Som traditionel kinesisk medicin er Liangfen Grass kendt som \"fe-gr\u00e6s\" og har virkningerne astringente, s\u00f8de, kolde, varmeudrensende, blodk\u00f8lende og afgiftende. Det er blevet udviklet til f\u00f8devarer, naturlige sundhedsprodukter og endda kliniske l\u00e6gemidler. Eksisterende forskning har vist, at dens r\u00f8dder, st\u00e6ngler, blade og blomster indeholder en stor m\u00e6ngde bioaktive stoffer, herunder polysaccharider, flavonoider, terpener, vitaminer og fenoler, som har en h\u00f8j ern\u00e6ringsm\u00e6ssig og medicinsk v\u00e6rdi.<\/p>\n<p>Fenoliske forbindelser spiller en vigtig rolle i plantev\u00e6kst og har st\u00e6rke beskyttende virkninger p\u00e5 forskellige organer i menneskekroppen. If\u00f8lge rapporter har forskere gennem forskning fundet ud af, at liangfen-gr\u00e6s indeholder hypoglyk\u00e6miske og hypertensive stoffer, herunder \u03b2 - sitosterol, stigmasterol, \u03b1 - og \u03b2 - amyloidproteiner, oleanolsyre, aristolochinsyre og \u03b2 - sitosterolglykosider. Samtidig har forskere identificeret ni aktive forbindelser fra vandekstraktet af liangfen-gr\u00e6s, herunder kaempferol, apigenin, koffeinsyre, protocatechuic acid, eugenic acid, vanillic acid, p-hydroxybenzoic acid, oleanolic acid og ursolic acid. Blandt dem anses koffeinsyre, protocatechuinsyre og kaempferol for at v\u00e6re vigtige komponenter i liangfen-gr\u00e6ssets antioxidantaktivitet, herunder reduktion af LDL-oxidation og inflammation, hvilket giver beskyttelse mod hjerte-kar-sygdomme.<\/p>\n<p>UPLC-Q-TOF-MS\/MS-teknologien (Ultra high performance liquid chromatography tandem quadrupole time-of-flight mass spectrometry) har fordelene ved h\u00f8j f\u00f8lsomhed, h\u00f8j opl\u00f8sning, h\u00f8j separationseffektivitet og kort analysetid. Samtidig kan den ogs\u00e5 indhente oplysninger om molekylv\u00e6gt, grundstofsammens\u00e6tning og ionfragmenter af forbindelser, som hurtigt kan bestemme forbindelsernes struktur. Det er blevet brugt i vid udstr\u00e6kning inden for l\u00e6gemiddelanalyse. P\u00e5 nuv\u00e6rende tidspunkt er sammens\u00e6tningen af polyfenoler i Sophora japonica ikke fuldt ud forst\u00e5et. I dette eksperiment blev UPLC-Q-TOF-MS\/MS-teknologi brugt til hurtigt og omfattende at analysere de kemiske komponenter i Sophora japonica, hvilket giver en vigtig reference til unders\u00f8gelsen af fenoliske kemiske komponenter i Sophora japonica.<\/p>\n<p>Denne unders\u00f8gelse etablerede en UPLC-Q-TOF-MS\/MS-metode til analyse af de polyfenoliske komponenter i Sophora japonica. Ved at analysere massespektrometriens r\u00e5data, herunder relativ molekylv\u00e6gt, retentionstid, element\u00e6r sammens\u00e6tning, fragmentioner og andre oplysninger, kombineret med referencestandarder, databaser og litteraturrapporter, blev 51 forbindelser identificeret og spekuleret. Det blev bekr\u00e6ftet, at de polyfenoliske komponenter i Sophora japonica hovedsageligt bestod af flavonoider, phenylpropanoidsyre og deres oligomerer, herunder caffeoylhexosid, salvianolsyre F og salvianolsyre H apigenin-6,8-di-C-hexosid, Chuanchenpi-ekstrakt, nobiletin-3-O - \u03b2 - D-glucosid, 20-deoxysalvianolsyre, 3-O-D-glucopyranosyl platydigenin-methylester og marstenacigenin A er ikke blevet rapporteret i relevant litteratur om kinesisk urtemedicin. Denne unders\u00f8gelse tyder p\u00e5, at disse ni forbindelser er blevet opdaget for f\u00f8rste gang i kinesisk urtemedicin. Forskningsresultaterne l\u00e6gger grundlaget for den grundl\u00e6ggende forskning og udvikling af effektive stoffer i urtemedicin og har en vigtig vejledende betydning for den videre udvikling af nye l\u00e6gemidler.<\/p>","protected":false},"excerpt":{"rendered":"<p>UPLC-Q-TOF-MS\/MS-analyse af kemiske komponenter af polyfenoler i Herba Sophorae Mesona chinensis Benth. er en urt af sl\u00e6gten Mesona af Labiatae, der er udbredt i det nord\u00f8stlige Indien, Syd\u00f8stasien, Taiwan, Kina, Fujian, Guangdong, Guangxi og Yunnan i Kina.
