Phytochemical Screening on Euphorbia milii Red Flowers – Isolation of Terpenoids, Flavone and Phenols

Objective: To learn the phytochemical screening of terpenoids, flavone and phenols from different extracts of Euphorbia milii Red flowers. Materials and Methods: Euphorbia milii (Euphorbiaceae) is an ornamental plant plays a role in folk medicine. The Chinese use it as a cure for cancer, and some Brazilians believe that it can cure warts.The flowers were extracted with the three different solvents like petroleumether, ethyl acetate and 70% ethanol &the yield were found to be 21 g, 15 g and 12 g respectively, concentrations of 50 % and 100% ethanol respectively. Results: Two triterpenoids, Taraxerol (1), 28-hydroxyfriedelan-1,3-dione-29-oic acid (2) as well as one flavone, Quercetin 3-O-(2"-O-galloyl)-a-L-arabinofuranoside (3) and two phenoilccompounds, 7 7'- dihydroxy, 8, 6'-bicoumarin (4), 9-acetyl-3'4'-dimethoxy dehydroconiferyl-3-alcohol (5) were isolated for the first time from the flowers of Euphorbia milii . The structures of the isolated compounds (1–5) were realized on the basis of the spectral data (IR, 1 H and 13 C NMR and mass ). Conclusion: The obtained compounds of Euphorbia milii flowers are effective pharmaceutical compounds which will serve as a better alternative to chemical based pharmaceuticals.
