Pomolic acid (PA) is a pentacyclic triterpenic acid isolated from apples by Brieskorn and Wunderer in 1967 [1]. Its highly relevant biological activity profile came recently into focus and there have been many reports on the content of PA in different plant sources [2]. Quite surprisingly, the general perception of low PA content in plants persists and this information hinders its broader investigation as a compound of pharmaceutical and nutraceutical potential. The main aim of the current work was quantitative determination of pomolic acid in apple pomace by two-dimensional heteronuclear NMR

Arachidomc acid is metabolised by cyclo-oxygenase and lipoxygenase enzymes in platelets. Cyclo-oxygenase produces the highly pro-aggregatory thromboxane A2 but the physiological significance of the lipoxygenase pathway in platelets remains uncertain. Arachidonic acid can also be converted to biologically active peroxides by free radical induced autoxidation, and previous studies have shown that such products generate large amounts of thrombin in platelet-free plasma, via their interaction with plasma lipoproteins.In the present study, we have investigated the procoagulant activities of platele
