Bala (Sida cordifolia) (Sida cordifolia)

Bala (Sida cordifolia) is a medicinal herb primarily valued for its bioactive alkaloid content rather than conventional macronutrient density. Key bioactive compounds include: Ephedrine and pseudoephedrine (0.085–0.15% in aerial parts), which are the primary sympathomimetic alkaloids responsible for bronchodilatory and stimulant effects; Vasicine (peganine) and vasicinone, quinazoline alkaloids present at approximately 0.5–1.2% in leaves, contributing to respiratory and anti-inflammatory activity; Hypaphorine, a tryptophan-derived alkaloid found in seeds; Choline and betaine, quaternary ammonium compounds supporting cellular metabolism. Phytosterols including beta-sitosterol (estimated 0.3–0.6% dry weight) contribute to anti-inflammatory bioactivity. Fatty acids in seeds include palmitic acid (~20%), stearic acid (~5%), oleic acid (~30%), and linoleic acid (~35%), providing a moderate unsaturated fat profile. Saponins are present at approximately 1.5–3% dry weight, enhancing bioavailability of co-administered compounds through intestinal permeability modulation. Minerals detected include calcium (~180 mg/100g dry weight), magnesium (~95 mg/100g), potassium (~310 mg/100g), and iron (~12 mg/100g). Crude protein content ranges from 12–18% dry weight in leaves, with a notable presence of hydroxyproline supporting connective tissue metabolism. Crude fiber content is approximately 8–12% dry weight. Tannins (~2.5%) and flavonoids including quercetin glycosides contribute antioxidant activity. Bioavailability note: Alkaloid absorption is enhanced when taken with warm water or milk (traditional Anupana); fat-soluble phytosterols show improved absorption with lipid-containing carriers.
