Along with solid anthocyanins white substance was found, which may suggest a presence of contaminants.

However, this procedure cause also extraction of different phenolic compounds so it is necessary to use SPE, HPLC or column chromatography treatment.

By using HPLC with appropriate detectors it is also possible to identify separate anthocyanins.

Colour of solid anthocyanins was black with shade of violet and absorption spectrum indicates that anthocyanins did not decompose during the process so this method seems to be efficient. Screening plants of European North-East Russia for ecdysteroids.
