“…The most common secondary metabolites determined in the above-ground parts and in the the latex of Euphorbia species are diterpenoids, triterpenoids, sesquiterpenoids, flavonoids, phenolic acids and others (WU et al, 2009;AYATOLLAHI et al, 2009;QAISAR et al, 2012). Upon testing of biological activity of E. cyparissias secondary metabolites, there were determined antimicrobial, (UPADHYAY et al, 2010;KIRBAG et al, 2013) Cypress spurge, Euphorbia cyparissias L. is a widespread species in the territory of Europe.…”

ABSTRACT. This paper presents the results of a screening of nine different extracts from the plant parts (leaves, flowers and stems) of Euphorbia cyparissias for total phenolic content, concentration of flavonoids and in vitro antioxidant activity. Мain reason for this study is the determination of these parameters and their variability among plant parts and plant extracts obtained by different solvents, respectively. Obtained amounts for total phenolic content ranged from 10.76 to 40.72 mg GA/g. The concentration of flavonoids varied from 34.32 to 134.34 mg Ru/g. The IC 50 values of antioxidant activity varied from 88.48 to 2891.08 µg/ml. Results obtained from the different plant parts were of uneven value. Great variability of the studied parameters was observed when comparing the effectiveness of the used solvents. The acetone extracts from stems contain the greatest concentrations of phenolic compounds, especially flavonoids, and showed high antioxidant activity. According to our research, plant parts from E. cyparissias can be regarded as promising candidates for natural plant sources with high value of biological compounds.

Abstract:In this study, to determine the functional subgroups of the components of Euphorbia anacampseros Boiss., which is a perennial endemic species, FTIR (Fourier Transform Infrared) spectroscopy method was adopted. The results showed that hydrocarbons particularly terpenoids, alkanes and olefin structures exist in the composition of E. anacampseros Boiss. IR spectra of E. anacampseros Boiss. samples collected at different stations screened different peak points. There is a correlation between the vibrational frequency values and the altitudes of the areas where E. anacampseros Boiss. samples were collected. This study is the first attempt in analyzing of this species by using FTIR method. Endemik Euphorbia anacampseros Boiss.'un FTIR Analiz Yöntemi ile KarakterizasyonuAnahtar Kelimeler Kurutulmuş bitki Euphorbia, FTIR spektroskopisi, Özet: Bu çalışmada, çok yıllık endemik bir tür olan Euphorbia anacampseros Boiss.'un içerdiği bileşiklerin fonksiyonel alt gruplarını belirlemek amacıyla FTIR (Fourier Dönüşümlü Kızılötesi) spektroskopi yöntemi kullanılmıştır. Araştırmamız, E. anacampseros Boiss.'un bileşiminde hidrokarbonlar, özellikle terpenoidler, alkanlar ve olefin yapılarının var olduğunu göstermektedir. Farklı noktalardan toplanmış E. anacampseros Boiss. örneklerinin kızılötesi tayfı farklı yükselme noktaları vermektedir. Vibrasyonal frekans değerleri ile E. anacampseros Boiss.'un toplandığı bölgelerin rakımı arasında karşılıklı bir ilişki mevcuttur. Bu çalışma, FTIR spektroskopi yöntemi kullanılarak bu türün incelenmesi açısından bir ilk olma özelliği taşımaktadır.
