A recently developed revolutionary approach to transcriptomics, RNA-Seq, and suppression subtractive hybridization are powerful tools for gene expression research. However, currently, the difficulty of isolating high-quality RNAs from plant tissues bearing abundant complex polysaccharides, polyphenolics, and secondary metabolites is a serious problem that not only limits the application of thes...

For good bioavailability, natural products must have a good balance between hydrophilicity (for dissolving into the gastro-intestinal fluids) and lipophilicity (to cross lipidic biomembranes). Many phytoconstituents like glycosilated polyphenolics have good water solubility, but are, nevertheless, poorly absorbed[1] because of their large size, incompatible with a process of passive diffusion a...

Plant-based antioxidants such as polyphenols have gained significance in primary health care needs, due to their potential and therapeutic use modern medicine. Thus, the present study aimed evaluate, for first time, effect of solvents on extraction yield, polyphenolics, phytoconstituents antioxidant properties various extracts (aqueous, methanol, ethyl acetate, dichloromethane, hexane) Echium h...

Blueberries are commonly consumed in processed forms, but limited information is available on how different processing methods and storage of processed products impact the polyphenolic content of the fruit. In this study, we determined how canning, puréeing and juicing of blueberries, as well as storage of processed products at 25°C, influenced the retention of chlorogenic acid, total flavonols...

Rhizoma A. officinarum (Hance) Farw, synonymously is called rhizoma galangae or smaller galangal (hereafter abbreviated as AO). Numerous studies reported that AO possesses anti-inflammatory, anticancer, chemoprotective, antibacterial, antifungal and diuretic properties. To understand whether AO exhibits antihyperlipidemic bioactivity and what is the mechanism of action, we performed chemical an...

Native American Pomo communities who live in the Northern Coastal range of California and consume acorns from tanoak trees as part of traditional diets are facing the potential loss of many culturally important trees to sudden oak death. Pomo and other Native American communities are reluctant to use the protective fungicide, potassium phosphonate, on trees used for acorn collection without inf...

Clingstone peaches contain a wide array of complex secondary plant metabolites and polyphenolics, and increasing evidence indicates that many of these components are important in human health. Oligomeric flavan-3-ol metabolites (procyanidins) are particularly interesting owing to their potent antioxidant activity and protective cardiovascular effects. To date, little information is available on...
