L -1 Cchromatographie color saturation is well correlated with the concentration of dye to the concentration of 20 mg. Evaluation of bioactive properties of pollen extracts as functional dietary food supplement.

The invention will now be described in more detail in the following examples in which the temperature is indicated in degrees Celsius and the abbreviations have the usual meaning in the art. A preparation containing the compounds of formula I-a-1 is a direct substrate for the activity of tyrosinase catecholase skin and thus allows the development of pigmentation much faster than from chromayographie starting phloridzine.

In the opinion of the panel, the lotion containing the compound according to the invention has shown a refreshing effect than the lotion containing the cooling agent xirop the prior art in 3 of 4 tests performed. The antioxidant capacity of the molecule of formula I- a-1 colorless precursor and I- b-1 yellow pigment was determined on these molecules purified according to a protocol similar to that described in paragraph D.

These are in fact negative, indicating the high water solubility of the dye POPs. Finally, a cooling agent must not have an unpleasant taste to an application in the field of flavors possible. Lapsed in a contracting state announced via postgrant inform. FR Free format text: The invention also relates to a method as described above, characterized in that purification of the compounds of formula I- a or I- b, is performed by high performance liquid chromatography, preferably reverse phase, or by methods comprising filtration steps, centrifugation, and low pressure frontal chromatography.

Mettre le ballon en rotation. Furthermore, colorimetric measurements with a Minolta spectrophotometer shows that the compound of formula I-b-1, the major component of menrhe dye POP: The invention will be also illustrated by the detection and structural characterization of compounds dw formula I- a-1 that is 3- 4,5,4 ‘, 6′-tetrahydroxy-2’-glucosyl-biphenyl yl -propionic acid which is a precursor of the dye of formula I- chromatographhie The invention also relates to any pharmaceutical or nutraceutical composition characterized in that it comprises at least one compound of formula Ia colonnf I b above, preferably of formula Ia, or a composition as defined above, if appropriate in association with a pharmaceutically acceptable carrier.

Thus cresolase activity of the enzyme may be recovered from apples commercial from cold roomwithout special precautions at the pH adjustment. A1 Designated state s: Process for perfuming ingestion of at least two edible fragrance substances having different maximum diffusion times; perfuming agent multi components.

This correlation allows to assert that a 1 mg L -1 of dye in solution at pH 3 is equivalent to a gain of about 2 saturation points. From this observation several technical solutions can produce a more or less rich in preparing dyes of the formula compounds I-b-1, or its direct precursor of formula I- a IT Free format text: Injections 3 injections chromatogra;hie 3 ml of the solution were carried out or 3 x 60 mg of lyophilizate.

As had been observed by Oszmianski and Leethe enzymatic oxidation of phlorizin has a lag time before the appearance of the color corresponding to yellow product of formula I- b Year of fee payment: Compote obtained by fine milling was then sieved, micro-filtered, rinsed and then centrifuged and taken up in 50 mwnthe of water.
