    Abstract In the setting of healthcare, the use of hand sanitizers and antiseptics for hand hygiene is of paramount importance to avoid transfer of pathogenic microorganism through hand and skin contact. There is an increasing interest in the incorporation of essential oils in hand sanitizer's formula to avoid the adverse effect of conventional hand sanitizers on health. This study aimed to detect the chemical constituents of citrus peel essential oils and study their antimicrobial activity compared with commercial hand sanitizers. The qualitative and quantitative analysis of the hydrodistillated essential oils of peels of grapefruit (

    Abstract The present study focused on evaluating the proximate analysis, mineral composition, and in vitro anti-giardial activity of Pimpinella anisum seed extracts, which are aromatic plants with a long history of usage in folk and conventional medicine, as well as pharmaceutical manufacturing. Standard methods were used to determine the proximate analysis of the powdered plant sample, including dry matter, ash, fat, protein, fiber, and carbohydrates. The mineral contents of Pimpinella anisum seed were analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS), revealing that the plant has a high fiber content (42.62%) followed by carbohydrates (38.79%). The seeds were also found to be a rich source of minerals, with notable amounts of Rubidium, Magnesium, and Calcium. The extracts showed a high mortality percentage compared to Metronidazole, with the chloroform extract exhibiting higher anti-giardial activity (78.71%) than the ethanolic extract (75.29%) at a concentration of 500 ppm. These findings support the traditional use of Anise in treating gastrointestinal issues and as a natural supplement. Further studies are needed to isolate the active ingredients and understand their mechanism of action.

    Abstract SARS-CoV-2 is a new strain of coronavirus that appeared in China in December 2019, in recent years, great progress has been made in developing new antiviral drugs, and natural products, are important sources of potential and new antiviral drugs. The present study aimed to assess some biologically active compounds present in medicinal plants as potential COVID-19 inhibitors, using molecular docking methods. The Docking study was performed by Molecular Operating Environment software (MOE). About 20 Compounds were screened in this study; these compounds were selected based on classification of their chemical origin and their antiviral activity from literature. These compounds might be used to inhibit COVID-19 infection. The results demonstrate the effectiveness of this screening strategy, which can lead to rapid drug discovery in response to new infectious diseases. The results showed that many compounds isolated from medicinal plants such as; Gallic acid (- 17.45), Quercetin (- 15.81), Naringin (- 14.50), Capsaicin (- 13.90), and Psychotrine (- 13.5) are important sources for novel antiviral drugs targeting COVID-19.

    Abstract The use of nanoparticles in medicine, nanomedicine, is very important to diagnose and treat diseases; among the various metallic nanoparticles, silver nanoparticles (AgNPs) are very popular due to their physical, chemical, and biological properties, encompassing a range of activities such as antiviral, antifungal, anti-inflammatory, and anticancer activities. In this study, the synthesis of AgNPs was conducted by the use of a nontoxic, ecofriendly method. Green tea (GT) leaf extract was used as a reducing agent to convert silver ions into free AgNPs. The UV-vis spectrum showed a peak at 410 nm, confirming the presence of AgNPs. A Fourier-transform infrared (FTIR) analysis of the GT extract and GT AgNPs display spectra that is identical to those of polyphenols, polysaccharides, and proteins. All the vibrational peaks in the GT extract spectrum were shifted in the AgNP spectrum, becoming narrower after the encapsulation of nanoparticles. The scanning electron microscopy (SEM) images confirm the presence of AgNPs with different sizes, ranging from 15 to 33 nm. Furthermore, the antibacterial activity of the synthesized AgNPs in three different concentrations (10, 20, and 50 mg ml
