Determinarea alcaloizilor totali din Atropa belladonna si Lupinus sp.prin diferite metode spectrofotometrice si gravimetrice

摘要

Extracting and dosing total alkaloids from Atropa belladonna and Lupinus sp.is critical due to their physiological effect on neurological and muscle system.In the case of Atropa belladonna,quantifying tropanic alkaloids is done using a colorimetric method based on Vitali-Marin reaction,first described by Alpert and Wilson.Nephelometric and gravimetric methods have been used for alkaloids from Lupinus sp.Those methods are based on complex combinations between chino-lizidine alkaloids and silico-wolframie acid creating structures like SiO_212WO_3 alkaloid 2H_2O.
