“…The determination of volatile oil via gas chromatography has the advantages of simple operation and high sensitivity. Therefore, this paper uses and optimizes gas chromatography [ 21 , 22 , 23 ] to establish an efficient detection method suitable for MA in microcapsules. On this basis, HP-β-CD/MA microcapsules with enhanced MA solubility and stability were prepared via the spray drying method.…”

Objective: Hydroxypropyl-β-cyclodextrin (HP-β-CD)/menthyl acetate (MA) microcapsules were developed to overcome the volatile and unstable defects of MA and improve the ease of use and storage. Methods: MA microcapsules were prepared via spray drying using HP-β-CD as the wall material. The embedding rate of MA microcapsules was determined through gas chromatography. The embedding characteristics were studied using phase solubility and nuclear magnetic resonance (NMR). The stability was characterized via differential scanning calorimetry (DSC) and the release and retention rates of MA microcapsules at different temperatures. Results: The embedding rate of HP-β-CD /MA microcapsules was 96.3%. The Gibbs free energy change, enthalpy change and entropy change of the embedding reaction between HP-β-CD and MA were all less than zero, indicating that the embedding process was a spontaneous exothermic reaction. NMR spectra showed that MA entered the cavity of HP-β-CD through the large opening end and interacted with the inner wall of the small opening end. DSC and the release and retention rates of MA microcapsules at different temperatures showed that the stability of MA was significantly enhanced after being embedded in HP-β-CD. Conclusion: The HP-β-CD/MA microcapsules are able to significantly improve the stability of MA and reduce the volatilization of MA.

This study aims to measure the preventive effect of the silver, Zn oxide nanoparticles, and Camellia sinensis L. (black tea) on liver toxicity caused by the paracetamol drug. The Nanomaterials, with a practical size range of 33–40nm, black tea was extracted by Soxhlet apparatus using methanol alcohol at a concentration (80%); design in this study, 60 adult male rats weighing between 195 and 330 g and aged 11 to 14 weeks were used. They were kept in a relatively regulated setting with a temperature of 25Co at the University of Karbala’s animal facility. They received food. There were eight rat group divisions. G1: just received saline solution (0,85%) as the control. G2: 250 milligrams of black tea and 250 milligrams of paracetamol per kilogram of body weight. G3: 400 milligrams of C. sinensis L. and 250 milligrams of paracetamol per kilogram of body weight. G4: injection of 0.3 milligrams of zinc nanoparticles and 250 milligrams of paracetamol per kilogram of body weight. G5: injection of 0.5 milligrams of zinc nanoparticles and 250 milligrams of paracetamol per kilogram of body weight. G6: injection of 0.3 milligrams of silver nanoparticles and 250 milligrams of paracetamol per kilogram of body G7: injection of 0.5 milligrams of silver nanoparticles and 250 milligrams of paracetamol per kilogram of body, G8: 250 milligrams of paracetamol per kilogram of body administered intravenously, the blood bled for 30 days after receiving all dosages orally once daily for 21 days. When rats were given injections of 0.5 mg of nanoparticles and when injections of 250 mg of a black tee., it was discovered that the concentration of Malondialdehyde MDA, Lipid Peroxidation LPO, Triacylglycerid, cholesterol levels, and glucose decreased significantly. In contrast, Glutathione peroxidase GPX and protein levels are increased considerably. This was due to the injections’ preventive and antioxidant action against the oxidative stress brought on by the paracetamol height dose. Keywords: silver nanoparticles, Zn oxide nanoparticles, Camellia sinensis L., paracetamol.
