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 ofEuphorbia 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-Larabinofuranoside (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, 1H and 13C 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.
