Usage examples of glucoside.
From the bark of the stem and root of the apple, pear and plum trees, a glucoside is to be obtained in small crystals, which possesses the peculiar property of producing artificial diabetes in animals to whom it is given.
The seeds contain abundantly a demulcent oil, whilst the petals furnish a glucoside which is colourless unless treated with alkalies, when it becomes of a golden yellow.
The seeds themselves contain in the cotyledons and endosperm from 30 to 40 per cent of a fixed oil, of a light yellow colour, and about 25 per cent proteids, together with wax, resin, sugar, phosphates, acetic acid, and a small quantity of the glucoside Linamarin.
It has properties very similar to Black Mustard seeds, containing Sinigrin, a crystalline glucoside, which is decomposed in the presence of water by Myrosin, an enzyme found also in the root, the chief produce being the volatile oil Allyl, isothiocyanate, which is identical with that of Black Mustard seed.
Other constituents are a crystalline saponin- like glucoside, an amorphous, bitter glucoside, which is a modification of tannin, and is known as Ipecacuanhic acid, choline, resin, pectin, starch, sugar, calcium oxalate, odorous, fatty matter and a disagreeable-smelling volatile oil.
The assertion has been made that the bark contains glucosides which yield on hydrolysis Chrysophanic acid, but the evidence on this point is conflicting.
The seeds also contain the crystalline glucoside Sinalbin and the enzyme Myrosin, which unite to form a volatile oil, called Sinalbin Mustard Oil, used for various purposes, though not so pungent as that of Black Mustard.
The Bitter Almond seed also contains a ferment Emulsin, which in presence of water acts on the soluble glucoside Amygdalin yielding glucose, prussic acid and the essential oil of Bitter Almonds, or Benzaldehyde, which is not used in medicine.
Arum leaves give off prussic acid when injured, being a product of certain glucosides contained, called cyanophoric glucosides.
