În baza efectelor reacţiilor analitice, a fost determinată prezenţa alcaloizilor cu ajutorul reactivilor generali de precipitare: Bouchardat, tanin, fosforovolframic, fosforomolibdenic, picric; taninurilor cu: alaun de fier şi amoniu, acid acetic 10%, acetat de plumb 10%, iar flavonoidelor cu acetat bazic de plumb şi proba cianidinică.

Based on the analytical reactions, the alkaloid presence has been determined through the general precipitation reactives: Bouchardat, tannin, phosphowolpharmic, phosphomolybdic, picric; the tannins presence with: iron and ammonium alloys, 10% acetic acid, 10% lead acetate and the flavonoids presence with basic lead acetate and cyanohydrin reaction.
