BACKGROUND Ginkgo biloba L. (Ginkgoaceae) is one of the most distinctive plants. It possesses a suite of fascinating characteristics including a large genome, outstanding resistance/tolerance to abiotic and biotic stresses, and dioecious reproduction, making it an ideal model species for biological studies. However, the lack of a high-quality genome sequence has been an impediment to our unders...
Environmental pollution is an important issue in metropolitan areas, and roadside trees are directly affected by various sources of to which they exhibit numerous responses. The aim the present study was identify morpho-physio-biochemical attributes maidenhair tree (Ginkgo biloba L.) American sycamore (Platanus occidentalis growing under two different air quality conditions (roadside with high ...
Commercially available medicinal plant extracts such as Ginkgo biloba leaf extract show no consistent pattern of clinical benefit for people with dementia or cognitive impairment, and have been suggested to be toxic to cells at higher doses. However, medicinal plants may contain other more efficient bioactive molecules apart from the well-known flavonoids and terpenoids. Recombinant therapeutic...
The case of a 56 year old man who suVered a spontaneous intracerebral haemorrhage after regular self medication with the herbal preparation, Ginkgo biloba leaf extract is described, and the possible association is discussed. (Postgrad Med J 2001;77:112–113)
Ginkgo biloba (EGb 761) as a phytotherapeutic agent used in otoneurology, psychiatry, and ophthalmology. We studied the efficacy of therapy with EGb 761 in 72 patients (44 male and 28 female) with chronic cochleovestibular disorders. We used pure-tone audiology, measuring pure-tone average, speech reception threshold, and speech discrimination score. Then we used craniocorpography to measure la...
By Sephadex LH-20 gel chromatography of an extract from Gingko biloba leaves, polymeric proanthocyanidins were eluted after the fractions of flavonol glycosides and biflavone glycosides. A purified proanthocyanidin polymer accounted for 86.6% of the total proanthocyanidins, and for 37.7% of the total antioxidant activity of this leaf extract. For structure elucidation, the polymer was submitted...
The antibacterial activity of methanol, ethanol, chloroform, and hexane extracts of the leaves of Himalayan gymnospermous plant Ginkgo biloba L. was assessed against five animal and plant pathogenic strains (Agrobacterium tumefaciens, Bacillus subtilis, Escherichia coli, Erwinia chrysanthemi, and Xanthomonas phaseoli) employing disc-diffusion and broth-dilution assays. The methanol extract show...
As one of the most ancient tree species, the codon usage pattern analysis of Ginkgo biloba is a useful way to understand its evolutionary and genetic mechanisms. Several studies have been conducted on angiosperms, but seldom on gymnosperms. Based on RNA-Seq data of the G. biloba transcriptome, amount to 17,579 unigenes longer than 300 bp were selected and analyzed from 68,547 candidates. The co...

Autumnal tints are one of the most manifest and fascinating natural phenomena, but the mechanism of chlorophyll (Chl)-breakdown in deciduous trees has not been fully elucidated. In this study, we analyzed the composition of Chl-related compounds and determined the activities of initial Chl-degrading enzymes in Ginkgo leaves at various stages in the process of autumnal coloring. Only pheophytin ...
