Influence of the extraction mode on the yield of hyperoside, vitexin and vitexin‐2′′‐<i>O</i>‐rhamnoside from <i>Crataegus monogyna</i> Jacq. (hawthorn)

Abstract

A microwave protocol combined with isocratic HPLC analysis is proposed for the rapid screening of plant materials collected in different environmental conditions in order to evaluate the productivity of Crataegus monogyna Jacq. and to find out the best ecological conditions to cultivate hawthorn in Northern Italy.
