A study of quantitative content of quercetin in the leaves of the schisandra chinensis
The article deals with the issues of determining the content of the dominant flavonoid in alcohol extracts from the leaves of Schisandra chinensis, which are not an official type of raw materials. The chromatodensitometric method (high-performance thin-layer chromatography) was used in the studies,...

The article deals with the issues of determining the content of the dominant flavonoid in alcohol extracts from the leaves of Schisandra chinensis, which are not an official type of raw materials. The chromatodensitometric method (high-performance thin-layer chromatography) was used in the studies, which allows not only to detect adsorption zones on the sorbent layer, but also gives a quantitative assessment of the resulting separation directly on the chromatographic plate. Pre-selected chromatography conditions (solvent system ethyl acetate-methanol-water (77 : 15 : 8), chromatographic plate «Sorbfil PTSH-P-А-UV», a method of extraction of the studied raw materials, extractant) at 365 nm allowed to develop a method of quantitative determination of quercetin in the leaves of Schisandra chinensis, a species introduced in the Republic of Bashkortostan.
