[PMID: 38319066 DOI: 10.1080/07391102.2024.2313167] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/17/2023] [Accepted: 01/25/2024] [Indexed: 02/07/2024]
Abstract
Streptomyces spp. are considered excellent reservoirs of natural bioactive compounds. The study evaluated the bioactive potential of secondary metabolites from Streptomyces sp. strain 130 through PKS-I and NRPS gene-clusters screening. GC-MS analysis was done for metabolic profiling of bioactive compounds from strain 130 in the next set of experiments. Identified antifungal compounds underwent ADMET analyses to screen their toxicity. All compounds' molecular docking was done with the structural gene products of the aflatoxin biosynthetic pathway of Aspergillus flavus. MD simulations were utilized to evaluate the stability of protein-ligand complexes under physiological conditions. Based on the in-silico studies, compound 2,4-di-tert butyl-phenol (DTBP) was selected for in-vitro studies against Aspergillus flavus. Simultaneously, bioactive compounds were extracted from strain 130 in two different solvents (ethyl-acetate and methanol) and used for similar assays. The MIC value of DTBP was found to be 314 µg/mL, whereas in ethyl-acetate extract and methanol-extract, it was 250 and 350 µg/mL, respectively. A mycelium growth assay was done to analyze the effect of compounds/extracts on the mycelium formation of Aspergillus flavus. In agar diffusion assay, zone of inhibitions in DTBP, ethyl-acetate extract, and methanol extract were observed with diameters of 11.3, 13.3, and 7.6 mm, respectively. In the growth curve assay, treated samples have delayed the growth of fungi, which signified that the compounds have a fungistatic nature. Spot assay has determined the fungal sensitivity to a sub-minimum inhibitory concentration of antifungal compounds. The study's results suggested that DTBP can be exploited for antifungal-drug development.Communicated by Ramaswamy H. Sarma.

Exploring the Bioactive Mycocompounds (Fungal Compounds) of Selected Medicinal Mushrooms and Their Potentials against HPV Infection and Associated Cancer in Humans. LIFE (BASEL, SWITZERLAND) 2023; 13:life13010244. [PMID: 36676192 PMCID: PMC9861011 DOI: 10.3390/life13010244] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 12/11/2022] [Accepted: 12/30/2022] [Indexed: 01/19/2023]
Abstract
Medicinal mushrooms have been used as a medicinal tool for many centuries and, nowadays, are used in the prevention and therapy of various diseases, including as an adjunct to cancer treatment. It is estimated that 14-16% of global cancer cases are caused by infectious events; one well-known infectious agent that leads to cancer is the human papillomavirus (HPV). HPV is responsible for more than 99.7% of cervical cancer cases and also may play a role in vaginal, vulvar, penile, anal, rectal, and oropharyngeal carcinogenesis. Coriolus versicolor, a basidiomycetes class mushroom, consists of glycoproteins called polysaccharide-K (PSK) and polysaccharopeptide (PSP), which are mainly responsible for its effectiveness in the fight against a variety of cancers. Its beneficial effect lies in its ability to arrest different phases of the cell cycle, immunomodulation or induction of apoptosis. Coriolus versicolor extractcan reduces BCL-2 expression or increases the expression of p53 tumour suppressor genes in breast tumour cell lines. Inhibition of proliferation was also demonstrated with HeLa cells, while cervical cytology abnormalities improved in patients who locally applied Coriolus versicolor-based vaginal gel. Coriolus versicolor extract itself, and also its combination with another medicinal mushroom, Ganoderma lucidum, leads to improved HPV clearance in HPV cervical or oral-positive patients. Medicinal mushrooms can also increase the effectiveness of vaccination. This review considers the use of medicinal mushrooms as a suitable adjunct to the treatment of many cancers or precanceroses, including those caused by the HPV virus.

