Maidenhair tree (Ginkgo Bilobae) leaf extraction products in the light of Biopharmaceutics Classification System (BCS) requirements and medium of diversified polarity (εM)
Journal Title: Herba Polonica - Year 2014, Vol 60, Issue 1
Abstract
Model maidenhair tree (Ginkgo bilobae) leaf extracts were created basing on medium of diversified polarity (ԐM). Chromatographic analysis was performed with the HPLC method, with the so-called dry residue remaining after evaporating the dissolving agent from saturated aqueous solutions and from 0.1 mol HCl. Viscosity measure and surface activity estimations were conducted on phase boundary. Then, basic values of viscosity ([h], Mh ) and hydrodynamic values (Ro, Robs., Ω) were calculated. Moreover, reference quercetin and rutin (rutoside) were used to mark the conversion contents of flavonoids in produced extracts with the UV method.
