Introduction. The standardization of vegetal products plays an important role in ensuring the quality and safety of herbal medicines. Material and methods. European goldenrod Solidago virgaurea and Canadian goldenrod S. canadensis plants, harvested in the flowering phase from the central area of the Republic of Moldova, served as biological material. Determination of some specific tests: Loss on drying, Total ash and Ash insoluble in hydrochloric acid, was carried out according to the European Pharmacopoeia 10th edition (Ph. Eur. 10.0). Results. The following data were obtained for Loss on drying parameter: for vegetal product Solidaginis virgaureae herba – 11.2% (Ph. Eur. – maximum 12.0%), and for vegetal product Solidaginis canadensis herba – 9.6% (Ph. Eur. – maximum 10.0%). The results for Total ash test reveal a value of 4.8% for Solidaginis virgaureae herba (Ph. Eur. – maximum 8.0%), and an ash content of 3.5% for Solidaginis canadensis herba (Ph. Eur. – maximum 7.0%). For the parameter Ash insoluble in hydrochloric acid, the subsequent data were determined: Solidaginis virgaureae herba – 0.8%, Solidaginis canadensis herba – 0.5% (Ph. Eur. – maximum 1.0%). Conclusions. Determination of some standardization parameters for the vegetal products of Solidago species pointed out results that are in full agreement with the requirements described in the Ph. Eur., which represent starting points for the development of the Pharmacopeial Monograph projects for these vegetal products.
