    Flavanoids and triterpenoids from Cassine papillosa and the absolute configuration of 11,11-dimethyl-1,3,8,10-tetra-hydroxy-9-methoxypeltogynan
    摘要:
    From the stem bark of Cassine papillosa (+)-6R,13R-11,11-dimethyl-1,3,8,10-tetrahydroxy-9-methoxy-peltogynan and (-)-4'-O-methoxyepigallocatechin were obtained and their biogenetic relationship established. They were accompanied by ouratea proanthocyanidin, galactitol, tingenone, tingenin B, and three pentacyclic triterpenes, canophyllol, 3-hydroxylupeol and 30-hydroxylup 20(29)-en-3-one.

  • A trimeric propelargonidin from stem bark of Heisteria pallida
    作者:Verena Dirsch、András Neszmélyi、Hildebert Wagner
    DOI:10.1016/s0031-9422(00)90822-7
    日期:1993.8
    Besides the known ourateacatechin [4'-O-methyl-(-)-epigallocatechin] and ouratea-proanthocyanidin A [epiafzelechin-(4beta-->8)-4'-O-methyl-(-)-epigallocatechin], a new trimeric proanthocyanidin, epiafzelechin-(4beta-->8)-epiafzelechin-(4beta-->8)-4'-O-methyl-(-)-epigallocatechin (trimeric propelargonidin) was isolated from the stem bark of Heisteria pallida. The structure was elucidated by a combination of partial and complete acid hydrolysis, acid-catalysed degradation with toluene-alpha-thiol, FAB-mass spectrometry and C-13 NMR spectroscopy.
  • COMPOSITIONS CONTAINING FLAVANOID POLYPHENOL DERIVATIVES, AND APPLICATIONS THEREOF IN CONTROLLING DISEASES AND AGEING OF LIVING ORGANISMS

    The invention relates to compositions of polyphenol derivatives, characterised in that said polyphenols contain monomers, oligomers or polymers of units of the formula (I), wherein said units are characterised by the simultaneous presence of a phloroglucinol-type core (core A) and of a catechol-type core (core B) bonded together by a segment of 3 carbons such as C, said derivatives being over-activated in terms of nucleophilic power by the alkylation of at least one phenol function of each constituent monomer unit, and stabilised by the esterification of all the others with mixtures of fatty acids in proportions representing those of vegetable oils mainly consisting of AGI. These compositions can particularly be used in cosmetics, nutrition and therapy.

    L'invention a pour objet des compositions de dérivés de polyphénols, caractérisées en ce que lesdits polyphénols renferment des monomères, des oligomères ou des polymères d'unités répondant à la formule (I) : ces unités étant caractérisées par la présence simultanée d'un noyau de type phloroglucinol (noyau A) et d'un noyau de type catéchol (noyau B), reliés entre eux par un segment à 3 carbones tel que C, lesdits dérivés étant suractivés, en ce qui concerne leur pouvoir nucléophile, par alkylation d'au moins une fonction phénolique de chaque unité monomérique constitutive et stabilisés par estérification par des mélanges d'acides gras en proportions reflétant celles d'huiles végétales majoritairement constituées d'AGI, de toutes les autres. Application desdites compositions notamment en cosmétique, diététique et thérapeutique.
