Pharmacognostical Study on Euphorbia ebracteolata(II) -On the chemical study of the tannins and related compounds-

Euphorbia ebracteolata에 대한 생약학적 연구(II) -Tannin 및 관련화합물에 관한 화학적 연구-

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.
