts of 168 Glycyrrhiza leaf samples from 43 medicinal plant research stations in Japan were analyzed by HPLC. Apparently, one type of G. uralensis, 4 types of G. glabra and one type each of G. echinata, G. pallidiflora and G. foetida have been grown in these stations. The MeOH extracts of leaves containing twigs of these species provided the reproducible HPLC patterns. Seventeen constituents were isolated and identified on the basis of the spectral data as vicenin 2, schaftoside, rutin, isoquercitrin, kaempferol-3-O-rhamnosylgalactoside, nicotifiorin, narcissin, astragalin, cacticin, ononin, pinocem- brin, genistein, licoflavanone, hydroxywighteone, lupiwighteone, sigmoidin B and wighteone. HPLC profiles of these compounds may be useful for identification of the species of Glycyrrhiza plants.
