Methicillin-resistant Staphylococcus aureus (MRSA) infections are prevalent in hospitals and often lead to significant health complications. This study aimed to explore the chemical composition of the aerial part of Crotalaria madurensis and evaluate its antioxidant and antibacterial properties. The impact of gamma irradiation on the antibacterial...

Cymbopogon proximus comprises several phytoconstituent classes that are reported to possess anticancer activity; however, studies on the anticancer potentials of the plant are lacking. C. proximus was extracted using solvents with increasing polarity. In-vitro cytotoxic activity of C. proximus extracts was examined against liver (HepG2), lung (A549...

Numerous polyphenolic compounds originating from plants are thought to have anticancer and apoptosis-inducing effects on cancer cells. Plumeria rubra (family Apocyanaceae) is utilized as traditional medicine to cure a variety of diseases. It is well known for being a decorative tree, broad cultivated, very fragrant, and having a wide range of secon...

This study aimed to investigate the chemical composition of Coccoloba uvifera leaves and evaluate the antioxidant and antitumor effects of the total extract and its major metabolites. Four assays were used to determine the antioxidant activity, including radical scavenging abilities of 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2'-azinobis-3-ethylbenz...

Phytochemicals have played a significant role in the discovery of many clinically anticancer medicines. Thevetia peruviana being famous as an ornamental plant, widely cultivated, and including a wide variety of secondary metabolites this motivated us to explore more about its potential medical applications. In this study, the total methanol extract...

Abstract: Phytochemical investigation of 70% aqueous methanol extract of leaves of lemon balm (Melissa officinalisL., Lamiaceae) was subjected to different chromatographic separation techniques. The structures of isolated compounds were determined based on spectral data (UV, 1H-NMR, 13CNMR, and mass spectrometry). Also, assessment of the antioxidan...

Thevetia peruviana and Plumeria rubra (family Apocyanaceae) are shrubs cultivated in Egypt forornamental purposes. This study was done to compare the volatile oils of T. peruviana and P. rubra whichwere prepared by using the hydrodistillation method from fresh flowers and leaves of each plant. Identificationand quantification of the oil components...
