The invention relates to the use of chromen-4-one derivatives of the formula I 

Use of chromen-4-one derivatives

The invention relates to specific benzodioxepin-3-one compounds, to a process for the preparation thereof and to the use thereof as dyes or as fluorescent emitters for organic electroluminescent devices (OLEDs) or for organic light-emitting electrochemical cells (OLECs), and to corresponding electronic devices.

Benzodioxepin-3-one compounds as dyes or as fluorescent emitters

The invention relates to complexes of certain flavonoid derivatives, of the formula I compositions which comprise such derivatives, corresponding processes for the preparation of the flavonoid derivatives or of compositions comprising same, and the use thereof, in particular for the care, preservation or improvement of the general state of the skin or hair. Formula (1), in which Zto Zand Zto Zeach, independently of one another, denote H, OH, CHCOO, alkoxy, hydroxyalkoxy, mono- or oligoglycoside radicals and where the alkoxy and hydroxyalkoxy groups may be branched and unbranched and can have 1 to 18 C atoms. Formula (II) denotes, Zis a mono- or the oligoglycoside radical, where bonded to this glycoside radical, in each case via an &#x2014;O&#x2014; group, is at least one radical selected from certain benzo molecule. 

Flavonoid complexes with cyclodextrins

The present invention relates to the use of self-tanning substances for application to the human skin, with application taking place at elevated temperature, to corresponding methods of application to the human skin and to a cosmetic formulation which is suitable for said purpose.

Method of tanning human body by mysting or immersion at elevated temperature

The invention relates to compounds of the formula I where R, R, R, Rand Rhave the meanings given in claim 1. The compound is suitable in particular for use in skin care compositions. They protect, firstly, against harmful oxidation reactions and, secondly, also act as UV filters.

Galenical formulation

The invention relates to a cosmetic or pharmaceutical formulation comprising at least one compound of formula (I). The cosmetics or pharmaceutical products are particularly suitable for the care of the skin in protecting against oxidative stress and ageing phenomena.

Formulation comprising benzofuranone derivatives for protection against oxidative stress

The invention relates to a method for recovering high-purity isoquerectin from bioflavonoid pastes, that is from mother-liquor residues which are produced during the recovery of flavonoids, by extraction with a solvent mixture of methyl acetate and water.

Recovery of isoquercetin from bioflavanoid pastes

The invention relates to a conjugate which can be used for preparing dermatological and cosmetic compositions. The invention also relates to processes for preparing such conjugate and to its use.

Conjugate, its preparation and use

Disclosed is a method for producing compounds of formula (I), wherein R represents H or (CH ) OH, R represents H or (CH ) OH, R represents H or (CH ) OH and m, n and p represent 2-8 independently from one another. Said compounds are particularly suitable for use as food supplements. They are highly suitable for use in cosmetic formulations as UV filters, for instance.

Method for producing luteolin and luteolin derivatives
