Abstract

Different extraction methods were analyzed. Extraction with ethanol gradual alternation was chosen as more optimal.A technique of quantifying the flavonoids equivalent to luteolin in Inula britannica herb was suggested. It allows a determination of the flavonoid quantitative order in the presence of other compounds; it does not require any expensive equipment, and it is simple in use. The flavonoid content in Inula britannica herb, which grows in the Volgograd region, was (0,94 ± 0,003) %.Validation proved that the proposed technique can be used for quality control of studied herbal raw material.

Keywords
