Hook Et Arn., ogs\u00e5 kendt som f\u00e5rehorn, karpeoliven, gedehorn, er en plante af Apocynaceae-familien i Strophanthus-sl\u00e6gten. Den er hovedsageligt udbredt i provinser som Hainan, Yunnan, Guizhou, Guangdong og Fujian i Kina samt i sydasiatiske lande som Laos og Vietnam. Den vokser vildt i bakkede og bjergrige omr\u00e5der, i sparsomme skove langs vejene eller i buske p\u00e5 bjergskr\u00e5ninger. Hele planten af Yangjiaoao er giftig og bruges som et medicinsk hjertestimulerende middel. Den kan bruges til at behandle sygdomme som arteriosklerose, forstuvninger, leddegigt, slangebid osv. Den kan ogs\u00e5 bruges som insekticid i landbruget. Forskning har vist, at Yangjiaoao hovedsageligt indeholder hjerteglykosider samt kemiske komponenter som sesquiterpener, triterpener og lignaner. Ekstraktet af Yangjiaoao har hjertestyrkende, antibakterielle, antioxidante og insektdr\u00e6bende virkninger, og hjerteglykosider har biologiske aktiviteter som antitumor og hjertestyrkende. For yderligere at forbedre den grundl\u00e6ggende forskning i de kemiske stoffer i Yangjiaobao og yderligere udforske de kemiske komponenter i denne plante og dens antiinflammatoriske aktivitet brugte denne unders\u00f8gelse silicagel, Sephadex LH-20-gel og andre kromatografiske separationsteknologier til at adskille ethylacetatekstraktet af ethanolekstraktet af Yangjiaobao-stammen og brugte LPS-induceret musemonocyt-makrofag RAW264.7-celleinflammationsmodel til at teste den antiinflammatoriske aktivitet af dens kemiske komponenter in vitro.<\/p>\n<p>Denne unders\u00f8gelse isolerede og identificerede 13 forbindelser (1-4 og 6-13) fra f\u00e5rehornsst\u00e6ngler for f\u00f8rste gang. Blandt dem rapporterede litteraturen, at pentacykliske triterpenoid vedbend-saponiner (1) har antitumor-, antidepressiv- og antibakteriel aktivitet, og der er behov for yderligere forskning. Resultaterne af screeningen af den antiinflammatoriske aktivitet i den LPS-inducerede musemonocyt-makrofag RAW264.7-model viste, at terpentin (5) havde en betydelig antiinflammatorisk aktivitet med en IC50-v\u00e6rdi p\u00e5 18,09 \u00b1 1,09 \u03bc M. Denne unders\u00f8gelse beriger forbindelsestyperne i Yangjiaoao og giver et grundlag for forskning i dens antiinflammatoriske aktivitet.<\/p>","protected":false},"excerpt":{"rendered":"<p>Study on the Chemical Composition and Anti inflammatory Activity of Sheep Horn and Stubborn Stem Strophanthus divaricatus (Lour.)
