Populus Nigra: From 1 Different Sources

Linn. var. italica Kochne.

Family: Salicaceae.

Habitat: North-western Himalaya at 900-3,700 m.

English: Black Lombardy Poplar.

Action: Bark and balsam from leaf bud— used for cold. Bark— depurative. Leaf bud—antiseptic, anti- inflammatory.

The bud exudate contains dimethyl- caffeic acid, which was found active against herpes simplex virus type 1.

A 50% ethanol extract of a mixture of flowers and buds showed 11% inhibition of enzymatic conversion of testosterone into 5 alpha-dihydrotesterone and 4-androstene-3,17-dione. The extract was partitioned between ethylac- etate and water and the resultant ethy- lacetate fraction contained the active compounds, pinobanksin, demethyl- quercetin and pinocembrin. It exhibited 15% inhibitory activity on the enzyme. Pinocembrin was the most potent, almost equal to estradiol, which was used as a control.

The bark of all Populus species contains, phenolic glycosides, salicin and populin (salicinbenzoate). Tannins are also present (5-9%).

Both salicin and populin cause elimination of uric acid. Salicin is antiperi- odic and is used like quinine in intermittent fever, also in coryza, rheumatism and neuralgia.

Action: Berries and root bark— mild laxative and used in the treatment of respiratory catarrh. Berries—refrigerant, given during convalescence.

The fruit contains invert sugar, pectin, fruit acids (including malic and citric acid), ascorbic acid, and fla- vonoids (including rutin). Leaves contain flavonoids, including rutin (26%). Root bark contains calcium malate; the bark of branches contains tannins, phlobaphenes, a sugar, a phy- tosterol, ceryl alcohol, fatty acids and phosphoric acid.

An infusion of leaves causes a drop in blood sugar, sometimes diuresis and a reduction in arterial pressure. It shows no effect on glucosuria.
