Unders\u00f8gelse af den kemiske sammens\u00e6tning og biologiske aktivitet af faste fermenteringsprodukter af Vanisan Yellow
\nSanghuang er en generel betegnelse for en stor klasse af h\u00e5rde por\u00f8se svampe, der er opkaldt efter deres v\u00e6kst p\u00e5 morb\u00e6rstammer og gulbrune frugtlegemer. Sanghuang er en ber\u00f8mt traditionel medicinsk svamp i Kina, og den tidligst registrerede medicinske anvendelse af Sanghuang kan spores tilbage til \"Shennong Bencao Jing\", hvor den omtales som \"Sanghuang-\u00f8re\". Det bruges til at behandle kvinders kollaps og diarr\u00e9 samt til at behandle m\u00e6nds feber og ogs\u00e5 til at behandle blodstase og r\u00f8dt blod. P\u00e5 grund af de mange forskellige store por\u00f8se bakterier med lignende farver og h\u00e5rdhed er det sv\u00e6rt at skelne dem fra hinanden, s\u00e5 der har v\u00e6ret stor uenighed om artsbestemmelsen af Sanghuang i lang tid. I de seneste \u00e5rtier er forskere gradvist n\u00e5et til enighed om klassificeringen af Sanghuangporus og mener, at den h\u00f8rer til Basidiomycota phylum, Agaricomycetes-ordenen, Hymenochaetales-ordenen, Hymenochaetaceae-familien og de store por\u00f8se svampe. En ny sl\u00e6gt, Sanghuangporus, er blevet etableret. P\u00e5 nuv\u00e6rende tidspunkt findes der 14 sorter af Sanghuang-svampe i sl\u00e6gten Sanghuang. Sammenlignet med andre sorter har Vanisan Sanghuang et h\u00f8jere indhold af aktive ingredienser, en bred vifte af biologiske aktiviteter og fordelen ved nem kunstig dyrkning, hvilket g\u00f8r den til en af de mest kommercielt tilg\u00e6ngelige sorter.
\nModerne forskning viser, at Phellinus igniarius har en r\u00e6kke biologiske aktiviteter, s\u00e5som anti-inflammatorisk og antioxidant, anti-tumor og immunregulering, antidiabetes, leverbeskyttelse og neurobeskyttelse. Det er en potentiel kilde til funktionelle f\u00f8devarer og terapeutiske l\u00e6gemidler. P\u00e5 nuv\u00e6rende tidspunkt fokuserer forskningen i de aktive ingredienser i Vanisan Yellow hovedsageligt p\u00e5 frugtlegemet, og der er relativt lidt forskning i den kemiske sammens\u00e6tning af faste fermenteringsprodukter. Derfor unders\u00f8gte dette eksperiment de kemiske komponenter i de faste fermenteringsprodukter fra Vanisan Yellow gennem systematiske separationsmetoder og evaluerede in vitro-antioxidantaktiviteten, xanthinoxidase og \u03b1-glucosidase-h\u00e6mmende aktivitet af de opn\u00e5ede forbindelser, hvilket giver et videnskabeligt grundlag for den videre udvikling af Vanisan Yellow.<\/p>\n

\nPolyfenoler, terpener, polysaccharider og andre stoffer i Sanghuang-svampe har rige farmakologiske aktiviteter og brede anvendelsesmuligheder. Litteraturgennemgang har imidlertid vist, at forskning i Sanghuangs kemiske sammens\u00e6tning hovedsageligt fokuserer p\u00e5 frugtlegemet, og der er relativt lidt forskning i den kemiske sammens\u00e6tning af Sanghuang fra fermenteringskilder. Derfor blev der i dette eksperiment isoleret 17 forbindelser fra det faste fermenteringsprodukt af Vanisan Yellow, og deres in vitro-antioxidantaktivitet, \u03b1-glucosidaseh\u00e6mmende aktivitet og xanthinoxidaseh\u00e6mmende aktivitet blev screenet. Forbindelserne 1-9 blev isoleret for f\u00f8rste gang fra Vanisan Yellow og h\u00f8rer til ionon-derivaterne. I ovenst\u00e5ende aktivitetsscreeningseksperimenter viste kun forbindelserne 7-9 svag \u03b1-glucosidaseh\u00e6mning. Forbindelserne 10-13 har h\u00f8je fjernelseshastigheder for ABTS-, DPPH- og hydroxylradikaler, hvilket indikerer deres fremragende in vitro-antioxidantaktivitet. Forbindelserne 10 og 13 tilh\u00f8rer sm\u00e5molekyl\u00e6re phenolsyrer, mens forbindelserne 11 og 12 er typiske styren-\u03b1-pyranonderivater af Sanghuang-phenoler, hvilket tyder p\u00e5, at antioxidantaktiviteten af forbindelserne 10-13 stammer fra de phenoliske hydroxylgrupper i deres struktur. Forbindelserne 10 og 11 viste ogs\u00e5 gode h\u00e6mmende virkninger p\u00e5 xanthinoxidase, mens forbindelse 17 udviste god h\u00e6mmende aktivitet p\u00e5 alfa-glucosidase. Sammenfattende har denne unders\u00f8gelse beriget den kemiske sammens\u00e6tning af de faste fermenteringsprodukter fra Vanisan Yellow og lagt grundlaget for udvikling og anvendelse af dem. Den biologiske aktivitet af de opn\u00e5ede forbindelser skal dog stadig udforskes yderligere.<\/p>","protected":false},"excerpt":{"rendered":"