Abstract
Objectives Mushrooms are fungi with nutritional and health benefits. Lentinus squarrosulus Mont., an edible fungus, has traditional usage and relevance in local therapy for managing metabolic diseases. In that view, this study aimed to evaluate the in vitro anti-obesity, anti-diabetic, and cytotoxic potential of the chloroform/methanol extract (CME) and aqueous extract (AE) of the mushroom. Materials and Methods L. squarrosulus was identified using molecular biology tools. The CME and AE were obtained sequentially and, then, subjected to α-amylase, α-glucosidase, and lipase inhibitory enzyme assays as well as total phenolic content (TPC) and flavonoid content (TFC) estimations. The cytotoxic potential of extract fractions of L. squarrosulus was assessed using the brine shrimp lethality assay. Results The molecular identification of the mushroom displayed that the internal transcribed spacer sequence was an equivalent match to that of L. squarrosulus with a high percentage similarity, and thus assigned a unique accession number (KT120043.1). The CME of L. squarrosulus had higher TPC, TFC, and α-glucosidase inhibitory activity than AE. Furthermore, AE of the mushroom showed a higher lipase inhibitory potential with an IC50 value of 22.28 ± 0.65 μg/mL than the CME, while that of the reference, i.e. orlistat was 2.28 ± 0.34 μg/mL. However, these extracts exhibited very low or no α-amylase inhibitory and cytotoxic activity at the tested concentrations. Conclusion This study reveals that CME of L. squarrosulus, rich in polyphenols and flavonoids, possesses considerable α-glucosidase and lipase inhibitory activities.

Protective and Curative Activities of Paenibacillus polymyxa against Zucchini yellow mosaic virus Infestation in Squash Plants. BIOLOGY 2022; 11:biology11081150. [PMID: 36009777 PMCID: PMC9405448 DOI: 10.3390/biology11081150] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/28/2022] [Revised: 07/26/2022] [Accepted: 07/28/2022] [Indexed: 11/16/2022]
Abstract
The use of microbial products as natural biocontrol agents to increase a plant's systemic resistance to viral infections is a promising way to make agriculture more sustainable and less harmful to the environment. The rhizobacterium Paenibacillus polymyxa has been shown to have strong biocontrol action against plant diseases, but its antiviral activity has been little investigated. Here, the efficiency of the culture filtrate of the P. polymyxa strain SZYM (Acc# ON149452) to protect squash (Cucurbita pepo L.) plants against a Zucchini yellow mosaic virus (ZYMV, Acc# ON159933) infection was evaluated. Under greenhouse conditions, the foliar application of the culture filtrate of SZYM either in protective or curative treatment conditions enhanced squash growth, reduced disease severity, and decreased ZYMV accumulation levels in the treated plants when compared to the non-treated plants. The protective treatment group exhibited the highest inhibitory effect (80%), with significant increases in their total soluble carbohydrates, total soluble protein content, ascorbic acid content, and free radical scavenging activity. Furthermore, a considerable increase in the activities of reactive oxygen species scavenging enzymes (superoxide dismutase, polyphenol oxidase, and peroxidase) were also found. In addition, the induction of systemic resistance with a significant elevation in the transcriptional levels of polyphenolic pathway genes (CHS, PAL, and C3H) and pathogenesis-related genes (PR-1 and PR-3) was observed. Out of the 14 detected compounds in the GC-MS analysis, propanoic acid, benzenedicarboxylic acid, tetradecanoic acid, and their derivatives, as well as pyrrolo [1,2-a] pyrazine-1,4-dione, hexahydro-3-(2-methylpropyl) were the primary ingredient compounds in the ethyl acetate extract of the SZYM-culture filtrate. Such compounds may act as elicitor molecules that induce systemic resistance against viral infection. Consequently, P. polymyxa can be considered a powerful plant growth-promoting bacterium (PGPB) in agricultural applications as well as a source of bioactive compounds for sustainable disease management. As far as we know, this is the first time that P. polymyxa has been shown to fight viruses in plants.

