Topic: Ethnobotany

Description: My research interests is Ethnobotany. I am dedicated to collaborating with local communities to respectfully gather and document their ethnomedicinal practices, traditional plant uses, and ecological knowledge. I am also interested in investigating the potential of traditional plant-based remedies in the development of new pharmaceuticals and therapeutics. By working closely with indigenous healers and scientists, I seek to identify medicinal plants with significant therapeutic properties and investigate their chemical constituents, modes of action, and potential applications in modern medicine. This research can lead to the discovery of new bioactive compounds and contribute to the development of alternative and sustainable healthcare solutions.

Effects of Extraction Solvents on the Yields, Phytochemical Constituents and Antioxidant Activities of Bryophyllum pinnatum and Cocos nucifera.

IntroductionThe traditional African medical system relies heavily on medicinal plants, the oldest and most diverse form of treatment.Bryophyllum pinnatum commonly called miracle leaf belongs to the family Crassulaceae and is one of the effective medicinal plants used in the treatment of diuresis, diabetes, kidney stones, respiratory tract infections, boils, wounds and insect bites.Cocos nucifera of the family Arecaceae is also known as coconut. It is used in traditional medicine to relieve muscular pains, treat urinary tract infections, arthritis and skin infections.Examining the effects of various solvents on the extraction yields, phytochemical constituents and antioxidant activities of the leaf extracts of B. pinnatum and C. nucifera was the aim of this study.Methodology.Phytochemical screenings of the acetone and ethanol leaf extracts of B. pinnatum and C. nucifera were carried out using the laboratory procedures of Trease and Evans 2002 and Gas Chromatography Mass Spectrometry analysis.The antioxidant activities of the extracts were evaluated using ABTS, DPPH, nitric oxide and super oxide radical scavenging assays.Results.It was observed that the extraction yields, phytochemical constituents and antioxidant activities were significantly influenced by the solvents utilized. For both plants extracts, ethanol was shown to be the most efficient extraction solvent, producing the higher extraction yields. However, acetone plants extracts contained the highest concentration of phenolics, tannins, flavonoids, terpenoids and steroids. When compared with ethanol extract, acetone extracts of the two plants showed exceptional antioxidant activities.Contribution to Knowledge.This study showed that extraction solvents can interfere with the yields and biological activities of the plant extracts.
