Which chemical test is used for detection of anthracene glycosides?

Borntranger’s test: Powdered leaves of Senna are boiled with dilute sulphuric acid. Filtered and cooled. The filtrate is extracted with chloroform or benzene and dilute ammonia is added to it. The ammonical layer becomes pink to red due to the presence of anthraquinones derivative.

What are the therapeutic uses of anthraquinone glycosides?

Besides their utilization as colorants, anthraquinone derivatives have been used since centuries for medical applications, for example, as laxatives and antimicrobial and antiinflammatory agents. Current therapeutic indications include constipation, arthritis, multiple sclerosis, and cancer.

Which test is used for identification of anthraquinone glycosides?

Bromine test: is used to identify anthraquinone glycosides in general. Its procedure is: to two ml of the extract add an equal volume or an excess of freshly prepared solution of bromine. Record the color. Nitric acid test: is specific identification of the anthraquinone glycosides.

What are anthracene glycosides?

ANTHRACENE GLYCOSIDES. A number of glycosides in which the aglycones are anthracene derivatives occur as the phannacologically active constituents of several cathartics of plant origin. The principal ones among these vegetable cathartics are: Cascara, Rhubarb, Aloe, and Ser.na.

What are the test for glycosides?

Kedde test: A solution of glycosides is treated with a small amount of Kedde reagent (Mix equal volumes of a 2% solution of 3, 5 dinitrobenzoic acid in menthol and a 7.5% aqueous solution of KOH). Development of a blue or violet colour that faded out in l to 2 hrs shows it presence of cardinoloids.

Which type of glycosides gives foaming test?

saponin solution → appearance of ruptured red blood cells →the presence of sapnonin glycoside. (ii) Foam test : 1 gm of sample drug + 10 to 20 ml of water →well shaked →generation of froths → the presence of saponins. 5.

What are glycosides used for?

Cardiac glycosides are medicines for treating heart failure and certain irregular heartbeats. They are one of several classes of drugs used to treat the heart and related conditions. These drugs are a common cause of poisoning.

Which drug contains anthraquinone?

ANTHRAQUINONES AS DRUGS Examples of anthraquinone derivatives that are used in the clinical practice include anthra- cyclines and related anticancer drugs, natural hydroxyanthraquinones used mainly as laxatives, and the antiinflammatory drug diacerein (Table I; Figs.

How do you detect glycosides?

(i) Haemolysis test : A drop of blood on slide + few drops of aq. saponin solution → appearance of ruptured red blood cells →the presence of sapnonin glycoside. (ii) Foam test : 1 gm of sample drug + 10 to 20 ml of water →well shaked →generation of froths → the presence of saponins.

What are anthraquinones used for?

Fungal anthraquinones are widely used as dyes for natural and synthetic fibers. Further, anthraquinones also find applications as semiconductors in microelectronics. Many of them possess antibacterial, antiparasitic, insecticidal, fungicidal, and antiviral properties. They are also used as anticancer agents.

What are the different types of cardiac glycosides?

Clinically used cardiac glycoside-based drugs are digoxigenin, digoxin, deacetyl glucoside, and venomous glucosinolate K, which have similar pharmacodynamic characteristics, but different pharmacokinetic properties and drug effects.
