Special Issue Information

Dear Colleagues,

Phytochemicals are bioactive substances synthesized by plants to protect them against external factors. In addition, they determine color and aroma and influence the regulation of their growth. Phytochemicals also have other beneficial properties: bactericidal, fungicidal, insecticidal and antioxidant. The antioxidant properties are related to their chemical structure and are responsible for, among others, neutralizing free radicals, which means that they can directly affect the human body. Their protective and healing effects can be used to fight many diseases, including oxidative stress. Due to these properties, phytochemicals should be important components of the diet. Therefore, progress in techniques for the effective isolation of these compounds is very important. From traditional solvent extraction methods to innovative approaches, researchers continually strive to optimize extraction efficiency, selectivity and sustainability. By improving extraction techniques, researchers can effectively analyze these compounds qualitatively and quantitatively.

The aim of this Special Issue is to present the latest developments in phytochemical extraction techniques. By contributing to this Special Issue, you will contribute to the development of extraction methods, improving the identification, characterization and determination of phytochemicals for their effective use in human life. We look forward to your contributions and support for meaningful discussions in this important area of research.

Sea buckthorn berries (SBB) are well known for being rich in natural bioactive compounds with high pharmacological activity. In this study, the optimization of extraction parameters was performed to recover phenolic compounds with high antioxidant activity from SBB. This study involved a systematic optimization approach, including screening for a variety of parameters, including temperature, time, ethanol concentration, agitation, and solid loading. On the basis of Plackett–Burman design (PBD) model, the two most significant parameters (agitation and solid loading) were selected, and the correlation model between those parameters and multiple responses was derived via response surface methodology (RSM). As a result, the optimal extraction condition for maximizing phenolic content and antioxidant activity was determined to be agitation at 109.54 rpm and a solid loading of 172.67 g/L. Under optimal conditions, SBB extract showed a total phenolic content of 0.21 mg/mL and ABTS and DPPH activities of 27.27% and 58.16%, respectively. The SBB extract prepared under optimal conditions was found to contain caffeic acid, vanillic acid, rutin, and vitamin B1 (thiamine). This work is the first challenge to design an optimization model for the efficient recovery of antioxidants from SBB and is significant in that the model can be applied simply and economically to conventional extraction processes.
