Оптимизация процесса экстрагирования флавоноидов из травы мелколепестника канадского

We studied the influence of technological factors on the extraction of flavonoids from Conyza canadensis herb. Through experimenting we determined the conditions which ensure the maximum flavonoid fractional yield from Conyza canadensis herb (1,91 ± 0,003 %): grinding size 1 mm, boiling time 30 minutes, extractant 70% ethyl alcohol, ratio of raw material and extractive solvent 1:60, single extraction.
