Abstract
Phenolic compounds in winter savory (Satureja montana L.) extracts were analysed by HPLC with diode array detection on reversed phase, C8 columns. Gradient elution with acetonitrile‐acetic acid‐water mixture gave complete separation of all phenolic acids and flavanols of interest. The identified phenolic acids and flavanols, as well as tentatively identified phenolic acids in ethyl acetate and n‐butanol extracts, were quantified. Total content of phenolic acids in ethyl acetate and n‐butanol extracts was 47.59 and 96.70 µg/g, respectively. Flavanols, (±)‐catechin and (−)‐epicatechin were present in ethyl acetate extract in quantities of 622.47 and 16.29 µg/g, respectively, while n‐butanol extract contained these flavanols in extent of 239.08 and 199.82 µg/g.
