Determination of flavonol glycosides in the leaf of Glucosidos flavonoides biloba L. Chromatographic profiles and identification of new phenolic components of Ginkgo biloba leaves and selected products.

glucosidos flavonoides J Agric Food Chem Aug 13;56 Flavonoids glucosidos flavonoides plants used for the treatment of various cardiovascular, cancer diseases have been reported to possess potential protective effects against oxidative injury.

Ginkgo biloba leaves, known for their antioxidant activity, were chosen for this study.

In this paper, 12 flavonoids in G. HPLC-DAD coupled with chemiluminescence detection was used to determine free radical scavenging activity of glucosidos flavonoides. It was found that the flavonol glycosides could markedly inhibit the luminescent signal, which indicated that they are mainly responsible for glucosidos flavonoides antioxidant activities of G.

Total antioxidant activity of these flavonoids was used to evaluate the differences of G. The combination of chemical and activity analysis can provide a valid glucosidos flavonoides to quantify the bioactive components in G. Quality control of flavonoids in Ginkgo biloba leaves by high-performance liquid chromatography with glucosidos flavonoides array detection and on-line radical scavenging activity detection.


Glucosidos flavonoides Chromatogr A Mar 13; The review is an update of a similar, earlier glucosidos flavonoides in this journal [T.

A ]. Since over papers on Ginkgo biloba have appeared, and about of them pertain to chemical analysis in a broad sense and are cited herein.

The more important ones are discussed and, where relevant, compared with the best methods published prior to In the same period over patents were filed on Ginkgo and the very few related to analysis are mentioned glucosidos flavonoides well. Important constituents include terpene trilactones, i.

Ginkgolide A, B, C, J and bilobalide, flavonol glycosides, biflavones, proanthocyanidins, alkylphenols, simple phenolic acids, 6-hydroxykynurenic acid, glucosidos flavonoides and polyprenols.

In the most common so-called standardised Ginkgo extracts and phytopharmaceuticals several of these classes are no longer present.
