Unders\u00f8gelse af kemiske komponenter og antioxidantaktivitet i salth\u00e5rede tr\u00e6blade
\nRhus chinensis Mill., ogs\u00e5 kendt som Galla chinensis, wutong amurensis og Rhus chinensis, tilh\u00f8rer familien Rhus chinensis, som er udbredt i Kina undtagen i det nord\u00f8stlige Kina, Indre Mongoliet og Xinjiang. If\u00f8lge \"Compendium of Materia Medica\" kan r\u00f8dder, st\u00e6ngler, blade og hele kroppen af Yanfu-tr\u00e6 bruges som medicin til at behandle og forebygge sygdomme som diarr\u00e9, dysenteri, kolik, hepatitis osv. I \u00f8jeblikket bruges afkoget af Yanfu-tr\u00e6ets r\u00f8dder mest i klinisk praksis til behandling af koronar hjertesygdom, angina pectoris, lungeabsces og kronisk diarr\u00e9 hos b\u00f8rn. Forskning har vist, at den kemiske sammens\u00e6tning af Rhus chinensis hovedsageligt omfatter lignin, flavonoider, fenoler, triterpener osv. I \u00f8jeblikket fokuserer forskningen hovedsageligt p\u00e5 Rhus chinensis' r\u00f8dder, mens der kun er forsket lidt i Rhus chinensis' blade. If\u00f8lge eksisterende forskningsrapporter blev der kun isoleret 13 forbindelser, herunder 6 flavonoider, 4 fenolsyrer og 3 triterpenoider, fra bladene af Saltwood. Ethylacetatekstraktet af Saltwoods blade viste god antioxidantaktivitet, og polyfenoler viste sig at v\u00e6re de vigtigste aktive ingredienser. For yderligere at afklare og udforske de aktive ingredienser i Schisandra chinensis unders\u00f8gte denne unders\u00f8gelse systematisk den kemiske sammens\u00e6tning af Schisandra chinensis-blade og udf\u00f8rte in vitro-antioxidantaktivitetseksperimenter p\u00e5 de isolerede og identificerede forbindelser, hvilket giver et teoretisk grundlag for bedre udvikling og udnyttelse af v\u00e6rdien af Schisandra chinensis.<\/p>\n

\"\"\"\"\"\"\"\"I denne unders\u00f8gelse blev 15 forbindelser isoleret fra ethylacetat-ekstraktionsfasen af blade af saltbarktr\u00e6, herunder 1 ny forbindelse og 14 kendte forbindelser. Forbindelserne 2, 4, 6, 7, 8, 13 og 15 blev isoleret fra saltbarkplanter for f\u00f8rste gang. Resultaterne af in vitro-antioxidantaktivitetseksperimenter viste, at forbindelserne 9, 10, 11 og 14 udviste god rensningsaktivitet mod DPPH- og ABTS-frie radikaler, mens forbindelse 6 viste god rensningsaktivitet mod ABTS-frie radikaler. Blandt dem havde forbindelserne 9 og 10 den st\u00e6rkeste rensningsaktivitet for frie radikaler, st\u00e6rkere end den positive kontrol VC. Yderligere analyse af strukturerne af forbindelser med antioxidantaktivitet afsl\u00f8rede, at forbindelse 11 er lignin, mens de resterende forbindelser 6, 9, 10 og 14 tilh\u00f8rer polyfenoliske forbindelser. Derfor spekuleres der i, at polyfenoliske forbindelser er de vigtigste aktive ingredienser i in vitro-antioxidantaktiviteten af saltbarkblade. Resultaterne af denne eksperimentelle unders\u00f8gelse belyste de vigtigste funktionelle komponenter i antioxidantaktivitet i saltede tr\u00e6blade, berigede den kemiske sammens\u00e6tning og antioxidantaktivitetsforskningen af saltede tr\u00e6blade og gav et teoretisk grundlag for den materielle basisforskning af saltede tr\u00e6blade.<\/p>","protected":false},"excerpt":{"rendered":"
