The uses of toxicologically unscreened plants to enhance fertility can be associated with adverse consequences. This study aimed to evaluate the effect of the ethanolic stem back extract of (EEXA) on the fertility indices of male albino rats. Sixty male albino rats (weighing 200-250 gr) were grouped and administered by gavage with 200-800 mg/kg of EEXA daily for 15, 30, and 60 days. After the administration of EEXA, the rats were weighed and sacrificed. Blood samples were collected, serum samples were extracted, and evaluated for testosterone, follicle stimulating hormone, prolactin, estradiol, luteinizing hormone and progesterone levels. The testes, epididymis, and prostrate were harvested, weighed and testes were evaluated for sperm parameters. Significant increase in body weight (p = 0.02) with significant decreases in testes (p = 0.01), epididymis (p = 0.01), and prostate (p = 0.02) weights occurred in rats administered with EEXA when compared to the control group. Significant (p 0.001) dose and time- dependent decreases in sperm count, volume, motility, and normal morphology were obtained in rats administered with EEXA when compared to the control group. However, there were no significant (p > 0.05) effects on sperm pH when compared to control. Furthermore, luteinizing hormone, follicle stimulating hormone, and testosterone levels were significantly decreased whereas serum prolactin, estradiol, and progesterone levels were significantly increased in a dose-dependent fashion in rats administered with EEXA when compared to the control group. The findings in this study showed that the use of may be detrimental to male reproduction function.

Background Bioactivities of plant-based compounds had been shown to be influenced by properties of the extracting solvents. This study investigated the influence of ethanolic extract of Xylopia aethiopica (Dunal) A. Rich on the haematological and biochemical parameters in apparently healthy Wistar Rats using solvent partitioning. Methods The procedures involved partitioning of ethanolic extract of X. aethiopica (Dunal) A. Rich into n-hexane and aqueous fractions, chosen based on their differences in polarities and dielectric constants. The samples were administered at doses of 100 mg/kg body weight and 200 mg/kg body weight orally once per day for a period of fourteen (14) days to apparently healthy male Wistar rats that had been randomly selected into seven (7) groups. Haematological parameters and plasma biochemical indices were determined using standard protocols after the rats were sacrificed on the 15th day. Results The results showed that the levels of haematocrit and related parameters in all the groups that received the extract when compared to the control increased significantly ( p  < 0.05). Additionally, no detrimental effect was observed on the levels of endogenous antioxidants, liver and kidney function indices in the rats compared to the control. Conclusion In summary, on the basis of these findings, this study suggests that the extracts may be capable to alleviate the pathologies that are associated with haematological disorders through improvement of endogenous antioxidant status. The study proposes further evaluation on the molecular mechanism of bioactive components of X. aethiopica (Dunal) A. Rich as agents that can prevents anaemia.

In this study, the potential cytotoxicity of four plant extracts originated from Cameroon: Xylopia aethiopica (XA), Imperata cylindrica (IC), Echinops giganteus (EG) and Dorstenia psilurus (DP) were examined in vitro. We tested the anti-proliferative activity of the methanolic extracts of these compounds using MTT assay on seven different human cancer cell lines: HeLa, MDA-MB-231, A549, HepG2, U-87, SK-OV-3 and HL60. Induction of cell death was assessed by cell cycle analysis, apoptosis was determined by Annexin V-FITC binding and caspase 3/7 activity. As well, changes in mitochondrial membrane potential (MMP) and cell migration were tested. The genetic toxicity, using the alkaline comet assay, was evaluated. The studied extracts inhibited the cell proliferation of all tested cancer cell lines with concentration dependent effect over time. All of these extracts mainly induced apoptosis of HeLa cells by the accumulation of hypodiploid cells in the sub-G0/G1 phase and increasing the activity of caspase 3/7, as well they showed potential MMP disturbance and expressed a marked inhibitory effect on cell migration. Assessment of probable genetic toxicity by these extracts revealed no or minimum incidence of genetic toxicity. Therefore, the studied plant extracts are exhibiting potent anticancer activity based upon marked induction of tumor-cell death.

Parkinson disease is a neurogenerative disease common in adults and results in different kinds of memory dysfuntions. This study evaluated the monoamine oxidase B (MAO-B) inhibitory potential of kaurane diterpenoids previously isolated from Xylopia aethiopica through comprehensive computational approaches. Molecular docking study and molecular dynamics simulation were used to access the binding mode and interaction of xylopic acid and MAO-B enzyme. The ADMET properties of the phytochemical were evaluated to provide information on its druggability. The molecular docking and molecular dynamics simulation revealed xylopic acid as potential MAO-B inhibitor due to the good binding energy elicited and stability throughout the 100 ns simulation period. The ADMET properties of the ligand showed it as a promising drug candidate. The study recommend further comprehensive in vitro investigation towards the development of xylopic acid as potent MAO-B inhibitor.

