Abstract:

Grapefruit peels, often discarded as waste, have gained attention for their potential as a source of natural antioxidants, addressing the growing demand for sustainable and cost-effective alternatives to synthetic compounds. Oxidative stress-related disorders continue to pose significant health challenges, emphasizing the need for natural antioxidant sources. This study investigates the antioxidant properties of grapefruit peel phytochemicals using the blending extraction method. Fresh grapefruits were purchased from Minna main market, Niger State Nigeria and stored under controlled conditions

Abstract:

Ecoenzyme is a fermented solution from a mixture of fruit skin waste, vegetables, water and sugar. The fermentation process of various types of natural ingredients is known to be able to increase the content of various phytochemical compounds and antioxidants in these products. Phytochemicals are secondary metabolites that act as antioxidants. Antioxidants are compounds that can overcome oxidative damage due to reactive oxygen compounds that play a role in capturing free radicals. The purpose of this study was to determine the phytochemical and antioxidant content of each ecoenzyme. This type

Abstract:

The oxidant reactions of free radicals and molecules with unpaired electrons are thought to contribute to many health problems. Antioxidants restrict the deleterious effects of oxidative stress. These effects can be direct (i.e., eliminating certain free radicals) or indirect (i.e., preventing radical formation). The body produces certain endogenous antioxidants (i.e., enzymes), which can be consumed in the diet. Some dietary antioxidants such as vitamin E are essential nutrients (the body cannot function normally without them). The diet also contains other components that are capable of antio

Abstract:

Oxidative stress and its relation to the onset of several chronic diseases have been increasingly highlighted in recent years. In parallel, there has been an increasing interest in the antioxidant properties of phytochemicals. Phytochemicals are products of plant secondary metabolism, including structural polysaccharides, unsaturated fatty acids, pigments (chlorophylls, carotenoids, and anthocyanins), or phenolic compounds. Phytochemicals can be obtained from lower and higher plants, their fruits, and even from macro- or microalgae. Their diverse structural features are linked to different ben

Benign prostatic hyperplasia (BPH) is a common age-related urological disorder characterized by non-malignant enlargement of the prostate gland, often leading to lower urinary tract symptoms and reduced quality of life in aging men. Mounting evidence implicates oxidative stress and chronic inflammation as pivotal mechanisms in BPH pathogenesis, with increased reactive oxygen species (ROS) generation disrupting cellular homeostasis, promoting stromal proliferation, and impairing apoptosis. In recent years, phytochemical antioxidants have garnered significant attention as promising adjuncts or a
