Abstract

fetched live from OpenAlex

Extracts of natural plants contain several chemical groups with various biological activities. This work aimed to evaluate the antioxidant, anthelminthic activities and determining the secondary metabolites, mineral and histological elements of Ocimum gratissimum from Democratic Republic of the Congo used for various culinary and therapeutic purposes. Primo Star 200® microscope was used for microscopic analysis further thin layer chromatography and X-ray fluorescence were used for chemical analysis. Antioxidant and anthelminthic activities were evaluated with DPPH° radical scavenging method and the rate of Benhamia rosea death, respectively. Spiral vessels, group scleritis, sclerotic fiber, pollen seed, stomata, hairs cells were found by Powder microscopic analysis. Secondary metabolites such as polyphenols (tannins, flavonoids, anthocyanins, leuco anthocyanins), alkaloids, steroids, terpenoids and various mineral elements (K, Ca, Cl, P, S, Mg, Na, Zn, Cu, Mn, Fe, etc.) were found in O. gratissimum leaves. Aqueous extract showed a high antioxidant activity with an IC50 of 25.7 ± 1.03 μg/mL. Aqueous extract of O. gratissimum leaves is a good antioxidant and it has an interesting anthelmintic activity.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
