The yield of extractive substances, antioxidant activity, as well as total
phenolic and total flavonoid contents of aqueous-ethanolic extracts obtained
from aerial parts of Galium mollugo L. by different extraction techniques
(maceration, reflux and ultrasonic extraction) were reported. The antioxidant
activity of extracts was tested by measuring their ability to scavenge a
stable DPPH free radical, while the total phenolic and total flavonoid
contents were determined according to the Folin-Ciocalteu procedure and a
colorimetric method, respectively. The Duncan?s multiple range tests were
used to evaluate if there were significant differences among yields of
extractive substances, total phenolics, total flavonoids and EC50 values for
the extracts obtained by different extraction techniques. The extracts
obtained by the reflux extraction contained higher amounts of extractive
substances, as well as phenolic and flavonoid compounds, and showed a better
antioxidant activity than those obtained by the two other recovering
techniques.
