Dicentra Canadensis: From 1 Different Sources

Walp.

Family: Papaveraceae.

Habitat: The Himalayas from Kumaon to Khasia Hills. Cultivated in Indian gardens.

English: Squirrel Corn. (A related species, Corydalis cucullaria, known as Turkey Pea, occurs in Canada and the USA.)

Action: Diuretic, alterative, anti- scrofula. Used for torpid and sluggish conditions, menstrual disorders and diseases due to vitiated blood. Also employed as a sedative for the relief of paralysis agitans and other muscular tremors.

A large number of physiologically active isoquinoline alkaloids have been isolated from the tubers of many species of Dicentra, but the use of Corydalis is not linked with the alkaloids they contain, only bulbocapnine, present in the tubers, exhibits therapeutic activity. It produces catalepsy in mammals and possesses sympathetic as well as parasympathetic central effects.

It has been employed for the relief of paralysis agitans and other muscular tremors, vesticular nystagmus and similar conditions.

The root contains protopine, cory- deline, bulbocapnine, cancentrine, de- hydrocancentrines A and B. Bicucul- line (an isoquinoline alkaloid) isolated from the tuber of Dicentra cucullaria, is a centrally-acting, spasmogenic antagonist of GABA.

Action: Astringent, haemostatic, antirheumatic, diuretic. Used for diarrhoea, kidney disorders, bronchitis and for bleeding piles, wounds, bruises. Essential oil— used in bronchial catarrh and cystitis.

The extracts of the plant gave ses- quiterpenes, beta-santalen, beta-hima- chalene, cuparene, alpha-curcumene, gamma-cadinene.

The petroleum ether and ethanolic extracts of aerial parts exhibit significant anti-inflammatory activity.

Aqueous extract of powdered plant produces fall in blood pressure, depresses the heart and increases respiration in animals.

The essential oil, obtained from aerial parts in Japan, is found to contain 47 volatile compounds of which 91.0% are terpenoids. The leaves contain cumu- lene derivatives.

For preparing plant extract as a drug, the volatile oil is removed from a hot aqueous extract and the residue is filtered and concentrated to 24% or 60% of dry matter content. The 6% dry matter extract contains flavones 0.83, tannins 0.52, reducing sugars 6.37 and total sugars 12.6%. The extract is anti- inflammatory, analgesic, bactericidal and fungicidal.... erigeron canadensis
