Det er en medicinsk og spiselig plante; blade af r\u00e6vehaletr\u00e6 indeholder masser af aktive stoffer som flavonoider, polyfenoler, flygtige olier og polysaccharider, som har antioxidante, antibakterielle, anti-tumor og anti-inflammatoriske virkninger. P\u00e5 nuv\u00e6rende tidspunkt fokuserer forskningen i bladene fra Eucommia ulmoides hovedsageligt p\u00e5 udvinding af aktive ingredienser, farmakologiske virkninger og anvendelser i f\u00f8devareforarbejdning. Polysaccharider er de vigtigste funktionelle komponenter i bladene, og pektinindholdet er s\u00e5 h\u00f8jt som 35,53%. Forskningen i polysaccharider i bladene af stinkende tr\u00e6 fokuserer hovedsageligt p\u00e5 ekstraktion, antioxidant og antiinflammatoriske egenskaber af syreopl\u00f8selige og vandopl\u00f8selige polysaccharider. Shi et al. sammenlignede virkningerne af syreekstraktion, alkaliekstraktion og ammoniumoxalat-ultralydsassisteret ekstraktion p\u00e5 antioxidantaktiviteten af tofu-tr\u00e6pektin. Resultaterne viste, at alkaliekstraktionsmetoden havde den bedste evne til at fjerne frie DPPH-radikaler og hydroxylradikaler, og dens antioxidantaktivitet var bedre end de to andre ekstraktionsmetoder. Den vigtigste forskning i alkaliopl\u00f8selige polysaccharider i bladene af r\u00e6vehaletr\u00e6 er fokuseret p\u00e5 polysaccharidekstraktion, og ekstraktionsprocessen er ikke blevet systematisk unders\u00f8gt. Der har dog ikke v\u00e6ret nogen rapporter om antitumoraktiviteten af alkali-opl\u00f8selige polysaccharider i Kina.<br \/>\nDenne artikel har til form\u00e5l at udvikle og udnytte polysaccharidressourcerne i Eucommia ulmoides fuldt ud ved at bruge resterne af polysaccharider, der er udvundet med folinsyremetoden fra Eucommia ulmoides, som r\u00e5materiale. Enkeltfaktor- og responsoverfladeeksperimenter blev udf\u00f8rt for at optimere udvindingsprocessen af alkalisk opl\u00f8selige polysaccharider (PLAP) fra Premna puberula Pamp-blade og for at unders\u00f8ge PLAP's in vitro-antioxidantkapacitet og antitumoraktivitet. M\u00e5let er at give teoretisk st\u00f8tte til at maksimere udnyttelsen af Eucommia ulmoides-ressourcer og dens anvendelse inden for funktionel f\u00f8devareforskning og farmaceutiske omr\u00e5der.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4876\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/1-101.png\" alt=\"\" width=\"1047\" height=\"295\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/1-101.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/1-101-768x216.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4877\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/2-87.png\" alt=\"\" width=\"1047\" height=\"336\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/2-87.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/2-87-768x246.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4878\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/3-84.png\" alt=\"\" width=\"1047\" height=\"394\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/3-84.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/3-84-768x289.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4879\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/4-72.png\" alt=\"\" width=\"1047\" height=\"351\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/4-72.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/4-72-768x257.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4880\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/5-68.png\" alt=\"\" width=\"1047\" height=\"646\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/5-68.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/5-68-768x474.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4881\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/6-60.png\" alt=\"\" width=\"1047\" height=\"377\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/6-60.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/6-60-768x277.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4882\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/7-56.png\" alt=\"\" width=\"1047\" height=\"321\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/7-56.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/7-56-768x235.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4883\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/8-49.png\" alt=\"\" width=\"1047\" height=\"364\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/8-49.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/8-49-768x267.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-4884\" src=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/9-44.png\" alt=\"\" width=\"1047\" height=\"715\" srcset=\"https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/9-44.png 1047w, https:\/\/longchangextracts.com\/wp-content\/uploads\/2024\/08\/9-44-768x524.png 768w\" sizes=\"(max-width: 1047px) 100vw, 1047px\" \/>Dette eksperiment brugte resterne fra bladene af Eucommia ulmoides ved hj\u00e6lp af syreekstraktionsmetode som r\u00e5materiale og NaOH-opl\u00f8sning som ekstraktionsopl\u00f8sning.
