Quantitative Analysis of Bilobalide and Ginkgolides from Ginkgo biloba Leaves and Ginkgo Products Using H-NMR
than 2000 years, making it one of the oldest known medicinal plants. It is of great interest because its leaves possess pharmacological properties that include radical scavenging, improved blood flow, vasoprotection, and anti-PAF (platelet aggregating factor) activity. In numerous experimental models, a ginkgo extract was found to affect vascular and metabolic disturbances as well as neurologic...
متن کاملHigh-performance liquid chromatographic determination of selected flavonols in Ginkgo biloba solid oral dosage forms.
PURPOSE This paper describes a validated high-performance liquid chromatographic (HPLC) - photodiode array (PDA) detection method to quantitate five flavonol components as markers; rutin, quercitrin, quercetin, kaempferol and isorhamnetin for use in the quality control of Ginkgo biloba dosage forms. METHODS Separation was achieved using a minibore Phenomenex Luna 5microm C(18) (2) column with...
متن کاملChemical analysis of Ginkgo biloba leaves and extracts.
The chemical analysis and quality control of Ginkgo leaves and extracts is reviewed. Important constituents present in the medicinally used leaves are the terpene trilactones, i.e., ginkgolides A, B, C, J and bilobalide, many flavonol glycosides, biflavones, proanthocyanidins, alkylphenols, simple phenolic acids, 6-hydroxykynurenic acid, 4-O-methylpyridoxine and polyprenols. In the commercially...
متن کاملAlkylresorcinols in fruit pulp and leaves of Ginkgo biloba L.
These studies were undertaken to characterise resorcinolic lipids (5-n-alk(en)ylresorcinols) composition and to determine their seasonal fluctuations in fruit pulp and leaves of Ginkgo biloba L. Resorcinolic lipid concentrations were consistently higher in fruit pulp than in leaves. In pulp, several mono- and di-unsaturated homologs of alkylresorcinols were the predominant group of analysed lip...
متن کاملEfficient extraction of ginkgolides and bilobalide from Ginkgo biloba leaves.
An efficient and rapid protocol has been developed for extracting ginkgolides and bilobalide (terpene trilactones) from Ginkgo biloba leaves. The procedure takes advantage of the extraordinary stability of the terpene trilactone structure to a variety of chemical treatments, especially oxidation, despite the presence of multiple oxygen functions. The protocol involves boiling the aqueous extrac...
