Abstract
Canadian golden rod (Solidago x Canadensis L., Asteraceae) has been used in European phytotheraphy for 700 years as a urological and antiphlogistical remedy.
Dissolution rates of quercetin glycosides and organic acids have been studied, as well as mineral elements of Solidaginis herba into different tinctures and aqueous extracts.
Determination of the flavonoids in Solidaginis herba (16.75 mg/g) and of flavonoid release in extracts (14.9-72.9 %) was carried out by spectrophotometric analysis.
To study the flavonoid composition of the crude drug, an HPLC technique was applied.
The concentrations of 16 mineral elements (Al, B, Ba, Ca, Co, Cr, Cu, Fe, K, Mg, Mn, Na, P, S, Ti, Zn) in the samples were measured by inductively coupled plasma atomic emission spectrometry (ICP-OES). Connection has been found between some ion concentrations and the presence and quantity of flavonoids.