This study investigated the potential of Xylopia aethiopica (Komba) to enhance the nutritional and functional properties of mish, a traditional Sudanese fermented dairy product. Motivated by the documented nutritional significance of both Xylopia aethiopica and mish, we examined dose-response effects of Komba fruit powder (incorporated at 0.0%, 0.5%, 1.0%, and 1.5% w/w) in mish produced from Dal Dairy Factory yoghurt. Chemical composition (AOAC methods), bioactive properties (DPPH radical scavenging assay), and sensory attributes (9-point structured hedonic scale; 60 panelists) were analyzed. Results demonstrated concentration-dependent improvements: The 1.5% Komba formulation exhibited significantly higher (P < 0.001) values than the control for total solids (17.0% vs. 13.80%), protein (5.95% vs. 4.75%), fat (5.05% vs. 3.94%), ash (2.77% vs. 1.25%), fiber (1.26% vs. 0.00%), and titratable acidity (2.06% vs. 1.70% lactic acid equivalent), alongside reduced pH (5.05 vs. 5.80). Mineral analysis confirmed elevated concentrations (P < 0.001) in the 1.5% sample: calcium (980.22 mg/100g vs. 895.60), potassium (482.61 mg/100g vs. 455.35), magnesium (182.33 mg/100g vs. 115.37), and iron (0.26 mg/100g vs. 0.19). Antioxidant activity increased proportionally to Komba concentration, with the 1.5% sample showing maximal DPPH radical scavenging (84.4% ± 0.001 vs. control: 67.1% ± 0.001), total flavonoids (76.7 ± 0.1 mg QE/100g DW vs. 30.5 ± 0.3), and total phenolics (39.9 ± 0.1 mg GAE/100g DW vs. 14.01 ± 0.1). These findings establish Xylopia aethiopica as a functional enhancer for mish, improving nutritional density and antioxidant capacity, supporting its application in value-added fermented foods and nutraceuticals.

This study computationally screened three key compounds (vanillin (VAN), oxophoebine (OPB), and dihydrochalcone (DHC)) derived from Xylopia aethiopica (Guinea pepper), a medicinal plant with known antiviral activity, against key druggable measles virus (MV) proteins (fusion protein (FUP), haemagglutinin protein (HMG), and phosphoprotein (PSP)). Each molecular species was subjected to a 100 ns molecular dynamics (MD) simulation following docking, and a range of postdynamic parameters including free binding energy and pharmacokinetic properties were determined. The docking scores of the resulting OPB-FUP (−5.4 kcal/mol), OPB-HMG (−8.1 kcal/mol), and OPB-PSP (−8.0 kcal/mol) complexes were consistent with their respective binding energy values (−25.37, −28.74, and −40.68 kcal/mol), and higher than that of the reference standard, ribavirin (RBV) in each case. Furthermore, all the investigated compounds were thermodynamically compact and stable, especially HMG of MV, and this observation could be attributed to the resulting intermolecular interactions in each system. Overall, OPB may possess inhibitory properties against MV glycoproteins (FUP and HMG) and PSP that play important roles in the replication of MV and measles pathogenesis. While OPB could serve as a scaffold for the development of novel MV fusion and entry inhibitors, further in vitro and in vivo evaluation is highly recommended.

Aside from its multiple medicinal uses, the fruit of Xylopia aethiopica is widely used in Africa as food. Herein, we characterize the protein profiles, mineral content and bioactive phytochemical composition of the seeds of this plant sourced in Ghana and Nigeria. Using label-free proteomics, a total of 677 proteins were identified, with 260 found in the Ghana-sourced samples while 608 proteins were detected in the samples from Nigeria. However, 114 proteins were common between the samples from the two countries, among which 48 were significantly changed. Bioinformatics and functional analyses revealed that the differential levels of the proteins were mainly linked to pathways involved amino acids metabolism and biosynthesis. The significantly changed proteins related mainly to catalytic activity and carbon metabolism. The samples from Nigeria also exhibited superior qualities in terms of their antioxidant effects, and total phenolic and flavonoid content. Finally, only the content of Na varied to a statistically significant level. This study lends support to its culinary use and hints towards the impact of location of cultivation on the quality of the seeds. There is however need for further mechanistic investigations to unravel the underlying reasons for the observed differences.

