Phytochemical evaluation and anti-hemorrhoidal activity of bark of Acacia ferruginea DC.

ABSTRACT: The present study has been carried out to evaluate antihemorrhoidal activity of bark of Acacia ferruginea DC. The total phenolic, total flavonoid and saponins were determined. Anti-hemorrhoidal potential of bark extract was determined by levels of inflammatory cytokines such as TNF-?, IL-6, PGE2 and recto-anal coefficient (RAC). The histopathological examination was done to evaluate the severity score in the treated and untreated groups. The results of phytochemical screening of the hydroalcoholic extract of A. ferruginea revealed the presence of alkaloids, flavonoids, triterpenoid, saponins, tannins and phenolic compounds The total phenolic, flavonoid and saponin contents were found to be 438.8mg/g GAE, 66.6mg/gRE and 34%w/w respectively. Hydroalcoholic extract of bark of A. ferruginea significantly reduced the inflammatory cytokines {TNF-?(8.40±0.188), IL-6(3.95±0.181), PGE2(53.27±2.956) and RAC(0.998±0.094)}as compared to positive control group{TNF-?(13.36±0.141), IL-6(7.25±0.161), PGE2(82.34±3.395) and RAC(1.131 ± 0.008)}. Noticeably the results were comparable to that of standard pilex granules {TNF-? (7.12±0.166), IL-6(3.01±0.156), PGE2(42.51±2.157) and RAC (0.968±0.084)}. Molecular docking and structure based pharmacophore mapping further confirmed the anti-inflammatory mediated antihemorrhoidal activity of the hydroalcoholic extract. The antihemorrhoidal activity of hydroalcoholic extract of A. ferruginea may attribute to the flavonoids.

The present study has been carried out to evaluate antihemorrhoidal activity of bark of Acacia ferruginea DC. The total phenolic, total flavonoid and saponins were determined. Anti-hemorrhoidal potential of bark extract was determined by levels of inflammatory cytokines such as TNF-α, IL-6, PGE2 and recto-anal coefficient (RAC). The histopathological examination was done to evaluate the severity score in the treated and untreated groups. The results of phytochemical screening of the hydroalcohol ...[more]

Project description:The stem bark (SB) of Piptadeniastrum africanum (PA) has been extensively used in African traditional medicinal systems. However, there is a dearth of scientific information regarding its possible activity in the management of type II diabetes, Alzheimer's disease, and skin hyperpigmentation disorders. This study therefore attempted to elucidate the in vitro inhibitory action of ethyl acetate, methanol, and water extracts of P. africanum stem bark (PA-SB) on α-amylase, α-glucosidase, acetylcholinesterase, butyrylcholinesterase, and tyrosinase. Cell viability, catecholamine, and 3-hydroxykynurenine levels of hypothalamic HypoE22 cells exposed to PA-SB extracts were also investigated. The phytochemical profiles of the extracts were determined by high performance liquid chromatography (HPLC) and antioxidant properties were investigated. Saponin (867.42 mg quillaja equivalent/g) and tannin (33.81 mg catechin equivalent/g) contents were higher in the methanol extract. Multiple dihydroxy-trimethoxy(iso)flavone isomers, loliolide, eriodictyol, naringenin, luteolin, chrysoeriol, apigenin, and liquiritigenin, were characterized from PA-SB extracts using HPLC. The methanol extract of PA-SB showed highest inhibitory activity against acetylcholinesterase (4.88 mg galantamine equivalent (GALAE)/g extract), butyrylcholinesterase (5.37 mg GALAE/g extract), and tyrosinase (154.86 mg kojic acid equivalent/g extract) while α-glucosidase was effectively inhibited by the ethyl acetate extract (15.22 mmol acarbose equivalent/g extract). The methanol extract of PA-SB also showed potent antioxidant properties (493.87, 818.12, 953.07, and 732.19 mg Trolox equivalent/g extract, for 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid (ABTS), cupric reducing antioxidant capacity (CUPRAC), and ferric reducing antioxidant power (FRAP) assays, respectively). PA-SB extracts exhibited antioxidant activity and promising inhibition against key enzymes related to type II diabetes, Alzheimer's disease, and skin hyperpigmentation disorders. Additionally, all extracts were able to contrast hydrogen peroxide-induced oxidative stress, in HypoE22 cells, thus restoring basal catecholamine and 3-hydroxykinurenine levels, whereas only methanol and water extracts stimulated basal dopamine release. Overall, data from the present study contribute to the biological assessment of P. africanum that appears to be a promising source of natural compounds with protective and neuromodulatory effects.

Project description:BackgroundAlbizia coriaria Welw ex. Oliver (Fabaceae) is one of the plants used by herbalists in the East Africa community to prepare herbal remedies for the management of symptoms of TB. Despite its widespread use, the antimycobacterial activity of this plant was uninvestigated and there was contradicting information regarding its cytotoxicity.MethodsCytotoxicity (MTT), antimycobacterial activity (MABA), and phytochemical screening were conducted on crude extracts (hexane, chloroform, acetone, and methanol) of the stem bark of A. coriaria. Gas chromatography-mass spectrometry (GC-MS) followed by Fourier transform infrared (FTIR) spectroscopy was carried out on the acetone and methanol extracts. The binding affinities and descriptors of pharmacokinetics and toxicity of the identified compounds were predicted using computational modelling software.ResultsThe cytotoxic concentrations of all extracts were greater than 1000 μg/mL. The minimum inhibitory concentration of both the acetone and methanol extracts was 1250.0 ± 0.0 μg/mL against M. smegmatis, whereas that against M. tuberculosis was 937.0 ± 442.0 μg/mL and 2500.0 ± 0.0 μg/mL, respectively. Hexane and chloroform extracts were not active against both strains. Alkaloids, triterpenes, flavonoids, tannins, and saponins were the predominant phytochemicals present. GC-MS analysis revealed twenty-eight and nineteen compounds in acetone and methanol extracts, respectively. Among these was hydroquinone, which was previously reported to possess antimycobacterial activity. Seven compounds identified through GC-MS analysis had better binding affinities for the mycobacterial ATPase and polyketide synthase-13 than isoniazid and rifampicin. These compounds also showed variable but promising pharmacokinetic properties with minimum toxicity.ConclusionThere are phytochemicals in A. coriaria stem bark with potential antimycobacterial activity and acceptable cytotoxicity, which can be further explored and optimized for the development of novel antitubercular drugs.
