INVESTIGATION OF SOME ACTIVE CONSTITUENTS OF EUPHORBIA BIVONAE STEUD

The investigation of some active constituents of Euphorbia bivonae included terpenes, alkaloids, coumarins and anthraquinones to evaluate its economic values as medicinal plant, where sugiol and betulin compounds were isolated from the aerial parts and roots of Euphorbia bivonae, while ferruginol compound was isolated only from the roots. The total terpenes content of the aerial parts and roots of E. bivonae were 3.44 and 8.96 mg/g, respectively, which were estimated spectrophotometrically. Meanwhile, the compounds 2Piperidinone, N[4bromonbutyl] and komaroine were isolated from the aerial parts and roots of E. bivonae. While the alkaloid compounds 5,8-dihydroxy methyl-canthin-6-one and 1-methoxy-8-hydroxy-methyl-canthin-6-one were isolated from only the roots. The estimated percentages of the total alkaloids were 0.40% and 1.02% for the aerial parts and roots, respectively. The coumarin compound umbelliferone was isolated from the aerial parts and roots, and the total coumarins content of the aerial parts and roots were 0.42 and 0.49 mg/g, respectively. On other hand anthraquinone compound emodin (1, 3, 8-trihydroxy-6-methyl-9, 10 anthracenedione) was detected and isolated from the roots only, meanwhile the concentrations of total anthraquinones were 0.04 and 0.94g/100g dry material for aerial parts and roots, respectively. Key words: Euphorbia bivonae, terpenes, alkaloids, coumarins and anthraquinones.
