Compositional Diversity

Present study reports a comparative screening of three ecotypes of Ziziphora tenuior L., sampled from three region with different elevation in middle and northeastern Turkey, based on their essential oil composition, total phenolic content and antioxidant capacities. Z. tenuior ecotypes showed twenty compounds, representing 89.18-91.44% of the essential oil (EOs) identified by GC-MS. The major components of EOs in ecotypes were pulegone (37.23-49.12%), and followed by 1,8-Cineole (2.26-7.78%), limonene (4.20-5.44%), ?-Caryophyllene (3.88-5.11%) and thymol (2.68-4.11%), respectively. Ecotypes showed variable pulegone content and it was increased with elevation increase. The total phenolic contents varied among ecotypes ranged from 21.13 to 27.50 mg of gallic acid equivalent/g EOs. Antioxidant capacity was determined in vitro using DPPH radical-scavenging and FRAP (Ferric reducing power) assays and expressed as concentration of each extract required to inhibit radical by 50% (IC50 and EC50) values that ranged from 0.80 to 0.97 mg/ml in DPPH and 0.42 to 0.55 mg/ml in FRAP assays, respectively. Our results indicated that antioxidant capacity changed among ecotypes. Taking into account the essential oil content, it seems that to select ecotype was the most appropriate to obtain more pulegone for this plant from its wild habitat.

Satureja x delpozoi is a hybrid found in southeastern Spain, in a population in which both parents S. intrincata and S. obovata are found together. This work presents for the first time the volatile profile and antioxidant activity of the essential oils of this hybrid. The volatile profile of the essential oils from S. x delpozoi underlines the hybrid character of these plants since the p-cymene, γ-terpinene, camphor and thymol concentrations in hybrid 1, and the same components, along with α-terpineol concentrations in hybrid 2, showed intermediate values with respect to the values observed in the parents. As regards the antioxidant capacity, the phenolic content of S. intrincata resulted in its essential oil having the greatest activity against the DPPH. and ABTS+ radicals. Both hybrids showed low activity against these radicals, although S. obovata showed none. On the bases of their essential oil composition and antioxidant capacity, these results corroborate the hybrid character of these two S. x delpozoi plants.
