✦ Synopsis

Purified extract of Vaccmtum myrtrllus containing fifteen different anthocyanms was subJected to various amblent conditions m the sohd state and m mild and strong acid solution m order to force the degradation of these pharmacologically active components hqmd chromatographlc analyses of the samples showed that the degradation of the anthocyamns under drastic condltlons (7 days at 100Β°C and 15 days at WC, pH 1 5) dtd not produce important changes m the relative anthocyamn composition Under these conditions only the elgenvector proJection statIstica method can show preferential degradation of anthocyanm arabmosldes m comparison with galactosldes and, to a lesser extent, with glucosldes Mild condltlons (solid samples exposed for 15 days m au and daylight or 15 days at 50Β°C) did not produce significant degradation of the anthocyanms
