Exploring the Anthelmintic, Antioxidant, and Cytotoxic Potential of Khaya grandifoliola and Faidherbia albida Extract Combinations - In Vitro Studies on Heligmosomoides polygyrus and Caenorhabditis elegans

Sep 29, 2026

Soil-transmitted helminth infection remains a public health challenge in Chad, especially among school-age children. This in vitro study evaluated synergistic anthelmintic effects of combined extracts from Khaya grandifoliola and Faidherbia albida as used by traditional practitioners. Three extract combinations were tested on Heligmosomoides polygyrus and Caenorhabditis elegans, alongside antioxidant and cytotoxicity assessments. Results showed combination 2 (50%/50%) as most promising, with the greatest activity in nematocidal assays and measurable antioxidant profiles, supporting traditional therapeutic use while recommending further in vivo work.

Background: Soil-transmitted helminth infection is endemic in Chad and constitutes a public health problem, particularly among school-age children. The aim of this study was to evaluate the synergistic anthelmintic activity of the combined extracts ofKhaya grandifoliola and Faidherbia albida used in Chad by traditional practitioners for the treatment of soil-transmitted helminth infection. Methods: The anthelmintic tests using combinations ofK. grandifoliola and F. albida followed standard protocol. Combination 1 corresponding to 75% F. albida and 25% K. grandifoliola, Combination 2 corresponding to 50% F. albida and 50% K. grandifoliola, and Combination 3 corresponding to 25% F. albida and 75% K. grandifoliola. The nematocidal activity was assessed on Heligmosomoides polygyrus and Caenorhabditis elegans using the WMicroTracker. L3 larvae of H. polygyrus were obtained after 7 days of coproculture, and L4 of C. elegans. One hundred microliter concentrations of extracts, albendazole, and distilled water were brought into contact with 100μL of H. polygyrus suspension in a 96-well microplate incubated for 20h at 28°C in the WMicroTracker. The same procedure was adopted for C. elegans, but 180μL of OP50 and 19μL of C. elegans suspension were mixed with 1μL of extracts and incubated at 20°C in the WMicroTracker. The antioxidant activity was assessed by 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical, iron reducing power (Frap), hydrogen peroxide (H2O2), and nitric oxide (NO) . Cytotoxicity was tested on red blood cells. The phytochemical screening was conducted using both qualitative and quantitative methods. Standard procedures were followed to ensure accuracy and reliability. The analysis was aimed at identifying and measuring the bioactive compounds present. Results: Combination 2 (50% F. albida and 50% K. grandifoliola) was the most promising, with an IC50 of 0.26 and 0.003mg/mL, respectively, on H. polygyrus and C. elegans. This was followed by Combi

FAQs

What was the study aim regarding Khaya grandifoliola and Faidherbia albida?

To evaluate the synergistic anthelmintic activity of combined extracts of Khaya grandifoliola and Faidherbia albida used traditionally in Chad for soil-transmitted helminth infection.

Which extract combination showed the strongest anthelmintic potential in vitro?

Combination 2 (50% F. albida and 50% K. grandifoliola) was most promising, with the lowest reported IC50 values against Heligmosomoides polygyrus and Caenorhabditis elegans.

How were antioxidant and cytotoxic effects assessed?

Antioxidant activity was measured using DPPH, iron reducing power (FRAP), hydrogen peroxide (H2O2), and nitric oxide (NO). Cytotoxicity was tested on red blood cells, with phytochemical screening performed using qualitative and quantitative methods.
