The antioxidant extracts considered a very important food additive which promoting the protection of lipid and prolong the shelf life of food products. The aim of this investigation was decrease the time of extraction of hibiscus leaves extract (HLE) and olive leaves extract (OLE) from 48 h to only 6 h without reducing efficiency of these extracts. HPLC assay, scavenging radical activity by DPPH˙ (IC), inhibition lipid peroxidation by both β-Carotene/Linoleic Acid Bleaching (βCB) and Thiobarbituric Acid Reactive Substances (TBARs) assays, antibacterial and antifungal activities measured for different concentrations of ethanolic extracts by conventional extraction (CE) and difference in pressure extraction (DPE) methods, and the results shown a considerable in mean difference ( < 0.

Lemongrass (Poaceae) is one of the aromatic plants with strong odors. Traditionally, lemon grass oil has been used for the treatment of many diseases such as gastrointestinal cramps, high blood pressure, high body temperatures, and fatigue, and is also considered an antibacterial and anti-diarrheal agent. Therefore, this study aims to investigate volatile active constituents and a few important biological activities of the volatile oil of lemongrass (Cymbopogon citratus) grown in Oman.

Post-harvest losses and rapid fruit ripening at room temperature are major challenges in preserving fruit quality. This study aimed to reduce such losses by applying a red carotenoid pigment, bacterioruberin extracted from an sp. The carotenoid was characterized as bacterioruberin and its derivative tetra anhydrous bacterioruberin (λmax 490 nm), and an / value of 675 and 742 (M+ 1H).

Among individuals who wear removable dentures, there is a significant likelihood, reaching up to 70 %, of experiencing a condition known as denture-induced stomatitis. To address this issue, a commonly used method involves soaking dentures in denture cleansers to eliminate microorganisms. However, the prolonged use of this cleaning method has resulted in the emergence of drug resistance.

Oral ulcers are prone to recurrence and often complicated by bacterial infections. Currently, antibiotics, glucocorticoids, and anesthetics are commonly employed in clinical practice to alleviate symptoms. However, these medications exhibit limited retention in the moist and dynamic environment of the oral cavity, and their long-term use may lead to various side effects or drug resistance.
