摘要:Acid Hydrolysis Mechanisms Of Orientin-2 ''-O-Galactopyranoside (Oga),Orientin And Other Flavone C-Glycosides In The Trollflowers (Trollius Chinensis Bunge) Were Studied In This Report For The First Time. Hydrolysis Parameters Including Temperature,Acidity,Solvent And Reaction Time Were Comprehensively Investigated. Oga Could Be Hydrolyzed To Orientin,Followed By An Isomerization To Isoorientin Via A Reversible Wessely-Moser Rearrangement Reaction Under Stronger Acidic Conditions. A First-Order Kinetic Model Fitted The Hydrolysis Process Of Oga Well. Under The Optimal Hydrolysis Conditions Of 80 Degrees C,1.0 Mol/l H+ And 7 H Reaction Time,About 77% Oga Was Transformed To Orientin With No Detectable Isoorientin. These Results Could Be Helpful For Better Understanding Of The Acid Hydrolysis Kinetics Of Flavone C-Glycosides,As Well As The Preparation Of These Valuable Components Under Controlled Acid Hydrolysis Conditions.

摘要:The present invention explored PLGA NPs synthesis using plant extracts as surfactants by nanoprecipitation process. PLGA NPs synthesized using Camellia sinensis, Dendrocalamus hamiltonii, Ficus palmata and Rubus ellipticus leaf extracts were further explored for encapsulation, controlled and sustained release of well-known antioxidant molecule, curcumin. This plant extract based nanoprecipitation process for the synthesis of PLGA NPs can be further explored for encapsulation of many other antioxidant molecules of therapeutic importance.

权利人:COGNIS FRANCE SA
摘要:Disclosed is a method for enzymatic synthesis of esters of flavonoid and flavonoid derivatives, according to which a reaction medium containing an organic solvent, a glycosylated flavonoid or aglycon flavonoid, an acyl group donor, and an enzymatic catalyst is produced, b) additional quantities of flavonoid and/or acyl donor are optionally added during the reaction, and c) the obtained esters are separated from the enzymatic particles and the solvent. The inventive method is characterized by maintaining the concentration of water and/or alcohol which are formed during the reaction to below 150 mM. Advantageously, the molar ratio of flavonoid to acyl donor in the reaction medium is maintained in the range from 0.01 to 20.00 during the reaction.

摘要:The present invention discloses the composition of antioxidant of bamboo leaves (AOB) and its use. The purpose of present invention is to provide a new food additive which is natural, nutritional, and muti-functional, and which is of rich resources, safety, good effect, and low cost. AOB is yellow or brown powders or particles obtained from bamboo leaves, wherein the main antioxidative components include flavones, lactones, phenolic acids. AOB can either inhibit lipid autoxidation chain reaction, or chelate transitional metal ions, and can be used as primary and second antioxidant. AOB can eliminate nitrite and inhibit the synthesis of N-nitrosamine, and has anti-bacteria, bacteriostatic, deodorizing, aroma enhancing etc. functions. AOB can be commonly used in oil-containing food, meat product, fishery product, expanded food etc. food systems.

标 题:Reversing baldness through cannabinoid receptor activation
发明人：POSTREL RICHARD
权利人:POSTREL RICHARD
摘要:This invention reverses male pattern baldness by shocking dormant hair follicles out of their androgen induced hibernation phase back to the active hair-growing anagenic phase. The invention integrates two functions: 1) It blocks synthesis of compounds holding the follicles in the telogenic/hibernating phase and 2) It stimulates synthesis of compounds animating the hair-growing/anagenic phase in the follicular activity cycle. One preferred embodiment comprises an enzyme inhibitor blocking the conversion of testosterone to dihydrotestosterone (DHT), a flavonoid simultaneously increasing synthesis of prostaglandins alternative to prostaglandin D2, and a selected cannabinoid compound stimulating restore the hair follicle to its normal growth cycle. This novel trimodal therapy restores the hair follicles to their normal cycling processes and maintains these restorative properties so long as this rebalance in maintained.
