6. Mechanisms of Action

6.1 Antidiabetic: Alpha-Glucosidase Inhibition and Insulin Sensitisation

The leaf extract has demonstrated significant alpha-glucosidase inhibition, delaying the digestion and absorption of carbohydrates in the gut and managing postprandial hyperglycemia . Preclinical and clinical evidence suggests multiple pathways, including enhanced insulin sensitivity, improved pancreatic beta-cell function, and reduced hepatic glucose output . Polyphenols like chlorogenic acid are known to inhibit glucose-6-phosphatase, reducing hepatic glucose output. Clinical trials demonstrate FBG reduction by -5.6 mg/dL in prediabetic adults after 12 weeks of supplementation .

6.2 Calcium Channel Blockade

Extracts exert a spasmolytic and vasodilatory effect, which is rationalised by a calcium channel blocking mechanism. This action contributes to its antihypertensive effects by relaxing vascular smooth muscle, thus lowering blood pressure .

6.3 Antioxidant Activity

The plant's exceptionally high content of polyphenols and flavonoids (e.g., quercetin, kaempferol) provides a strong capacity to scavenge free radicals and protect cells from oxidative stress. A single 500 mg dose of leaf extract rapidly enhanced plasma antioxidant status using FRAP and TEAC assays within 30 minutes, while concurrently reducing the lipid peroxidation marker, malondialdehyde (MDA) .

6.4 Anti-Inflammatory and Immunomodulatory Activity

Moringa modulates inflammatory pathways by inhibiting the expression of key pro-inflammatory cytokines such as TNF-alpha, IL-6, and IL-1 beta . This is mediated by compounds like isothiocyanates and flavonoids. In a clinical trial of rheumatoid arthritis patients, 40.50 mg/kg body weight/day of Moringa extract for one month resulted in a significant decrease in IL-6 levels and simplified disease activity index scores . Moringa polysaccharides also enhance the immune response by increasing pinocytic rate and production of reactive oxygen species (ROS), nitric oxide (NO), IL-6, and TNF-alpha .