Abstract
The use of complementary herbal medicines has recently increased in an attempt to find effective alternative therapies that reduce the adverse effects of chemical drugs. Portulacaria afra is a rich source of phytochemicals with high antioxidant activity, and thus may possess health benefits. This study used the latest developments in GC-MS coupling with molecular docking techniques to identify and quantify the phytoconstituents in P. afra tissue extracts. The results revealed that n-butanol P. afra (BUT-PA) dry extracts contained total phenolic and flavonoids contents of 21.69 ± 0.28 mgGAE/g and 196.58 ± 6.29 mgGAE/g, respectively. The significant potential of antioxidants was observed through CUPRIC, FRAP, and ABTS methods while the DPPH method showed a moderate antioxidants potential for P. afra. Enzymatic antioxidants, superoxide dismutase, peroxidase and catalase also showed a better response in the BUT-PA dry extracts. The thrombolytic activity of the BUT-PA extracts ranged from 0.4 ± 0.32 to 11.2 ± 0.05%. Similarly, hemolytic activity ranged from 5.76 ± 0.15 to 9.26 ± 0.15% using the standard (triton x) method. The BUTPA and CHPA showed moderate acetylcholinesterase and butrylcholinesterase inhibition, ranging from 40.78 ± 0.52 to 58.97 ± 0.33, compared to galantamine. The carrageenan induced hind-paw edema assay, while BUT-PA extracts showed anti-inflammatory properties in a dose-dependent manner. Furthermore, 20 compounds were identified in the BUTPA extracts by GC-MS. Molecular docking was performed to explore the synergistic effect of the GC-MS-identified compounds on COX-1 and COX-2 inhibition. A high binding affinity was observed for Stigmastan-3, 5-diene, Phthalic acid, 3. Alpha-Hydroxy-5, 16-androstenol. The computed binding energies of the compounds revealed that all the compounds have a synergistic effect, preventing inflammation. It was concluded that active phytochemicals were present in P. afra, with the potential for multiple pharmacological applications as a latent source of pharmaceutically important compounds. This should be further explored to isolate secondary metabolites that can be employed in the treatment of different diseases.

JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2022; 102:2120-2126. [PMID: 34599826 DOI: 10.1002/jsfa.11553] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/16/2021] [Revised: 09/24/2021] [Accepted: 10/02/2021] [Indexed: 06/13/2023]
Abstract
BACKGROUND Higher fungi such as oyster mushrooms have been well reported to have vast therapeutic and nutritive importance due to their bioactive constituents. Today, many interesting facts are also emerging regarding their importance in pest control. In this study, Pleurotus floridanus, P. ostreatus and P. sajor-caju were studied for exopolysacharide (EPS) and antioxidant production under different carbon sources, and assayed for larvicidal properties. RESULTS We observed a positive response of these mushrooms to carbon sources. The highest EPS was produced by P. sajor-caju under sucrose carbon source, whereas P. ostreatus and P. floridanus preferred glucose. The antioxidant activity of their EPS was confirmed using radical scavenging of 1,1-diphenyl-2-picrylhydrazyl and potassium ferricyanide reduction methods. We also established the inhibition of lipid peroxidation by the EPS produced by these mushrooms, although this was concentration dependent, while P. floridanus EPS had the highest antioxidant properties. An EPS concentration of 100 mg L-1 from all the mushrooms was sufficient for inhibition of lipid peroxidation; this also showed a significant difference from the scavenging effect of butylated hydroxytoluene. All the mushroom extracts in this study had positive inhibitory effects on the late third and early fourth stages of Anopheles gambiae. However, they were significantly different from each other as P. floridanus recorded a lethal concentration (LC50 ) of 0.0.563, P. ostreatus had an LC50 of 0.352, while P. sajor-caju had an LC50 of 0.715. CONCLUSION This study affirms the influence of carbon source on EPS production by selected oyster mushrooms, and reveals their antioxidant properties and potential applications in pest control. © 2021 Society of Chemical Industry.

