\u00c9tude de la composition chimique et de l'activit\u00e9 biologique des produits de fermentation solides du Vanisan Yellow
\nSanghuang est un terme g\u00e9n\u00e9ral d\u00e9signant une vaste cat\u00e9gorie de champignons durs et poreux, nomm\u00e9s d'apr\u00e8s leur croissance sur les troncs de m\u00fbriers et leurs fructifications brun-jaune. En tant que champignon m\u00e9dicinal traditionnel r\u00e9put\u00e9 en Chine, l'utilisation m\u00e9dicinale la plus ancienne de Sanghuang remonte au \"Shennong Bencao Jing\", qui l'appelle \"oreille de Sanghuang\". Il est utilis\u00e9 pour traiter l'effondrement et la diarrh\u00e9e chez les femmes, ainsi que la fi\u00e8vre chez les hommes, et pour traiter la stase sanguine et le sang rouge. En raison de la vari\u00e9t\u00e9 de grandes bact\u00e9ries poreuses de couleur et de duret\u00e9 similaires, il est difficile de les distinguer en apparence, de sorte que la reconnaissance de l'esp\u00e8ce Sanghuang a longtemps fait l'objet d'une grande controverse. Au cours des derni\u00e8res d\u00e9cennies, les chercheurs sont progressivement parvenus \u00e0 un consensus sur la classification de Sanghuangporus, estimant qu'il appartient \u00e0 l'embranchement des Basidiomycota, \u00e0 l'ordre des Agaricomycetes, \u00e0 l'ordre des Hymenochaetales, \u00e0 la famille des Hymenochaetaceae et aux champignons poreux de grande taille. Un nouveau genre, Sanghuangporus, a \u00e9t\u00e9 cr\u00e9\u00e9. \u00c0 l'heure actuelle, il existe 14 vari\u00e9t\u00e9s de champignons Sanghuang dans le genre Sanghuang. Compar\u00e9 \u00e0 d'autres vari\u00e9t\u00e9s, le Vanisan Sanghuang a une teneur plus \u00e9lev\u00e9e en principes actifs, un large \u00e9ventail d'activit\u00e9s biologiques et l'avantage d'une culture artificielle facile, ce qui en fait l'une des vari\u00e9t\u00e9s les plus commercialis\u00e9es.
\nLa recherche moderne montre que le Phellinus igniarius a une vari\u00e9t\u00e9 d'activit\u00e9s biologiques, telles que l'anti-inflammation et l'antioxydation, l'anti-tumorale et la r\u00e9gulation immunitaire, l'antidiab\u00e8te, la protection du foie et la neuroprotection. Il s'agit d'une source potentielle d'aliments fonctionnels et de m\u00e9dicaments th\u00e9rapeutiques. \u00c0 l'heure actuelle, les recherches sur les ingr\u00e9dients actifs du Vanisan Yellow se concentrent principalement sur le corps fructif\u00e8re, et il y a relativement peu de recherches sur la composition chimique des produits de fermentation solides. Par cons\u00e9quent, cette exp\u00e9rience a \u00e9tudi\u00e9 les composants chimiques des produits de fermentation solides du Vanisan Yellow par des m\u00e9thodes de s\u00e9paration syst\u00e9matiques et a \u00e9valu\u00e9 l'activit\u00e9 antioxydante in vitro, la xanthine oxydase et l'activit\u00e9 inhibitrice de l'\u03b1-glucosidase des compos\u00e9s obtenus, fournissant ainsi une base scientifique pour le d\u00e9veloppement ult\u00e9rieur du Vanisan Yellow.<\/p>\n

\nLes polyph\u00e9nols, les terp\u00e8nes, les polysaccharides et d'autres substances pr\u00e9sentes dans les champignons Sanghuang ont de riches activit\u00e9s pharmacologiques et de vastes perspectives d'application. Toutefois, l'analyse de la litt\u00e9rature a r\u00e9v\u00e9l\u00e9 que la recherche sur la composition chimique du Sanghuang se concentre principalement sur le corps fructif\u00e8re, et qu'il existe relativement peu de recherches sur la composition chimique du Sanghuang \u00e0 partir de sources de fermentation. Par cons\u00e9quent, dans cette exp\u00e9rience, 17 compos\u00e9s ont \u00e9t\u00e9 isol\u00e9s \u00e0 partir du produit de fermentation solide du Vanisan Yellow, et leur activit\u00e9 antioxydante in vitro, leur activit\u00e9 inhibitrice de l'\u03b1-glucosidase et leur activit\u00e9 inhibitrice de la xanthine oxydase ont \u00e9t\u00e9 examin\u00e9es. Les compos\u00e9s 1 \u00e0 9 ont \u00e9t\u00e9 isol\u00e9s pour la premi\u00e8re fois \u00e0 partir du jaune de Vanisan et appartiennent aux d\u00e9riv\u00e9s de l'ionone. Dans les exp\u00e9riences de criblage de l'activit\u00e9 ci-dessus, seuls les compos\u00e9s 7-9 ont montr\u00e9 une faible inhibition de l'\u03b1-glucosidase. Les compos\u00e9s 10 \u00e0 13 ont des taux d'\u00e9limination \u00e9lev\u00e9s pour les radicaux ABTS, DPPH et hydroxyle, ce qui indique leur excellente activit\u00e9 antioxydante in vitro. Les compos\u00e9s 10 et 13 font partie des acides ph\u00e9noliques \u00e0 petites mol\u00e9cules, tandis que les compos\u00e9s 11 et 12 sont des d\u00e9riv\u00e9s styr\u00e8ne-\u03b1-pyranone typiques des ph\u00e9nols de Sanghuang, ce qui sugg\u00e8re que l'activit\u00e9 antioxydante des compos\u00e9s 10 \u00e0 13 provient des groupes hydroxyle ph\u00e9noliques de leur structure. Les compos\u00e9s 10 et 11 ont \u00e9galement montr\u00e9 de bons effets inhibiteurs sur la xanthine oxydase, tandis que le compos\u00e9 17 a montr\u00e9 une bonne activit\u00e9 inhibitrice sur l'alpha glucosidase. En r\u00e9sum\u00e9, cette \u00e9tude a permis d'enrichir la composition chimique des produits de fermentation solides du Vanisan Yellow, jetant ainsi les bases de son d\u00e9veloppement et de son utilisation. Cependant, l'activit\u00e9 biologique des compos\u00e9s obtenus doit encore \u00eatre explor\u00e9e plus avant.<\/p>","protected":false},"excerpt":{"rendered":"
