4. Phytochemicals specific to the plant and their action.

Triterpenoids (Cocciniosides): These are unique saponins identified in Coccinia grandis. They are primarily responsible for the potent Antidiabetic and Hypoglycemic activity by increasing glucose uptake and inhibiting glucose absorption from the intestine.

Flavonoids (Quercetin, Kaempferol): These compounds are powerful Antioxidants that help protect pancreatic beta-cells from oxidative damage. They contribute to the plant's Anti-inflammatory and Antipyretic properties.

β-Sitosterol: A phytosterol with documented Hypolipidemic and Antidiabetic effects. It helps in reducing cholesterol levels and also contributes to the anti-diabetic action.

Pectin and Dietary Fiber: Found in the fruit, these constituents are responsible for the Laxative effect. They add bulk to stool and also help slow down sugar absorption in the gut.

Tannins and Alkaloids: These contribute to the plant's Antimicrobial and Astringent properties, which support its traditional use in wound healing and skin infections.
