Preliminary research of polyphenolic compounds from<br />
Viola Tricolor l. (Violaceae)<br />
ANCA TOIU, ILIOARA ONIGA, M. TĂMAŞ<br />
Summary<br />
We have initiated a phytochemical study of the polyphenolic compounds<br />
(flavonoids, polyphenol carboxylic acids, tannins, anthocyanins, proanthocyanins)<br />
contained in the aerial parts of Viola tricolor L., harvested from different regions and<br />
time periods. The qualitative analysis and the quantitative determinations were made<br />
using chromatographic and spectrophotometric methods. We have identified rutoside<br />
and caffeic acid, and after hydrolysis, quercetol and kaempferol as flavonoid<br />
aglycones. In all five analysed samples, we have determined the content in flavonoids<br />
(0,508-1,992%), polyphenol carboxylic acids (0,098-0,687%), tannins (0,798-<br />
2,821%), anthocyanins (12,353-28,643 *10 -3 %) and proanthocyanins (0,071-0,135%).<br />
Key words: Viola tricolor L., polyphenolic compounds, flavonoids, tannins<br />
