Phytochemical screening and analysis -

Liver damage is typically assessed by determining serum transaminases AST and ALT and measuring total proteins. Liver injury caused by hepatotoxic drugs can result in elevated AST, ALT, and total protein levels [ 74 , 75 ].

Hepatocellular damage could increase cell membrane permeability and then lead to the release of aminotransferases into the bloodstream [ 76 , 77 ]. Since no significant alterations were detected in serum levels of these three markers of liver function, and histopathological analyses of the livers from treated animals did not show tissue changes, the findings from the present study suggest that administration of the extracts from the selected plant species did not cause liver damage.

Renal function is usually assessed by serum creatinine and urea levels and histopathological analysis of the kidney tissues. Its impairment is shown by raised serum creatinine levels and urea [ 79 ]. Urea is a marker of acute renal dysfunction, the first acute marker following renal injury [ 80 ].

In this study, a significant increase in the level of urea was observed in the A. hockii treated group, suggesting a mild renal injury. This finding is also supported by the excessive urination observed from the same group.

In this study, mortality was registered from the A. coriaria treated group only, where one rat died. In spite of this general classification, signs of toxicity were detected in the organs from the A.

coriaria treated group and could be considered somewhat toxic. This is the first report of acute toxicity study of all the selected plant species to the best of our knowledge.

The selected medicinal plants have promising antimycobacterial activity, and low toxicity, except A. coriaria, which appears to be moderately toxic. The findings of this study justify the ethnopharmacological use of the plant parts of the selected plant species to treat tuberculosis and other diseases whose symptoms closely resemble tuberculosis.

Chronic toxicity studies of the selected plant species will be necessary to support their use further. Furthermore, all the selected plant species in this study are potential candidates for isolation and characterization to identify antimycobacterial compounds responsible for their activities.

Abstract Background Tuberculosis TB is one of the leading causes of death globally, and the rise in drug-resistant forms of TB has become a significant threat. Results The extracts contained alkaloids, flavonoids, tannins, saponins, steroids, terpenoids, resins, cardiac glycosides, phenolic compounds, and coumarins.

Conclusion Phytochemical screening of the extracts revealed the presence of alkaloids, tannins, saponins, flavonoids, steroids, terpenoids, resins, cardiac glycosides, phenolic compounds, and coumarins. Materials and methods Selection criteria The medicinal plant species considered in the present study were selected based on their high frequency of mention registered from three or more different ethnobotanical surveys reported in the literature for the treatment of TB.

Plant material Plant parts from Acacia hockii De Wild. Extraction process For organic extractions, the powdered plant part 60 g of each of the following: A. Antimycobacterial activity M. tuberculosis strains and preparation of inoculum Two experimental mycobacterial strains from a WHO proficiency testing panel were used: a fully susceptible laboratory strain H 37 Rv and a known MDR-TB strain.

Determination of minimum inhibitory concentration MIC and minimum bactericidal concentration MBC The MIC and MBC of the crude extracts against both the susceptible H 37 Rv and MDR-TB strains were determined using microplate alamar blue assay MABA protocol with minor modifications [ 25 ].

Experimental animals Adult female Wistar albino rats aged 8—10 weeks were used for the acute toxicity study. Acute toxicity assay Acute toxicity study was performed in line with the OECD standard guidelines for using animals in scientific research, Guideline No.

Hematological analysis Blood samples were stored in EDTA tubes, and hematological analysis was performed using an automated hematology analyzer SYSMEX XN-L SN Biochemical analysis Dry tubes containing the collected blood samples were centrifuged at rpm for 15 min to obtain the serum.

Histopathological analysis The vital organs collected from the animals were washed with saline solution 0. Results Phytochemical constituents The extracts contained alkaloids, saponins, tannins, flavonoids, steroids, resins, terpenoids, cardiac glycosides, phenolic compounds, and coumarins Table 1.
