Ginkgo biloba flavonoids are one of the most popular herbal supplements, taken for their perceived “memory enhancing” properties. In this paper, the current studies of Ginkgo biloba flavonoids from leaves is been reviewed. Flavonoids are derived from the products of the shikimate and acetate-malonate pathways. Flavonoid concentration in G. biloba leaves is not only regulated by the involvement of genes, but also by other factors, such as photosynthesis, tree age, season, extent of leaf maturity…

The tree is slow growing, adapted to many ecological conditions and shows numerous adaptation in developmental patterns, especially the various parts of the tree that are used in orthodox or traditional medicine to treat diseases due to the many bioactive compounds.

Seasonal Pattern of Flavonoid Content and Related Enzyme Activities in Leaves of Ginkgo biloba L.

A significant correlation between CHS activity and the flavonoids content showed that CHS was one of the key enzymes involved in flavonoid biosynthesis.

Effect of Methyl Jasmonate on the Terpene Trilactones, Flavonoids, and Phenolic Acids in Ginkgo biloba L. Leaves: Relevance to Leaf Senescence

In general, JA-Me application affected leaf senescence by modifying the accumulation of ginkogolides, flavonoids, and phenolic acids, and these effects were also found to be different in leaf blades and petioles.

Variation of terpene lactones composition in Ginkgo biloba (L.) leaves under the influence of harvesting time and growing location

A tendency was found that the amount of terpene lactones in Ginkgo biloba leaf samples decrease with the increasing age of the plant, and to ensure the optimal collection of raw material, it is recommended to place the G. biloba plantations in northern and western regions to collect the highest amount of ginkgolide A, B, C and bilobalide.

Synthesis of Phenolics and Flavonoids in Ginger (Zingiber officinale Roscoe) and Their Effects on Photosynthesis Rate

Ginger is a semi-shade loving plant that does not require high light intensity for photosynthesis, and different photosynthesis rates at different light intensities may be related to the absence or presence of some flavonoid and phenolic compounds.

Effect of salicylic acid application on biochemical changes in ginger (Zingiber officinale Roscoe)

Salicylic acid (SA) belonging to plant phenolics group is found in some plant species and is capable of enhancing plant growth and yield. Effects of SA application (10−3 and 10−5 M) on synthesis of



Study on the relationship between the flavonoids and pigments in Ginkgo biloba leaf

The concentrations of chlorophyll, anthocyanin and flavonoid in Ginkgo biloba leaf were assayed in 1999. The results indicate that there are two peaks of flavonoid content, one on July 4 and the

Study on the synthesis and metabolism of the flavonoids in Ginkgo biloba leaf

The flavonoids, anthocyanin, simple phenols, lignin and soluble protein of the leaves in Ginkgo biloba phylomes were assayed in 1998--1999. The results indicated that there were two peaks of

Chemical analysis of Ginkgo biloba leaves and extracts.

Studies on molecular mechanisms of Ginkgo biloba extract

Claims that standardized G. biloba extract (EGb 761) can modulate the cellular environment of an organism under both physiological and stress conditions may be attributed to its multivalent or totipotent properties, and can now be substantiated by the availability of modern molecular techniques.

Overexpression of petunia chalcone isomerase in tomato results in fruit containing increased levels of flavonols

Processing of high-flavonol tomatoes demonstrated that 65% of flavonols present in the fresh fruit were retained in the processed paste, supporting their potential as raw materials for tomato-based functional food products, and upregulated flavonol biosynthesis in the tomato in order to generate fruit with increased antioxidant capacity and a wider range of potential health benefit properties.
