“…These and other reported activities of phytochemicals work together in support of the various ethnopharmacological application of the specie. The current observations were similar to those reported for aqueous whole fruit extract [31,32], aqueous and ethanolic extract of the stem bark [33] and ethanolic extract of leaves [17]. The observed differences in the qualitative and quantitative levels of these phytochemicals could be attributed to geographical differences in plant samples used.…”

Introduction: The role of medicinal plants in meeting the healthcare needs of the populace, particularly in developing countries cannot be overemphasized. They provide holistic treatment and wellbeing due to a plethora of phytochemicals found in them. Among such is Tetrapleura tetraptera (Schum. & Thonn.) Taub., a multipurpose tree plant with varied biological activities. The current study was aimed at assessing the basic phytochemical constituents, free radical scavenging activity as well as the antimicrobial effect on various solvent extracts of leaves, fruit and stem bark of T. tetraptera of Ghanaian origin. Materials and Methods: Aqueous, 50% hydroethanolic and methanolic extracts were made from the leaves, fruits, and stem bark of T. tetraptera. They were assessed for the qualitative and quantitative phytochemical constituents, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity, antimicrobial activity as well as the spectroscopic properties (Ultraviolet – visible and Fourier-transform infrared spectroscopy). Compounds in the methanolic extracts were evaluated using the gas chromatography–mass spectrometry. Results: Tannins, reducing sugars, coumarins and flavonoids were present in all extracts while hydroethanolic and methanolic extracts were rich in phenols, tannins and flavonoids, especially for the stem bark. Leaf extracts had better antimicrobial activity against Pseudomonas aeruginosa, Staphylococcus aureus, Escherichia coli, Candida albicans and Proteus mirabilis. Conclusion: Generally, leaves and stem bark extracts of T. tetraptera are rich in biologically active phytochemicals, supporting their use in ethnomedicine and could be exploited further for other biological activities.

Nanotechnology is making exceptional progress in the medical eld. The development of new systems for the delivery of plant ingredients brings bene ts such as good bioavailability, solubility, sustained release, and enhanced potential. To the best of our knowledge, there is no report on nanocomposites from Tetrapleura tetraptera despite its wide range of ethnopharmacological uses including management of the in ammatory diseases. This study aimed to prepare chitosan and cellulose-based nanocomposite with anti-in ammatory potential. The biocomposite showed an encapsulation e ciency of 69.4%. Their formation was con rmed by a peak at 290 nm in UV-Vis. Infrared spectrophotometry proves the formation of a mixed polysaccharide and polyphenols system. No signs of toxicity and no deaths were found, therefore the lethal dose 50 (LD 50 ) is higher than 2000 mg/kg. The biocomposite has an antiin ammatory activity in vitro with a maximum inhibition of 99.5% and an anti-in ammatory activity in vivo with a maximum inhibition of 98.7% for a dose of 200 mg/kg. The synthesized biocomposite from the aqueous extract of the fruits of Tetrapleura tetraptera showed an anti-in ammatory property with satisfactory safety.
