Glycosides muaj qee cov lwg me me uas ib qho qab zib txuas nrog rau lwm yam. Glycosides ua si ntau txoj haujlwm tseem ceeb hauv cov kab mob muaj sia. Feem ntau cov nroj tsuag khaws cov tshuaj tseem ceeb hauv daim ntawv uas tsis muaj zog glycosides.
Thaum cov tshuaj no xav tau, cov glycosides khi rau dej thiab ib qho enzyme thiab qab zib feem raug sib cais, ua rau cov tshuaj khes mis siv. Ntau yam ntawm cov nroj tsuag glycosides yog siv ua tshuaj.
Cov glycoside molecule yog tsim los ntawm ob ntu - ib feem qab zib, uas yog hu ua glycon, thiab ib feem tsis muaj suab thaj, uas paub tias yog aglycone lossis noob.
Muaj txiaj ntsig thiab hom glycosides
Glycosides uas muaj nyob hauv cov nroj tsuag tshuaj, nyob ntawm cov tshuaj lom neeg qhov xwm txheej ntawm cov aglycone tau muab faib ua ntau pawg neeg tseem ceeb.
Flavonoids glycosides - lawv aglycones yog flavones, flavonols, thiab lwm yam. Lawv lub npe los ntawm "flavus" - daj, raws li lawv tau xim los ntawm daj ntseg daj mus rau daj-txiv kab ntxwv. Cov xim muaj ntau yam thiab pom hauv yuav luag txhua cov nroj tsuag thiab qhov chaw cog.
Lawv muab cov xim daj rau cov paj, tab sis kuj pom muaj nyob hauv cov nplooj, cov hauv paus hniav thiab txiv hmab txiv ntoo. Cov glycosides ntau ntxiv kom muaj kev ruaj khov ntawm cov hlab ntsha capillary thiab nce lawv cov elasticity.
Vim li no, lawv raug siv rau kev los ntshav ntawm ntau lub hauv paus pib, tab sis kuj yog kev tiv thaiv kev tiv thaiv rau kev pib mob sclerosis ntawm cov hlab ntsha. Lawv txhawb lub plawv, txo cov ntshav siab. Flavonoids glycosides yog cov tshuaj tiv thaiv ntuj tseem ceeb - lawv tiv thaiv vitamin C los ntawm oxidation.
Phenolic glycosides - lawv cov aglycones yog phenols lossis phenolic acids. Lawv pom feem ntau nyob hauv cov nroj tsuag ntawm Willow thiab Pyrenean tsev neeg. Qee qhov phenolic glycosides muaj pov thawj ntawm choleretic thiab biliary kev txiav txim.
Anthocyanin glycosides - cov pab pawg no suav nrog cov xim liab, xiav thiab xiav xim muaj nyob hauv cov txiv hmab txiv ntoo thiab cov paj ntawm ntau cov nroj tsuag. Lawv cuam tshuam qhov permeability ntawm capillaries, muaj cov tshuaj tiv thaiv kev tiv thaiv thiab siv qee qhov teeb meem qhov muag.
Lawv nce pom tseeb tseeb txawm tias nyob hauv lub teeb qis. Anthocyanins muaj cov haujlwm tshaj tawm hauv qhov no glycosidesmuaj nyob rau hauv cov txiv hmab txiv ntoo ntawm bilberries.
Anthraglycosides - pom feem ntau hauv tsev neeg Lapad, Taum, Brooches, Creams thiab Buckthorn. Cov no glycosides Tau ntev tau paub tias yog mob laxatives los yog purgatives rau kev cem quav.
Mob plawv glycosides - Lawv lub npe los ntawm lawv cov nyhuv tshwj xeeb rau lub siab nqaij. Nrog rau lawv cov txiaj ntsig zoo nyob rau hauv lub siab, lawv muaj tshuaj lom ntau, uas yog vim li cas lawv txoj kev siv yuav tsum nyob hauv kev saib xyuas kev kho mob.
Cov nus muag glycosides - hais txog 200 lub tebchaw tau paub nyob hauv pab pawg no. Lawv tau faib ntau nyob rau hauv cov tsev neeg Sedefchevi, Rozotsvetni, Slozhnotsvetni, Kartofovi, Sennikotsvetni. Qee qhov lawv raug txuas ntxiv muaj cov tshuaj antispasmodic thiab diuretic, thaum lwm tus txo cov hlab ntshav.
Iridoid glycosides - muaj qhov iab heev. Qee ntawm lawv yog cov tshuaj tua kab mob muaj zog nrog kev ua kom tiav thiab cov tshuaj tua kab mob. Lwm tus neeg ua rau mob siab, lwm tus muaj qhov ua kom pom tseeb. Qee qhov iridoid glycosides muaj cov tshuaj los tiv thaiv thiab hypotensive.
Thioglycosides - yog glycosides uas muaj cov leej faj. Nyob rau hauv kev cuam tshuam ntawm cov enzymes, lawv tawg thiab tso tawm cov roj tseem ceeb, uas ua rau cov nqaij mos thiab tawv nqaij ua rau puas. Lawv muaj cov antifungal thiab bacteriostatic kev ua, thiab qee qhov ntawm lawv muaj choleretic nyhuv.
Cyanogenic glycosides - thaum lub sijhawm ua rau lawv xaim lawv emit hydrogen cyanide. Lawv muaj nyob hauv cov noob, nplooj thiab keeb kwm ntawm qee cov nroj tsuag.
Los ntawm glycosides
Raws li nws hloov tawm, glycosides pom muaj nyob hauv cov nroj tsuag tshuaj ntsuab thiab tshuaj ntsuab, txiv hmab txiv ntoo thiab zaub. Txhua cov tshuaj ntsuab los yog txiv hmab txiv ntoo muaj qee yam hom glycoside, uas txiav txim qee cov txiaj ntsig zoo.
Raug mob los ntawm glycosides
Qee qhov sau glycosides tsis tsuas yog pab tau tab sis kuj tseem muaj kev phom sij. Piv txwv, hydrogen cyanide raug tso tawm ntawm cyanogenic glycosides.
Vim li no, kev siv tshuaj ntsuab yuav tsum tau nyob hauv kev saib xyuas kev noj qab haus huv thiab yuav tsum tsis txhob ntau tshaj qhov tau qhia txhua hnub kom tsis txhob muaj qhov cuam tshuam tsis zoo.