Abstract
Lentinus squarrosulus (Mont.) is a wide edible mushroom widely consumed in Thailand. Ethanol extract was extracted from mycelium of L. squarrosulus No. 2 and Lentinus basidiocarp obtained from the local market at Mahasarakham province using 50% ethanol solvent. The effect of ethanolic extracts was tested for inhibition to some pathogenic bacteria. Antibacterial activity was tested by Poison food technique, it was found that 50 % ethanol extract from mycelium at concentrations of 10%, 15%, and 30% was effective to inhibit Bacillus cereus at the highest level (+++) and mycelium extract at the concentrations of 15% and 30% can inhibit Staphylococcus aureus with low level (+). But all concentrations of L. squarrosulus basidiocarp extract unable to inhibit the growth of B. cereus, Escherichia coli, Pseudomonas aeruginosa and S. aureus. Minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) of ethanolic extract from mycelium inhibit B. cereus was 125 mg/ml. The results indicate that the potential of L. squarrosulus mycelium is an excellent source of antimicrobial agents.

Abstract
Dracaena reflexa, a traditionally significant medicinal plant, has not been extensively explored before for its phytochemical and biological potential. The present study was conducted to evaluate the bioactive phytochemicals and in vitro biological activities of D. reflexa, and perform in silico molecular docking validation of D. reflexa. The bioactive phytochemicals were assessed by preliminary phytochemical testing, total bioactive contents, and GC-MS analysis. For biological evaluation, the antioxidant (DPPH, ABTS, CUPRAC, and ABTS), antibacterial, thrombolytic, and enzyme inhibition (tyrosinase and cholinesterase enzymes) potential were determined. The highest level of total phenolic contents (92.72 ± 0.79 mg GAE/g extract) was found in the n-butanol fraction while the maximum total flavonoid content (110 ± 0.83 mg QE/g extract) was observed in methanolic extract. The results showed that n-butanol fraction exhibited very significant tyrosinase inhibition activity (73.46 ± 0.80) and acetylcholinesterase inhibition activity (64.06 ± 2.65%) as compared to other fractions and comparable to the standard compounds (kojic acid and galantamine). The methanolic extract was considered to have moderate butyrylcholinesterase inhibition activity (50.97 ± 063) as compared to the standard compound galantamine (53.671 ± 0.97%). The GC-MS analysis of the n-hexane fraction resulted in the tentative identification of 120 bioactive phytochemicals. Furthermore, the major compounds as identified by GC-MS were analyzed using in silico molecular docking studies to determine the binding affinity between the ligands and the enzymes (tyrosinase, acetylcholinesterase, and butyrylcholinesterase enzymes). The results of this study suggest that Dracaena reflexa has unquestionable pharmaceutical importance and it should be further explored for the isolation of secondary metabolites that can be employed for the treatment of different diseases.

J Food Biochem 2021; 45:e13979. [PMID: 34698374 DOI: 10.1111/jfbc.13979] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 09/10/2021] [Accepted: 10/10/2021] [Indexed: 12/22/2022]
Abstract
The current research work was designed to investigate the protective effects of white button mushroom (Agaricus bisporus) against 7,12-dimethylbenz[a]anthracene (DMBA)-induced breast cancer. Breast cancer was induced in rats by the administration of a single dose of 50 mg/kg DMBA via gavage. The rats were divided into four groups: G1 (negative control group), G2 (positive control group), G3 (rats receiving mushroom extract), and G4 (rats administered with doxorubicin). The mushroom extract significantly (p < .001) improved the activity of antioxidant enzymes in carcinogenic rats. Moreover, the mushroom extract also prevented the increase in the concentration of tumor biomarkers that are CEA, CA 15.3, and CRP in experimental rats. Liver function enzymes were also raised in G2 and G4 compared with G3. Besides, the RBCs and Hb were also reduced significantly in G4 while in G3. The mushroom extract effectively controlled the level of RBCs and Hb. An improvement in lipid profile was also measured in mushroom extract receiving rats. Conclusively, the mushroom extract alleviated DMBA-induced breast cancer potentially via improving antioxidants, reducing lipid peroxidation, and decreasing tumor biomarkers. PRACTICAL APPLICATIONS: The present research study examined the antitumor potential of white button mushroom. The mushroom effectively prevented the increase in tumor biomarkers, reduction in antioxidant enzymes, and increase in lipid peroxidation in rats with DMBA-induced breast cancer. The mushroom can be used as a potential source to prevent breast cancer and further research can be conducted to explore its anticancer mechanisms.

