Anthocyanin profiling of wild maqui berries (<i>Aristotelia chilensis</i> [Mol.] Stuntz) from different geographical regions in Chile

Three maqui genotypes exhibited significantly higher anthocyanin content than the others, as measured by pH differential method and high-performance liquid chromatography-mass spectrometry. Significant genetic diversity was noted within each ecological population. ISSR-PCR analysis provided a fingerprinting approach applicable for differentiation of maqui genotypes.
