Abstract
The use of medicinal plants as food and medicine has been a common practice in the world, especially in tropical African countries. One such plant in West Africa is Uvaria chamae, also known as Bush banana, renowned for its diverse ethnomedicinal applications and, more recently, for its pharmacological activities attributed to a rich array of phytochemical constituents. Various parts of the plant have been traditionally employed for the treatment of diverse health issues such as digestive disorders, fever, dysmenorrhea, cancer, wound healing, and many more. To unravel the bioactive compounds responsible for these medicinal properties, a comprehensive phytochemical analysis has been undertaken. Notable isolates include chamanetin, dichamanetin, uvaretin, and uvarinol from different parts of the plant. The pharmacological evaluation of these compounds has revealed significant anticancer and antimicrobial properties. Therefore, this review provides a thorough examination of the phytochemicals derived from Uvaria chamae, detailing their associated pharmacological activities both in vitro and in vivo. The review emphasizes the potential of Uvaria chamae as a valuable source of lead compounds for cancer chemotherapy and antimicrobial drug discovery.

Obasi DC, Ogugua VN. GC-MS analysis, pH and antioxidant effect of Ruzu herbal bitters on alloxan-induced diabetic rats. Biochem Biophys Rep 2021; 27:101057. [PMID: 34179519 PMCID: PMC8214189 DOI: 10.1016/j.bbrep.2021.101057] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Revised: 06/07/2021] [Accepted: 06/10/2021] [Indexed: 12/19/2022] Open
Abstract
The study investigated the antioxidant effect of Ruzu herbal bitters (RHB) on alloxan-induced diabetic rats, the pH and the bioactive components of RHB using gas chromatography and mass spectroscopy (GC-MS). Fifty-four adult albino rats were divided into nine groups of six rats each. Group 1 was the normal control. Groups 2-6 were diabetic. Group 2 was untreated positive control, while groups 3-6 were respectively treated with 5 mg/kg b. w of glibenclamide, 0.14, 0.29 and 0.57 ml/kg b. w of RHB for 21 days. Groups 7-9 were not diabetic but treated as in groups 4-6 respectively. The results showed significant (p < 0.05) increase in the blood glucose level and significant (p < 0.05) decrease in weight in diabetic untreated group compared to the normal control. The oxidative stress parameters showed significant (p < 0.05) increases in the serum activities of superoxide dismutase (SOD) and catalase (CAT), with significant (p < 0.05) decrease in glutathione peroxidase (GPx); while there were significant (p < 0.05) increases in the levels of vitamin C (VIT C), vitamin E (VIT E), C-reactive protein (CRP) and malondialdehyde (MDA), with significant (p < 0.05) decrease in the level of glutathione (GSH) in the diabetic untreated group compared to the normal control group. However, treatment of the diabetic groups with different doses of RHB resulted in the reversal of the effects to near-normal levels in a dose-dependent manner. The pH of RHB was found to be 3.45. The GC-MS result of RHB revealed the presence of 10 bioactive compounds, out of which four are pharmacologically important antioxidants: 11-Octadecenioc acid -Methyl esther, 2,7-Dioxatricyclodeca-4, 9-diene, Cis-Z-α- Bisabolene epoxide, and Tetradecanoic acid (lauric acid). Thus, the study revealed that Ruzu herbal bitters possesses antidiabetic and antioxidant activities due to the bioactive antioxidant compounds it contains.

Olagunju AI, Oluwajuyitan TD, Oyeleye SI. Effect of Plantain Bulb's Extract-Beverage Blend on Blood Glucose Levels, Antioxidant Status, and Carbohydrate Hydrolysing Enzymes in Streptozotocin-Induced Diabetic Rats. Prev Nutr Food Sci 2020; 25:362-374. [PMID: 33505930 PMCID: PMC7813600 DOI: 10.3746/pnf.2020.25.4.362] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2020] [Accepted: 10/13/2020] [Indexed: 11/13/2022] Open
Abstract
The pharmacological properties of various parts of plantain trees have directed its use in folkloric management of diabetes and other human ailments. However, little is known about plantain bulb extract (PBE) and their mechanisms of action. This study evaluated the effect of PBE-beverage blends (including 1% and 2 % cocoa powder) sweetened with honey on blood glucose levels, antioxidant status, and carbohydrate hydrolysing enzyme activities in streptozotocin (STZ)-induced diabetic rats. Animals were selected at random and distributed into 7 groups (n=7), as follows: normal control (NC), untreated diabetic rats, diabetic rats treated with acarbose (STZ-ACA), diabetic rats administered PBE (STZ- PBE), diabetic rats administered honey and PBE (STZ-HPBE), diabetic rats administered 1% cocoa powder-with HPBE blend (STZ-CHPBE-1), and diabetic rats administered 2% cocoa powder with HPBE blend (STZ-CHPBE-2). Compared with the controls, untreated diabetic rats exhibited increased blood glucose levels and hydrolysing enzyme activities, and significant decreases in the activities of antioxidant (catalase, superoxide dismutase, glutathione-S-transferase, and glutathione peroxidase) enzyme and non-enzymatic (glutathione) antioxidants. However, changes in activities were comparatively reversed in all rats administered plantain bulb formulations. CHPBE-2 was slightly more effective than CHPBE-1. Overall, both blends could serve as nutraceutical and/or functional drinks in the management of diabetes.
