Comparative Analysis of the Antibacterial, Antioxidant, Phytochemical, and Hair-Growth-Promoting Properties of Three Medicinally Important Plants, Calotropis procera (Aiton) Dryand, Moringa oleifera Lam., and Avicennia marina (Forssk.) Vierh. on Alopecia Disease

This research represents a thorough examination of the antibacterial, antioxidant, phytochemical, and hair-growth-promoting qualities of three prominent medicinal plants: Calotropis procera (Aiton) W.T. Aiton, Moringa oleifera Lam., and Avicennia marina (Forssk.) Vierh. Due to their easy accessibility in Karachi, these plants can be used and studied. Their extensive distribution raises the possibility that local populations have long used them for a variety of health advantages, including hair care. This research study intended to assess the bioactive compounds i.e., phenolic compounds present in these plants and their efficacy in various applications, ultimately arguing for their use as natural alternatives to synthetic agents. In recent years, there has been an increase in interest in the exploration of natural products for their potential therapeutic applications, especially in the pharmaceutical and cosmetics industries. The evaluation of this research was focused on physiochemical properties, such as specific gravity, pH, and appearance, which offer crucial information on the composition and stability of extracts made from these plants, was the main emphasis of the study’s first section. It was essential to comprehend these factors in order to create herbal products that are sustainable throughout time. The disc diffusion method was used to assess antibacterial efficacy against a variety of microorganisms, both Gram-positive and Gram-negative. Our findings showed that A. marina stood out with strong antibacterial activity, suggesting its potential as a treatment for bacterial illnesses, but M. oleifera and C. procera showed only moderate antibacterial effects. Additionally, antioxidant activity was evaluated using the content of phenolic compounds and the DPPH (2,2-diphenyl-1-picrylhydrazyl) assay. All samples showed concentration-dependent antioxidant activity, and stronger scavenging activity was correlated with higher phenolic content. Significantly, the highest phenolic concentration was discovered in A. marina extracts, indicating their ability to fight oxidative stress and associated illnesses. Using a rat model, the third section of the study sought to assess the selected plants’ capacity to stimulate hair growth. Hair regeneration was much improved by the formulations based on A. marina and C. procera, although M. oleifera had less of an impact. An irritancy test validated the herbal gels’ safety profile by confirming that the formulations were non-irritating and showing no signs of erythema in the animals. Furthermore, the three-month stability tests showed that the herbal gel compositions’ pH and appearance stayed constant, indicating their potential for long-term use and storage. Bioactive substances were identified by the phytochemical study, with phenolic molecules which are well known for their anti-oxidative qualities being especially prevalent, in addition, FTIR spectroscopy characterized chemical composition. Total phenolic content test supported the idea that increased concentrations lead to improved bioactivity by showing a distinct correlation between concentration and phenolic content. This research concludes by demonstrating the strong antibacterial, antioxidant, and hair-growth- promoting qualities of A. marina, M. oleifera, and C. procera extracts. This highlights the potential use of these extracts in the development of natural substitutes for synthetic compounds in the pharmaceutical and cosmetic industries. These data not only validate the traditional applications of these plants but also open the door for further investigation into their effects, both separately and in combination, which could result in the creation of innovative herbal compositions that capitalize on their medicinal properties. This study’s focus on natural goods supports the incorporation of plant-based solutions into routine health and beauty routines and is in line with a growing global trend towards sustainability and health-conscious consumer choices.
