Biologically active compounds from Viola brachyceras herb

The composition of phenolic compounds of short-spurred violet herb Viola brachyceras Turcz. was investigated. Thirteen compounds of flavonoid structure were identified by high-performance liquid chromatography as tannin; epicatechin; gallic, chlorogenic, caffeic, chicoric, ferulic, neochlorogenic, and cinnamic acids; and the flavonoids rutin, apigenin, luteolin, and naringenin. The contents of 20 elements (Na, Mg, Al, Si, P, S. Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, and Ba) were measured by x-ray fluorescence spectrometry. Phenolic compounds and the elemental composition of V. brachyceras were reported for the first time. The results were of interest for further investigation of the pharmacological properties of V. brachyceras as a valuable raw material for producing new drugs.
