Aloin, Barbaloin

Aloinplant extracts are irritant laxative materials contained in the yellow sap ofaloe, which is a component of the AnthraquinoneComplex. This plant is always regarded as a beauty ingredient both in China andforeign countries.
Aloin plant extract is not only used as a kind of anthraquinone but also suitable for pharmacy as a chemicalcomponent. The processes of aloin production,transport and storage are studied with a transmission electron microscope usingthe lead acetate precipitate method for ultracytochemicallocalization of aloin in the leaf of aloearborescence Mill. The results showed that aloin wasproduced in the plastids of the assimilating tissue, transported through theplastid membrane to the surrounding endoplasmic reticulum and enveloped in thevesicles by the endoplasmic reticulum elements. The vesicles approached, andlater fused with, the plasmalemma, released theircontents into the apoplast through exocytosis and finally, reached the vascular bundle sheathby apoplastic translocation. Aloinplant extract was transported to the internal tangential wall of the vascularbundle sheath cell through endoplasmic reticulum vesicles, and reached thecytoplasm of the aloin cell by means of plasmodesmata. Finally, aloin wasstored in the vacuole of the cell in which it was produced.
The plant extracts extracted from aloes smells fragrant but tastes a littlebitter.
