| There are a number of medicinally active phytochemicals isolated from hawthorn with most of the data generated in studies of those species that are native to Europe and Asia. Comparatively little is known about the North American, specifically the Mexican Crataegus species. The objective of this study was to evaluate phenolic compounds, flavonoids and antioxidant activity of extracts of flowers from six Mexican accessions of Crataegus in order to contribute to the chemistry of the Germplasm Bank accessions at the Universidad Autonóma Chapingo. Antioxidant activity was evaluated using DPPH (2,2-diphenyl-1-picrylhydrazyl) method and the flavonoids were identified by HPLC-MS. Quercetin- 3-O-glucoside, quercetin-3-O-rhamnoside, quercetin... |
