Flavonoids were recovered from shredded chamomile flowers (0,28-1,6 mm) by extn. with EtOH and assisted by (i) microwaves (240 W, 1 min; then 360 W, 30 mM) as well as (ii) ultrasounds (33 kHz, 320 W, 30 min). The exts. were analyzed quant. and qual. by using high performance liq. chromatog. coupled with electrospray ionization mass spectrometry. Method (i) was more effective than method (ii).
