Antiulcer Effect of Aqueous Ethanolic Extracts of Pseudocedrela kotschyi (Schweinf) Harms (Meliaceae) and Ximenia americana L. (Olacaceae). J Exp Pharmacol 2023; 15:231-240. [PMID: 37275787 PMCID: PMC10237205 DOI: 10.2147/jep.s393168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2022] [Accepted: 05/06/2023] [Indexed: 06/07/2023] Open
Abstract
Purpose This study aimed to provide pharmacological evidence of Pseudocedrela kotschyi and Ximenia americana in preventing or healing peptic ulcers claimed by traditional healers in Burkina Faso. Methods The trunk bark of Pseudocedrela kotschyi and the roots bark of Ximenia americana (Olacaceae) were macerated in mixed ethanol/water (80:20), respectively, to obtain dried extracts. Two models of hydrochloric acid (HCl, 0.3 M/ethanol, 60%) and hypothermic stress-induced peptic ulcer were used. The cytoprotective effect of individual or combined plant extracts was assessed at 1; 10; 30mg/kg. bw. Then, the healing effect of the extracts at 10mg/kg.bw was evaluated within 21 days of treatment on the hydrochloric acid-induced ulcer model. The extracts' antioxidant activity and phenolic content were assessed to support the plant extracts' efficiency. Results The extracts of P. kotschyi and X. americana at 10 mg/kg.bw reduced ulceration index in hydrochloric acid- and hypothermic stress-ulcer models by more than 83% and 65%, respectively. The extract from X. americana at 10mg/kg.bw allowed complete ulcer healing but not the association of the two plant extracts. The plant extracts had IC50of inhibition of DPPH radical lower than 5μg/mL and total ferric reducing antioxidant power of more than 77 mg EQAA/100mg. The total polyphenolic content was 64.82 ±0.99 and 53.75 ±1.39 mg EGA/g of dried extract of P. kotschyi and X. americana, respectively. Conclusion X. americana extract is better than the combined two plant extracts in gastric cytoprotection and ulcer healing. Further investigations are needed to highlight mechanism-based effects.

LC-MS Based Analysis and Biological Properties of Pseudocedrela kotschyi (Schweinf.) Harms Extracts: A Valuable Source of Antioxidant, Antifungal, and Antibacterial Compounds. Antioxidants (Basel) 2021; 10:antiox10101570. [PMID: 34679706 PMCID: PMC8533236 DOI: 10.3390/antiox10101570] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/11/2021] [Revised: 09/29/2021] [Accepted: 09/30/2021] [Indexed: 12/14/2022] Open
Abstract
The impact of two extraction solvents on the phenolic composition, antioxidant, and enzymes inhibitory and antimicrobial activities of two parts (leaves and stem bark) of P. kotschyi was studied. Two different LC-DAD-MSn approaches were used to identify and quantify the bioactive compounds in the different extracts. A total of thirty-two compounds were quantified, being the procyanidin the most abundant in stem bark while catechin and flavonoids are most abundant in leaves. Overall, the stem bark extraction using methanol showed higher amounts of total phenolic (131.83 ± 1.81 mg GAE/g) and flavanol (14.14 ± 0.11 mg CE/g) while the leaves extraction using water exhibited stronger levels of total flavonoid (44.95 ± 0.38 mg RE/g) and phenolic acid (63.58 ± 2.00 mg CAE/g). As regards the antioxidant assays, methanol stem bark extracts were characterized by the highest antioxidant activities (DPPH: 1.94 ± 0.01 mmol TE/g, ABTS: 3.31 ± 0.01 mmol TE/g, FRAP: 2.86 ± 0.02 mmol TE/g, CUPRAC: 5.09 ± 0.08 mmol TE/g, phosphomolybdenum: 5.16 ± 0.23 mmol TE/g and metal chelating: 17.12 ± 0.46 mg EDTAE/g). In addition, the methanolic extracts of stem bark had highest impact on acetylcholinesterase (2.54 mg GALAE/g), butyrylcholinesterase (5.48 mg GALAE/g). In contrast, the methanolic extracts of leaves was potent against tyrosinase (77.39 ± 0.21 mg KAE/g) and α-glucosidase (0.97 ± 0.01 mmol ACAE/g), while a higher anti-α–amylase (0.97 ± 0.01 mmol ACAE/g) was observed for water extracts of the same part. All of the tested extracts showed inhibitory effects on elastase, except methanolic leaves extracts. Additionally, the extracts exhibited appreciable antifungal toward A. ochraceus, A. fumigatus, P. ochrochloron, T. viride, and P. funiculosum and promising antibacterial activity against M. flavus, S. aureus, L. monocytogenes, E. coli, P. aeruginosa, E. cloacae, and S. typhimurium. Taken together, the outcomes demonstrated P. kotschyi as a novel source of bioactive molecules of interest with an evident therapeutic value.
