      Pajaneelin, the crystalline bitter principle of the bark ofPajaneelia Rheedii is strongly laevorotatory and yields on hydrolysis with dilute alkali molecular proportions ofp-hydroxy-cinnamic acid andd-fructose. Methylation and subsequent hydrolysis producesp-methoxy-cinnamic acid. It is a neutral compound. It is therefore an ester ofp-hydroxy-cinnamic acid withd-fructose. The occurrence of similar sugar esters is briefly reviewed.
