Pharmacological study of trunk bark of Acacia nilotica var adansonii (Guill et Perr).o Ktze (Mimosaceae): Assays, antioxidant and antispasmodic activities
Bibliographic record
Abstract
Aim of this study was to evaluate in vitro polyphenols content, antioxidant and antispasmodic properties of the aqueous extract and fractions of the trunk bark of Acacia nilotica. According to a survey conducted in rural Burkina Faso, Acacia nilotica var. adansonii (Guill and Perr). Ktze reported to be widely used in the treatment of gastrointestinal diarrhoea and parasitosis. A maceration of the powder of the trunk bark of the plant was carried out. Then the aqueous macerate obtain, was fractionated with dichloromethane, butanol and ethyl acetate successively. The phenolic compounds of the aqueous extract, butanol and ethyl acetate fractions was determinated. The antioxidant activity of aqueous extract and fractions was evaluated by the DPPH, ABTS and FRAP tests. The contractility test on smooth muscle was realized according to Magnus method. Assay of the extracts revealed a high content of polyphenols, tannins and flavonoids. The aqueous extract, the butanol fraction and the ethyl acetate fraction demonstrated a high antioxidant capacity. Aqueous extract showed a better antispasmodic effect of acetylcholine contraction induction at 1 μM (IC50 = 13.02 μg / mL) and for BaCl2 at 160 μg / mL (IC50 = 117.2 μg / mL). The aqueous extract of Acacia nilotica and his fractions had antioxidant properties. Only aqueous extract proven better antispasmodic property. Hence its use in traditional medicine in the treatment of diarrhoea. Keywords: Acacia nilotica, Antioxidant, Antispasmodic

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
