The aim of the present study was to examine the apoptotic effect of flavonoids in methanol extracts of Ginkgo biloba fallen leaves (MEGFL) on melanoma cells. Ginkgo biloba is a deciduous castle chaplain and its leaves include various types of flavonoids such as flavonol-O-glycosides. Ginkgo biloba is known to have therapeutic properties against a number of diseases such as cerebrovascular disea...

OBJECTIVE The purpose of this study was to evaluate, by using distortion product otoacoustic emission test, the action of Ginkgo biloba extract 761, which has a known antioxidant property, as a possible otoprotective against cisplatin induced hearing loss. This prospective and double blinded study was conducted on individuals that were to begin cisplatin treatment in a tertiary university cente...

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...

BACKGROUND Cardiovascular disease (CVD) was a preplanned secondary outcome of the Ginkgo Evaluation of Memory Study. The trial previously reported that Ginkgo biloba had no effect on the primary outcome, incident dementia. METHODS AND RESULTS The double-blind trial randomly assigned 3069 participants over 75 years of age to 120 mg of G biloba EGb 761 twice daily or placebo. Mean follow-up was...

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...

BACKGROUND The benefit of Ginkgo biloba has been discussed controversially. The aim of this review was to assess the effects of Ginkgo biloba in Alzheimer's disease as well as vascular and mixed dementia covering a variety of outcome domains. METHODS We searched MEDLINE, EMBASE, the Cochrane databases, CINAHL and PsycINFO for controlled trials of ginkgo for Alzheimer's, vascular or mixed deme...

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...

We report on a patient with glucose-6-phosphate dehydrogenase (G6PD) deficiency who developed acute hemolytic anemia after having received an injection of Ginkgo biloba for dementia prophylaxis without medical advice. She suddenly developed general malaise, generalized yellowish skin color, and tea-colored urine. Intravenous fluid infusion and cessation of G. biloba quickly relieved her clinica...

Objective(s): In this work, Ginkgo biloba extract (GBE) loaded solid lipid nanoparticles (SLNs) were synthesized via high pressure homogenization method and their physicochemical properties, as well as cytotoxicity and antibacterial activities were evaluated.Methods: Ginkgo biloba extract SLNs (GBE-SLNs) were prepared using high pressure homogenization method. The morphology and size of S...

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...
