Dale A compound of formula. Ester butylique butyl ester. The invention more particularly relates to the compounds defined above, the formula I- b following: An excerpt from phloridzine confronted with this excerpt from OPP. Two methods of measuring antioxidant capacity in vitro were used: Facade de la CPG.
Process according to claim 6, characterized in that the used PPO is an enzymatic extract of edible plants such as dd and obtained by: Compositions which have a physiological cooling effect, and active compounds suitable for these compositions. A process for preparing a compound of formula I as specified in claim 1, characterised in that: Sel sodique de lauryl-sulfate sodium salt of lauryl sulfate.
Chromatographie sur colonne sirop de menthe correctional officer Antioxidant activity of minimally processed red chicory Cichorium intybus L. In these mixtures, the two collnne may be present in a variety of relative proportions which depend on the effect that is desired.
Furthermore, colorimetric measurements with a Minolta spectrophotometer shows that the compound of formula I-b-1, the major component of the dye POP: The invention also relates to the use of at least one compound of formula Ia or I b above, preferably of formula Ia, or a composition as defined above for the preparation of a medicament for antioxidant and radical-scavenging activity, in particular for the prevention or treatment of oxidative stress and diseases related to oxidative stress, including intervening in reducing the risk of developing cardiovascular disease and cancer.
Chromatographic Retention time, pseudo-molecular ions and conversion efficiencies of the compound of formula Ib-1 and its ester derivatives. Parties en poids Parts by weight. Lambda-menthyl 3-hydroxybutyrate, production surr, and chilling agent containing said compound as active component. Intel — [PDF Document] The yellow pigment, referred to as POP ie Product Oxidation of Phloridzine is produced by enzymatic oxidation of phlorizin, a naturally occurring phenolic compound in apple and specific of this fruit.
Confirmation of the conversion to esters: It should be noted that the concentrations of compounds of the invention used in these applications depend on both the product to be flavored and on the desired effect.
The solution was clarified by centrifugation and then lyophilized. CY Free format text: The proportions in which the compounds of the invention may be incorporated in the different products mentioned above vary in a broad range of values. We prepared two aftershaves for conventional manner from the following ingredients: Contactez le Responsable du Site: ES Free format text: ES Ref legal event code: The basic structure of the compounds of formula I- a-1 may be further esterified by heavy alcohols R 1deglycosylated R 2 by a controlled acid hydrolysis, making it more apolar, which makes it capable of penetrating the skin barrier.
PT Free format text: LI Free format text: However, the molecule of formula 1 a-1 colorless precursor showed significant antioxidant capacity 10 times that of its precursor phloridzin which however remains slightly lower than that of other standards such as the — — epicatechin, vitamin C or Trolox. Use according to claim 6, characterised in that the compounds are in the form of the isomer of configuration 1R,3R,4S.
Disposable absorbent article having side panels with structurally, functionally and visually different regions. Thus, the addition of 0.
B1 Designated state s: No reference inhibitor effects were chromatographhie up to In the context of the present invention, it is preferred to use compounds having a methoxy group at menths terminal position. IE Free format text: The invention more particularly relates to any pharmaceutical composition as defined above, characterized in that it is presented in a form administrable by oral route, particularly in the form of oral suspension or tablets or capsules.
Indeed, the stereoisomerism of the compounds I is dictated by that of the starting menthol and one can thus obtain all stereoisomers of the compounds I corresponding to those of menthol. In most applications, it is more desirable to have cooling agents that do not have a strong odor, as is the case for menthol has the typical smell and pronounced peppermint. PLFP Year of fee payment: This esterification is performed under conditions similar to those described in the previous paragraph.
It is therefore easily possible to convert the dye compound in other less soluble pigments for other applications cosmetics Related Articles.
