Definition

ChEBI: A C-glycosyl compound that is beta-D-glucopyranose in which the anomeric hydroxy group is replaced by a 4,5-dihydroxy-2-(hydroxymethyl)-10-oxo-9,10-dihydroanthracen-9-yl moiety (the 9S d astereoisomer).

Safety Profile

Poison by subcutaneous andintravenous routes. Moderately toxic by ingestion. Whenheated to decomposition it emits acrid smoke and fumes.A carthartic and purgative.

Purification Methods

Aloin forms the monohydrate as lemon yellow crystals on crystallisation from H2O (450g/1.5L) which has a lower m ~70-80o than the anhydrous substance. [Cahn & Simonsen J Chem Soc 2573 1932, Hay & Haynes J Chem Soc 3141 1956.]
