Syringin is a natural substance which (Syringa vulgaris) occurs in the Commons lilac and was first isolated in 1841.

History and habitat

From the bark of the commons lilac isolated Alphons Meillet a substance, which he named in accordance with the purple color of the flowers Lilacin. Franz J. Bernays isolated the substance from leaves and green twigs of the same plant and named it based on the Latin name Syringin. It is also found as eleutheroside B in the Siberian ginseng ( Eleutherococcus senticosus ).

Properties

Syringin forms colorless needle-like crystals which melt at 192 ° C. Chemically, it is the glycoside with sinapyl alcohol as aglycone and glucose. Structurally and in particular derived from them: syringol, Syringaalkohol, syringaldehyde, syringic acid and acetosyringone, structurally also: sinapyl alcohol, Sinapinaldehyd and sinapic.
