In this study, DNA protective, antioxidant, antibacterial and enzyme inhibiting properties of methanol extracts obtained from juniper and olive heartwood and sapwood were determined. These extracts were tested by five antioxidant methods (DPPH scavenging, FRAP, CUPRAC, metal chelating and phosphomolybdenum). Generally, heartwood extracts of both species are more efficient for DPPH radical scavenging activity, cupric ion reducing activity, ferric reducing antioxidant power and metal chelating activity than sapwood extracts. When compared to heartwood extracts, sapwood extracts have larger inhibition zone in disk diffusion test. In addition, all extracts showed high antibacterial activity against Staphylococcus aureus. DNA protection of both extracts had a capacity to inhibit the DNA damage arisen from Fenton's reagent. The highest DNA protective activity was observed in juniper sapwood extract with 84%. Furthermore, other extracts also indicated more than 60% of DNA protective activity. Olive wood extracts displayed the strongest enzyme inhibition activities against acetylcholinesterase (AChE) and butyrylcholinesterase (BChE). Although juniper heartwood extracts showed highest anti-amylase, anti-glucosidase and anti-tyrosinase effects, they had no ability for inhibition BChE.The methanol extracts of olive samples demonstrated the most antioxidant activity (DPPH, CUPRAC and FRAP). In addition, juniper samples showed the highest anti-amylase, anti-tyrosinase, metal chelating and DNA protective activity. According to these results, the extracts of juniper and olive wood can be considered as a source of natural bio active agents for dietary, pharmacological and medicinal applications. This research will also serve as a base for future studies about biological activities of wood extracts.

In this study, the cold press oil components and antimicrobial activities of fennel (Foeniculum vulgare) and anise (Pimpinella anisum) and white mustard (Sinapis alba) and black mustard (Brassica nigra) species seeds, which are widely used by the people for alternative medicine, were determined. F. vulgare, P. anisum, S. alba and B. nigra species seeds were obtained from cultivated areas in central Anatolia in Turkey. The oil was extracted by using a screw press (MP-001 Cold Press, Turkey), and the volatile oil components and fatty acid components in these oils were analysed by GCMS and total phenolic content, total flavonoid content and antioxidant activities by DPPH and FRAP (%) method were determined. Antimicrobial activities of obtained oils were investigated by using minimum inhibitory concentration (MIC) test by against 18 different species microorganisms. In the GCMS results, F. vulgare and P. anisum oils were found to be the most abundant components which were anethole (89.74%, 88.95%, respectively). According to these results, the plants oils didn't show any antimicrobial activities against tested microorganisms. However especially white and black mustard oils showed strong antioxidant activity when compared with artificial antioxidants.

Introduction Juniperus communis L. is a wood species used in folk medicine since it has a variety of wood extractives with a wide range of pharmacological properties. The morphological features of juniper wood structure leads to the necessity for the application of activation, which facilitates extraction of wood extractives. The methods of thermochemical activation can be used to improve the existing schemes of extraction. Objective This work aims to develop methods that increase the selectivity and efficiency of the extraction of pharmacological biologically active substances from the Juniperus communis wood. Methodology The thermochemical activation of the juniper wood matrix involves treatment by steam explosion and the use of supercritical fluid extraction methods. Gas chromatography mass spectrometry analysis was used to identify the components of the obtained extracts. Results It is shown that the supercritical fluid extraction by a binary solvent facilitates the extraction of the maximum amount of sesquiterpene and diterpene alcohols, terpene oxides and ketones. Extracts obtained during the two‐stage process with the traditional extraction in a Soxhlet apparatus at the first stage and the supercritical fluid extraction at the second, contain squalene as the main component. The two‐stage treatment with steam explosion at the first stage facilitates the extraction of the maximum amount of diterpene alcohols having the widest range of biological activity. Conclusion The research demonstrates the prospects of application of the methods of thermochemical activation of plant raw materials for the extraction of the wide spectrum of terpene components.
