Der findes omkring 400 arter p\u00e5 verdensplan, heraf 55 arter og 8 underarter i Kina. Denne plante har en medicinsk historie p\u00e5 mere end 2400 \u00e5r i folkemedicinen, hovedsageligt med virkningerne af at fjerne varme og afgifte, sprede blodstasis og lindre smerter og fordrive vind og fugt. Planterne i Primus-sl\u00e6gten indeholder hovedsageligt naphthoquinon-, flavonoid-, kaempferol- og phloroglucinol-komponenter, hvoraf phloroglucinol-komponenterne har tiltrukket sig stor opm\u00e6rksomhed p\u00e5 grund af deres nye kemiske struktur og forskellige farmakologiske aktiviteter.<br \/>\nHypericum scarrum er en fler\u00e5rig urt af Hypericum, som er endemisk for Xinjiang, Kina, og som kun er udbredt i Tianshan-bjerget, Altar-bjerget Taishan-bjerget, det forreste bjerg i Talbahatai-bjerget og mellemliggende bjergomr\u00e5der. For yderligere at afklare det farmakologiske stofgrundlag og s\u00f8ge efter blyforbindelser med nye strukturer og god farmakologisk aktivitet isolerede, rensede og strukturelt identificerede denne unders\u00f8gelse de kemiske komponenter i petroleumsetherekstraktet fra ethanolekstraktet af luftdelen af Scutellaria barbata og testede den beskyttende aktivitet af hver forbindelse mod glutamatinduceret neuronal skade.<\/p>\n<p>I denne artikel er der foretaget en unders\u00f8gelse af den kemiske sammens\u00e6tning af ethanolekstraktet af luftdelen af den gyldne fersken med grove grene. I alt 10 phloroglucinolforbindelser blev isoleret og identificeret, hvoraf forbindelse 1 er en ny forbindelse. Og den neurobeskyttende aktivitet af hver forbindelse blev testet, og det viste sig, at forbindelserne 5 og 6 havde en vis beskyttende virkning p\u00e5 glutamatinduceret neuronal skade ved en koncentration p\u00e5 10 \u03bc M. Forbindelse 5 havde samme aktivitet som den positive kontrol resveratrol. Derudover er phloroglucinolforbindelser for det meste farvel\u00f8se olieagtige forbindelser med flere kirale centre, hvilket g\u00f8r det vanskeligt at bestemme deres absolutte konfigurationer ved hj\u00e6lp af klassiske r\u00f8ntgen-enkeltkrystaldiffraktionseksperimenter. De kan dog bestemmes ved hj\u00e6lp af sammenlignende eksperimenter og beregning af ECD-spektre.<\/p>","protected":false},"excerpt":{"rendered":"<p>Study on the components of phloroglucinol in rough branch golden peach The plants of the Guttiferae family and the Hypericum genus are distributed throughout the country, especially in East China, West China, northern Sichuan, Guizhou, Xinjiang, and other areas where they are more concentrated.
