Transcriptomic Signatures of Ash (Fraxinus spp.) Phloem
BACKGROUND Ash (Fraxinus spp.) is a dominant tree species throughout urban and forested landscapes of North America (NA). The rapid invasion of NA by emerald ash borer (Agrilus planipennis), a wood-boring beetle endemic to Eastern Asia, has resulted in the death of millions of ash trees and threatens billions more. Larvae feed primarily on phloem tissue, which girdles and kills the tree. While ...
متن کاملGlucosylated sesquiterpene alcohols from Fraxinus griffithii.
Phytochemical investigation of the leaves of Fraxinus griffithii has led to the isolation of two new glucosylated acyclic sesquiterpene alcohols, griffithosides D (1) and E (2), along with iridoid and secoiridoid glycosides. The molecular structures of these compounds were elucidated using NMR, MS and other spectroscopic techniques, as well as comparison with literature data. The isolated compo...
متن کاملP11: The Effect of Flavonoids in Memory
Flavonoids may exert particularly powerful actions on mammalian cognition and may reverse age-related declines in memory and learning. Flavonoids can be modulated neuronal function and there by influencing memory, learning and cognitive function. Dietary supplementation with flavonoid-rich foods, such as blueberry, green tea and Ginkgo biloba lead to significant reversals of age-related deficit...
متن کاملSterols and Flavonoids of Lomatopodium staurophyllum
Background: The genus Lomatopodium Fisch. & C.A.Mey., belongs to Apiaceae family and contains one herbaceous species growing wildly in Iran. There are only a few papers about the chemical constituents of these plants. Here, we focused on the isolation and identification of the main flavonoid glycosides and sterols from the aerial parts of L. staurophyllum, which has not been previously reported...
متن کاملEnteric disposition and recycling of flavonoids and ginkgo flavonoids.
OBJECTIVE The objective of this study was to determine the intestinal and microbial disposition of flavonoids and how these disposition processes affect their enteric recycling. DESIGN Studies were performed using a perfused rat intestinal model or using enrichment cultures and a pure isolate of Enterococcus avium (LY1). RESULTS In the rat intestine, aglycones, such as quercetin and apigeni...
