Studies of some Euphorbia species seed flavonoids in Markazi Province

Euphorbia is one of the largest genera in Euphorbiaceae with more than 2000 species in the world and about 100 species in Iran. In this study seed flavonoids of 13 collected Euphorbia species from different part of Markazi Province were investigated. Aqueous-ethanolic extracts of seeds were examined to practice flavonoid detection، isolation and identification by 2-Dimensional Paper Chromatography (2-DPC)، Thin Layer Chromatography (TLC) and available references. Voucher specimens of each sample were prepared for reference as herbarium vouchers. Qualitative data were encoded and analyzed with quantitative data by Pricipal Component Analysis (PCA) using the SPSS. Results showed some phytochemical characters such as total number of flavonoids، kaempherol، quercetin، myricetin، flavone and dihydroflavonol glycoside are valuable for chemotaxonomy and their usage.
