punarnava :

Phytochemistry:

- Plant has yielded Boerhaavic acid, punarnavine, potassium nitrate, tannins, phlobaphenes.

- Root yields alkaloids (punarnavine), rotenoids (boeravinones A-F), flavonoids, amino acids, lignans (liriodendrons), ß-sitosterols and tetracosanoic, esacosanoic, stearic, and ursolic acids.

- Seeds yield fatty acids and allantoin.

- Ash analysis yielded potassium, magnesium, sodium, calcium, nitrate, phosphates, silica and sulphates.

- Studies have yielded ß-sitosterol, a-2-sitosterol, palmitic acid, tetracosanoic, hexacosonoic, stearic, arachidic acid, urosilic acid, among others.

- Phytochemical screening yielded flavonoids, alkaloids, glycosides and sterols in the alcoholic root.

- Study of methanol extract of roots isolated five new and four known rotenoids.

- Study of yielded alkaloids, tannins, flavonoids, saponin, terpenoid and phenols, and absence of cardiac glycoside in ethanol, chloroform, and petroleum ether extracts. Flavonoids (5.61 g/100g) and phenols (2.471 g/100g) were higher than alkaloids (0.232 g/100g).

- Study of ethanolic extract of leaves uridine (uridine triacetate) (1), quercetin 3-O-α-D-rhamnoside (2), eupalitin 3-O-β-D- galactopyranoside (3), 3-O-ß-D-glucopyranosyl sitosterol (4), boeravinone B (5), ß-amyrin (6), ß-amyrin acetate (7), and ß-sitosterol (8).
