  • A chemical examination of the aerial parts of Euphorbia pekinensis $R_{UPRECHT}$. (Euphorbiaceae) has led to the isolation of seven hydrolyzable tannins and ten fl avonoid glycosides. The former ones have been identified as gallic acid, methylgallate, 3-O-galloyl shikimic acid, 1,3,4,6-tetra-O-galloyl-${\beta}-_D$-glucose, 1,2,3,4,6-penta-O-galloyl-${\beta}-_D$-glucose, corilagin, geraniin and the latter ones as isoquercitrin, quercitrin, astragalin, afzelin, prunin, rutin, kaempferol-3-O-rutinoside, quercetin-3-O-(2"-O-galloyl)-${\beta}-_D$-glucoside and quercetin-3-O-(2"-O-galloyl)-${\alpha}-_L$-rhamnoside on the basis of chemical and spectroscopic evidence.

  • Seven hydrolysable tannins and two related compounds have been isolated from the acetone-water(4 : 1) soluble portion of the aerial parts of Euphorbia ebracteolata(Euphorbiaceae). Seven hydrolysable tannins have been determined as 3-O-galloyl-shikimic acid, 1, 3, 4, 6-tetra-O- and $1,\;2,\;3,\;4,\;6-penta-O-galloyl-{\beta}-D-glucose$, corilagin, tercatain, punicafolin and geraniin and two related compounds determinedasgallicacidandellagicacidonthebasisof spectral data and physico-chemical evidence.