[PMID: 34058312 DOI: 10.1016/j.jep.2021.114253] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/14/2020] [Revised: 04/28/2021] [Accepted: 05/08/2021] [Indexed: 06/12/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Khaya grandifoliola is a well-known tree species in Africa with a conservation status of 'vulnerable' due to its overexploitation by the wood industry. Several studies have recorded numerous ethnobotanical uses of this plant, as well as the scientific validation of the efficacy of extracts from different plant parts used for the treatment of various ailments. However, this useful information is scattered throughout the literature and thus there is no opportunity to identify the existing knowledge gaps. AIM OF THE STUDY This review aims to highlight the medicinal importance of Khaya grandifoliola including its known phytochemistry, biological activities and toxicology, to encourage a refocused conservation strategy since all current efforts are geared towards maintaining its continuous supply to the wood industry. MATERIALS AND METHODS Articles on K. grandifoliola were sourced from online databases such as Google Scholar, Medicine, PubMed, Science Direct, Scopus, SciFinder and other science journal websites up to May 2020. The search was conducted using various combinations of keywords such as biotechnological uses, biological activity, ethnobotany, ethnomedicine, indigenous uses, pharmacological activity, phytochemistry, proximate composition, toxicity, and traditional uses of K. grandifoliola. All downloaded articles were screened to determine their relevance to the scope of the review and the selected papers were included. RESULTS The review revealed a host of ethnomedicinal uses such as anticancer, antidiabetic, antimicrobial, anti-sickling, anti-ulcerogenic, and hepatoprotective, many of which are supported by scientific data. More importantly, toxicity tests revealed that many of the extracts are safe at various therapeutic doses. Important knowledge gaps that should be explored include phytochemical characterization and validation of some ethnobotanical claims on the folkloric usage of the plant. CONCLUSIONS Notwithstanding the importance of K. grandifoliola in the wood industry, this review reveals that its use as a medicine is equally important. Its medicinal uses are also well supported with scientific studies as well as favourable toxicological studies though some scientific knowledge gaps require further studies.

Acute toxicity of aqueous extract of Ambrosia arborescens Mill. on biochemical and histopathological parameters in rats. Toxicol Res 2021; 38:225-233. [PMID: 35419274 PMCID: PMC8960535 DOI: 10.1007/s43188-021-00106-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 08/18/2021] [Accepted: 09/07/2021] [Indexed: 10/20/2022] Open
Abstract
Medicinal plants play an important role in the management of various diseases, so their use has become widespread. However, in some cases the population uses plant species regardless of the toxicity they may possess. The objective of this study was to evaluate the acute toxicity of aqueous extract from the leaves of Ambrosia arborescens Mill. on the biochemical and histopathological parameters of albino Holtzman rats. To do this, the leaves of A. arborescens were collected in the province of Julcan, La Libertad Region-Peru. OECD (Organisation for Economic Cooperation and Development) guideline 423 was conducted, forming experimental groups of 10 animals each one (5 males and 5 females): Group I (Control), which received 2 mL physiological saline solution (SSF 0.9%), Groups II and III (A. arborescens-300 and A. arborescens-2000), which were given the aqueous extract leaves of A. arborescens in a single dose of 300 and 2000 mg/kg/day, respectively. On the 14th day of exposure, biochemical (creatinine, ALT and AST) and histopathological parameters were measured. The results show that the aqueous extract of A. arborescens at the dose of 2000 mg/kg produces an increase in biochemical parameters which is related to histopathological analysis of liver and renal tissue with mild congestion. The study concludes that the aqueous extract leaves of A. arborescens has a LD50 greater than 2000 mg/kg and produces mild congestion in kidneys and liver, but showed no significant toxicological changes in the other albino Holtzman rats organs.