The herbicide “Roundup” is used extensively in agriculture to control weeds. However, by translocation, it can be deposited in plants, their proceeds, and the soil, thus provoking organ toxicities in exposed individuals. Neurotoxicity among others is one of the side effects of roundup which has led to an increasing global concern about the contamination of food by herbicides. Xylopia aethiopica is known to have medicinal properties due to its antioxidative and anti-inflammatory properties, and it is hypothesized to neutralize roundup-induced neurotoxicity. Thirty-six (36) Wistar rats were used for this study. The animals were shared equally into six groups with six rats each. Glyphosate administration to three of the six groups was done orally and for 1 week. Either Xylopia aethiopica or vitamin C was co-administered to two of the three groups and also administered to two other groups and the final group served as the control. Our studies demonstrated that glyphosate administration led to a significant decrease in antioxidants such as catalase, superoxide dismutase, glutathione, and glutathione peroxidase. We also observed a significant increase in inflammatory markers such as tumor necrosis factor-α, interleukin 6, C-reactive protein, and immunohistochemical expression of caspase-3, cox-2, and p53 proteins ( p < 0.05). However, Xylopia aethiopica co-administration with glyphosate was able to ameliorate the aforementioned changes when compared to the control ( p < 0.05). Degenerative changes were also observed in the cerebellum, hippocampus, and cerebral cortex upon glyphosate administration. These changes were not observed in the groups treated with Xylopia aethiopica and vitamin C. Taken together, Xylopia aethiopica could possess anti-oxidative and anti-inflammatory properties that could be used in combating glyphosate neurotoxicity. Graphical Abstract

Background/Objectives: Taeniasis, a zoonotic infection, is a common foodborne disease. Niclosamide and praziquantel have proven to be effective in treating it, but the use of the same drugs can lead to resistance, so alternative drugs need to be explored. This study investigated the anthelmintic potential of derived fractions from hydroethanolic extracts (HEs) of Aframomum melegueta (AM) and Xylopia aethiopica (XA), two medicinal plants known for their diverse bioactive properties. Methods: AM-HE fractions (dichloromethane fraction (DCMF), ether fraction (EF), aqueous fraction (AF)) and XA-HE fractions (chloroform fraction (CF), ether fraction (EF), and aqueous fraction (AF)) were used, and in vitro anthelmintic activity was assessed against Taenia spp. by using an adult motility assay for the worm’s paralysis time determination. The parasiticidal and parasitostatic activity was also tested on Taenia spp. adult worms. Cell viability was further evaluated using propidium iodide (PI) staining, with albendazole (20 mg/mL) as the reference drug. Results: The three fractions of each plant exhibited significant, dose-dependent anthelmintic activity, with AM-HE and XA-CF showing the greatest effects at 20 mg/mL. AM-EF demonstrated significant activity at 0.4% and 0.8%. Irreversibility tests revealed that most of the treated worms remained paralysis, except those exposed to the AF of both plants. PI staining confirmed the dose-dependent mortality of Taenia cells treated with HE, DCMF, and AF of AM. Conclusions: These results underscore the potential of AM and XA extracts and fractions as alternative treatments for helminth infections. Further, in vivo studies are warranted to confirm their safety and therapeutic efficacy.

In Cameroon, local plants are traditionally used as remedies for a variety of ailments. In this regard, several papers report health benefits of Cameroonian spices, which include antioxidant and anti-microbial properties, whereas gastric anti-inflammatory activities have never been previously considered. The present study investigates the antioxidant and anti-inflammatory activities of hydro-alcoholic extracts of eleven Cameroonian spices in gastric epithelial cells (AGS and GES-1 cells). The extracts showed antioxidant properties in a cell-free system and reduced H2O2-induced ROS generation in gastric epithelial cells. After preliminary screening on TNFα-induced NF-κB driven transcription, six extracts from Xylopia parviflora, Xylopia aethiopica, Tetrapleura tetraptera, Dichrostachys glomerata, Aframomum melegueta, and Aframomum citratum were selected for further studies focusing on the anti-inflammatory activity. The extracts reduced the expression of some NF-κB-dependent pro-inflammatory mediators strictly involved in the gastric inflammatory process, such as IL-8, IL-6, and enzymes such as PTGS2 (COX-2), without affecting PTGS1 (COX-1). In conclusion, the selected extracts decreased pro-inflammatory markers by inhibiting the NF-κB signaling in gastric cells, justifying, in part, the traditional use of these spices. Other molecular mechanisms cannot be excluded, and further studies are needed to better clarify their biological activities at the gastric level.
