Effects of the leaf extract Ginkgo biloba, ginkgolides A and B, and the amino acid taurine (2-aminoethane sulfonic acid) on platelet aggregation was studied. All potential anitcoagulants were incubated in day one platelet-rich plasma and subjected to various agonist-induced clotting and tests and other measures of platelet viability. G. biloba extract and its respective ginkgolides had no effec...

Autumnal tints are one of the most fascinating natural phenomena, but the molecular mechanism of chlorophyll (Chl-)degradation in deciduous trees has not been fully understood. In this study, from the leaves of Ginkgo biloba, chlorophyllase-homologous GbCLH was cloned by RT-PCR with degenerated primers. The expression of GbCLH in different yellowing stages was analyzed by Northern hybridization...

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...

Total phenolic content and antioxidant capacity (FRAP method) of Ginkgo biloba L. leaves collected from male and female trees were determined and compared. Different water and aqueous ethanolic (water/ethanol 80/20, V/V) extracts were prepared by varying the time of infusing, boiling and steeping in order to determine the effect of the extraction method on the above parameters. Antioxidant acti...

background: multiple sclerosis (ms) is a chronic demyelinating disease that can affect cognitive function. the purpose of this study was to assess the efficacy of ginkgo biloba (gb) on improvement of memory impairment and quality of life in patients with ms. methods: this study was an 8-week, open study of patients with ms. thirty patients was recruited from a variety of outpatient settings. al...

Cytotoxic activity profiling of the n-hexane extract from fruit pulp Ginkgo biloba L. (Gingkgoaceae) led to purification 8 compounds. HPLC based identified a cytotoxic alkenylresorcinol. The was further separated by time-based fractionation in gradient condition, and cytotoxicity each fraction evaluated using 293, B16F10, BJAB, HCT116 cancer cells vitro. Bilobol isolated as an active constituen...

The study described in this paper aims to compare the efficacies of homeopathy and allopathic therapy for tinnitus of different etiologies and periods of time since onset. It is a retrospective study with a lower reliability than prospective ones, but reaching the same results regarding the Gingko Biloba therapy as the most prospective studies published, respectively its efficacy only in vascul...

Cannabis sativa preparations are the most commonly used illicit drugs worldwide. The present study aimed to investigate the effect of Cannabis sativa extract in the working memory version of the Morris water maze (MWM; Morris, 1984[43]) test and determine the effect of standard memory enhancing drugs. Cannabis sativa was given at doses of 5, 10 or 20 mg/kg (expressed as Δ(9)-tetrahydrocannabino...