Abstract
PURPOSE Coconut water is used in folklore medicine for oral rehydration, treatment of childhood diarrhoea, gastroenteritis and cholera, and is also known to possess antioxidant properties. OBJECTIVE In this study, we examined the ameliorative potentials of coconut water on carbon tetrachloride (CCl4) induced toxicity in rats. MATERIALS AND METHODS Rats were randomly assigned into separate cages according to the sex of 5 groups. Groups 2-5 were intraperitoneally injected a single dose of 1 mL/kg CCl4 diluted in olive oil. Only 3, 4 and 5 were orally given 2, 4, 6 mL/kg coconut water respectively, whereas groups 1 and 2 received distilled water. RESULTS Treatment with coconut water significantly (p < 0.05) increased red blood cell, packed cell volume, haemoglobin, high-density lipoprotein, glutathione, superoxide dismutase, catalase, total protein, and albumin compared to the negative control in both sexes of the rats. Furthermore, platelets, white blood cells, urea, low-density lipoprotein, triglyceride, total cholesterol, malondialdehyde, bilirubin, alkaline phosphatase, alanine and aspartate transaminases decreased significantly (p < 0.05) compared to the negative control in both male and female rats. CONCLUSION Thus, coconut water supplementation may reverse CCl4 induced toxicity and distortions on haematological parameters, lipid profile and antioxidant enzymes, liver and kidney biomarkers in rats.

Abstract
OBJECTIVE This study aimed at evaluating the bioactive constituents and the toxicological profile of the aqueous fermented seed extract of P. macrophylla. MATERIALS AND METHODS The chemical constituents of fermented P. macrophylla were assessed using GC-MS. For acute toxicity study, one-time doses of up to 5000 mg/kg of the extract were orally administered to male and female rats whereas 200, 400 and 800 mg/kg of the P. macrophylla extract were orally administered daily for 14 days in sub-acute toxicity investigation. Biochemical, haematological and lipid profiles were assessed following standard methods. RESULTS Bioactive compounds such as citronellol and oxirane, tetradecyl- (hexadecylene oxide) were identified in the extract. In acute toxicity test, no death or sign of toxicity was identified. For sub-acute study, ALT decreased significantly (p<0.05) while HDL-C had dose-dependent increases. No effect (p<0.05) on haematological parameters except on platelets was found. No histopathological changes were observed. CONCLUSION Our results demonstrated that the extract of fermented P. macrophylla caused no toxic effects in the rats at the tested doses. Therefore, they may be termed safe for consumption and therapeutic uses.

Toxicol Res 2019; 36:227-238. [PMID: 32685427 DOI: 10.1007/s43188-019-00021-5] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2019] [Revised: 06/24/2019] [Accepted: 06/25/2019] [Indexed: 01/21/2023] Open
Abstract
Solanum aethiopicum is used in ethnomedicine for the treatment of overweight, constipation and anaemia. This study evaluated the ameliorative effect of aqueous leaf extract of S. aethiopicum on phenylhydrazine-induced anaemia in rats. Acute toxicity was determined in male and female rats (n = 5/group/sex) by oral administration of single dose of up to 5000 mg/kg of the S. aethiopicum extract. The experimental rats were randomly grouped into five (5) groups of 6 rats each. Group (i) served as normal control, group (ii) negative control, group (iii) standard drug-5 mg/kg ferrous sulphate, groups (iv) and (v), 200 and 400 mg/kg of S. aethiopicum extract respectively. Phenylhydrazine (PHZ) was administered intraperitoneally at the dose of 50 mg/kg body weight for two consecutive days to groups (ii-v). After 14 days, the rats were sacrificed; blood, liver and kidney were collected. The haematological, lipid profile, liver and kidney function parameters were determined and the histopathology of the liver and kidney were examined. In acute toxicity study, no signs of toxicity or death were recorded. The study shows an observable significant (P < 0.05) increase in packed cell volume, haemoglobin and red blood cell counts at 400 mg/kg S. aethiopicum extract in both the male and female rats when compared to other groups. Solanum aethiopicum extract at the dose of 400 mg/kg reduced aspartate aminotransferase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), urea, creatinine and chloride. The results of this study lent credence to the use of S. aethiopicum leaf as an anti-anaemic tonic with a wide margin of safety and hepato/reno-protective potentials.
