Information on echicaoutchin:

In addition, there are present oxalate of calcium, fatty acid, crystallizable acid, and several fatty resinous substances called: Echicaoutchin (C25H40O2); echicerin (C30H48O2); echitin (C32H52O2); echitein (C42H70O2); echiretin (C35H56O2). These substances closely resemble resins obtained from other sources. Doubtless, the bark, if employed in medicine, will be either used in substance or in the form of tincture or fluid extract, as the proximate principles can not become of much commercial importance.
