Xisha-\u00f8erne er rige p\u00e5 medicinske planteressourcer, og blandt dem har Euphorbia relativt mange medicinske planter, som kan bruges som varmeafledende urter. Lokale beboere langs Hainans kyst bruger Euphorbia som varmeudrensende og afgiftende medicin til at behandle sygdomme som dysenteri og diarr\u00e9. I de indledende eksperimenter blev det konstateret, at r\u00e5ekstraktet af Seaside Euphorbia har god antiinflammatorisk aktivitet og kan h\u00e6mme produktionen af NO af musemonocytter RAW264.7 induceret af lipopolysaccharid (LPS) in vitro (med en h\u00e6mningsgrad p\u00e5 83,97% ved en koncentration p\u00e5 200 \u03bc g\/mL). For at forst\u00e5 de vigtigste aktive stoffer i Seaside Euphorbia unders\u00f8gte denne unders\u00f8gelse den kemiske sammens\u00e6tning, in vitro-antiinflammatorisk aktivitet og cytotoksisk aktivitet af de overjordiske dele af Seaside Euphorbia.<\/p>\n<p>P\u00e5 baggrund af tidligere forskning unders\u00f8gte vi den kemiske sammens\u00e6tning og farmakologiske aktivitet af Euphorbia hainanensis. I alt 18 forbindelser, herunder sesquiterpener, messing, steroider, triterpener, peptider og andre strukturelle typer, blev isoleret fra ethylacetatfraktionen af ethanolekstrakt, og en antiinflammatorisk aktiv forbindelse 6 \u03b2 - hydroxycinnamolacton blev opdaget (2). De 18 forbindelser, der blev opn\u00e5et i denne unders\u00f8gelse, blev alle isoleret for f\u00f8rste gang fra Euphorbia benthamiana. Bortset fra forbindelserne 10, 13, 14 og 17 blev de andre forbindelser ogs\u00e5 isoleret for f\u00f8rste gang i Euphorbia-sl\u00e6gten. Forbindelse 1 er et nyt naturprodukt, og de relevante kernemagnetiske resonansdata for denne forbindelse blev suppleret i denne artikel. Gennem denne unders\u00f8gelse har vi f\u00e5et en grundl\u00e6ggende forst\u00e5else af de vigtigste kemiske komponenter i ethylacetatekstraktet af Seaside Euphorbia, hvilket giver et videnskabeligt grundlag for dets folkemedicinske brug.<\/p>","protected":false},"excerpt":{"rendered":"<p>Studies on the chemical constituents of Euphorbia officinalis from the Xisha Islands The investigation team of the &#8220;Nanfeng Special Project&#8221;
