EVALUATION OF ANTIOXIDANT POTENTIAL AND PHYTOCHEMICAL CHARACTERISATION OF PEEL EXTRACTS OF LUFFA ACUTANGULA AND LUFFA CYLINDRICA
Bibliographic record
Abstract
Luffa acutangula and Luffa cylindrica are popular vines belonging to the Cucurbitaceae family. They are extensively used as vegetables across the globe. Cucurbitaceae plants have played a major role in Indian medicinal systems and ethnopharmacology. Various plant parts have pharmacological properties viz. antioxidant, antiinflammation, antidiarrheal, anticancer, antiulcer and so on. These properties are due to phytochemicals present in the plants. Phytochemistry is the study of plant chemicals, particularly secondary metabolites. These metabolites are typically produced as a self-defence mechanism against insects, pests, pathogens, herbivores, ultraviolet exposure, and environmental hazards. The present study is aimed to identify and quantify certain phytochemicals which are known to be responsible for bioactivities. Peels are generally thrown away in culinary practice, but they are highly rich in phytochemicals. Peels of both plants have taken for the study and qualitative analysis of phytochemicals such as alkaloids, phenols, flavonoids, sterols, tannins, saponins, etc. were carried out. Plant extracts of different solvents were compared for antioxidant potential as well as total phenols and total flavonoids. Quantification of phenols and flavonoids was carried out as they are reported to have antioxidant potential. FRAP assay was performed to check the capacity of plant extract to scavenge free radicals. The correlation of phenols and flavonoids was carried out with antioxidant results to establish the fact. The plant extracts' total phenolic content was 66-357 mg gallic acid equivalent. The highest flavonoid content was found in methanol extracts of L. acutangula and L. cylindrica with values of 133.450 and 126.132 mg quercetin equivalent. FRAP assay concluded that methanol extracts of both plants have highest reducing power. TPC and TFC have shown strong positive correlation with FRAP assay. The phytochemicals and antioxidant potential of L. acutangula and L. cylindrica state that they possess valuable nutraceuticals. The pharmacological potential of the plants should be explored to maximum potential.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
