The seeds of Ginkgo biloba are commonly eaten in Japan, Korea and China, but it is important to know that they can be responsible for poisoning, especially in young children. Poisoning due to Ginkgo biloba seeds must also be considered as a possible clinical event in European countries, where Asian cuisine has recently become popular. This paper reports the case of a 23-months-old previously he...

BACKGROUND Ginkgo biloba L. (Ginkgoaceae) leaf extract is one of the most popular herbal products on the market, as it contains flavone glycosides (≥ 24%) and terpene lactones (≥ 6%), which are proposed to have significant physiological effects. Unfortunately, the challenging financial climate has resulted in a natural health product market containing adulterated ginkgo products. PURPOSE 42 g...

BACKGROUND European Regulation 1924/2006 states that all health claims made on foods need to be substantiated scientifically. OBJECTIVE To apply the PASSCLAIM criteria for the scientific substantiation of health claims on foods to herbal supplements containing Ginkgo biloba. Evaluation of three selected claimed health effects for G. biloba (improvement of blood circulation, improvement of sym...

Ginkgo biloba, a dioecious plant known as a living fossil, is an ancient gymnosperm that stands distinct from other gymnosperms and angiosperms. Ginkgo biloba var. epiphylla (G. biloba var. epiphylla), with ovules borne on the leaf blade, is an unusual germplasm derived from G. biloba. MicroRNAs (miRNAs) are post-transcriptional gene regulators that play critical roles in diverse biological and...

The final size of plant leaves is strictly controlled by environmental and genetic factors, which coordinate cell expansion cycle activity in space time; however, the regulatory mechanisms leaf growth are still poorly understood. Ginkgo biloba a dioecious species native to China with medicinally phylogenetically important characteristics, its fan-shaped unique gymnosperms, while mechanism G. de...

The risk of interaction between dietary supplements, herbal drugs and synthetic drugs increases when patients are treated chronically, e.g. due to impairment of central nervous system (CNS)--depression, psychotic disorders, Parkinson's and Alzheimer's diseases. On the basis of scientific literature, there was shown that simultaneous intake of antidepressants, antipsychotic drugs and herbal drug...

A rapid microwave-assisted hydrolysis (MAH) method is presented for the sample pretreatment of the determination of ginkgo flavonol glycosides in extracts of Ginkgo biloba L. (EGb). By this method, flavonol glycosides can be completely hydrolyzed within 2 min. After investigating the effects of solvents, acidity, microwave power, and microwave radiation time on hydrolysis, the optimal hydrolysi...
