Single extraction

Pluchea pteropoda, an annual plant in the Asteraceae family, has traditionally been used in Vietnamese folk medicine as an alternative treatment for high fever, indigestion, and painful and swollen wounds. The present study investigates the acute toxicity and antiinflammatory effects of P. pteropoda aerial parts ethanol extract (EtPP) in animal models. EtPP exhibited no toxicity in mice with a single dose of up to 5000 mg/kg.

In our study, the mixture of cellulase and pectinase were used to exploit plant matrix. The combination of these enzymes increased the extraction efficiency compared to single enzyme treatment. The fresh tea leaves, byproduct of the green tea processing, were utilized as materials for extracting. And the enzyme-assisted extraction was investigated. Firstly, the materials were treated with the mixture of cellulase and pectinase.

In this research, a single-step polymeric novel particle was synthesized from oak bark extract by nanoemulsion polymerization technique for the first time in the literature. It has been shown that the synthesized particles are achieved without losing any antioxidant and antibacterial properties of the oak bark extract. In this study, the p(OB) particles were reported for the first time and were characterized in terms of antioxidant, blood compatible, H2O2 scavenging, antibacterial, and antifungal potential to evaluate their use in biocompatible materials with drug release system potential.

Tetrodotoxin analogues (TTXs) have been broadly applied in many fields. Viscera of pufferfish from Viet Nam was reported to contain a high level of TTXs, indicating a promising source for isolation of TTXs. In this work, critical factors affecting TTX recovery yield from pufferfish viscera collected from fishermen in the Can Gio coast of Viet Nam were optimized using response surface methodology (RSM).

It is very important to develop a process for selectively extracting Zr(IV) ions from the solution medium to produce zirconium metal used in industry and nuclear reactors. In this study, the parameters affecting the extraction of Zr(IV) ions were investigated using a multidropped liquid membrane (MDLM) system. Trioctyl amine (TOA) dissolved in kerosene was used as a carrier ligand in the extraction of Zr(IV) ions by the MDLM technique.

The timing of the deposition of the well-preserved Quaternary marine terraces in the coastal region of northeastern Turkey are crucial in understanding the Quaternary tectonics of the Pontides. The chronology of raised marine terraces between Trabzon and Rize has remained unrevealed because of chronologic limitations. This study aims to establish chronology for the terrace deposits by applying optically stimulated luminescence (OSL) dating methods using single aliquot regenerative dose (SAR) techniques on quartz grains extracted from marine terraces.
