Anthocyanin yog dab tsi
Anthocyaninhais txog xim liab-liab doog-xiav xiav flavonoid xim uas pom hauv cov nroj tsuag. Nws yog dej-soluble molecule. Nws cov ntsiab lus tseem ceeb yog cov flavylium ion. Nws tuaj yeem pom hauv txheej txheej sab nrauv ntawm cov qauv ntoo xws li txiv hmab txiv ntoo, paj, nplooj, kav, thiab cag. Cyanidin yog qhov anthocyanin loj uas pom hauv nroj tsuag. Peonidin, delphinidin, petunidin, pelargonidin, thiab malvidin yog qee yam piv txwv ntawm anthocyanin.Txiv hmap, acai, blueberry, bilberry, blackcurrant, Cherry, thiab pob kws ntshav yog cov txiv hmab txiv ntoo uas muaj ntau dua anthocyanin. Cov txiv kab ntxwv muaj nyob hauv daim duab 1.
Cov xim thiab ruaj khov ntawm cov xim pleev xim yog cuam tshuam los ntawm pH, kub, thiab lub teeb. Anthocyanin yog cov tshuaj antioxidant uas muaj zog tiv thaiv cov nroj tsuag ntawm UV. Vim muaj cov antioxidant nyhuv, anthocyanin siv rau hauv cov tshuaj lag luam uas cuam tshuam rau lub plawv kev noj qab haus huv, ua haujlwm los tiv thaiv qog noj ntshav, thiab tiv thaiv lub cev. Hauv cov kab mob acidic, anthocyanin tshwm li liab, thiab nws dhau los ua xiav hauv qhov pib mob.
Anthocyanidin yog dab tsi
Anthocyanidin yog hais txog cov nroj tsuag xim uas tsim los ntawm hydrolysis ntawm anthocyanin thiab cim ntawm cov flavonoid tib yam li anthocyanin tsis muaj ketone pawg. Yog li, nws yog daim ntawv aglycone ntawm anthocyanin. 31 monomeric anthocyanidins tau txheeb pom kom deb li deb thiab lawv feem ntau ua raws li cyanidin. Lwm tus yog ua raws delphinidin thiab pelargonidin. Lub hauv paus ntsiab lus ntawm anthocyanidin yog qhia hauv daim duab 2.
Cov xim ntawm anthocyanidin yog tam sim no nyob rau hauv cov kab mob acidic, thiab nws tsis muaj xim nyob rau hauv cov neeg mob. Txij li thaum anthocyanidin yog ib qho tshuaj antioxidant, nws kuj tseem siv los ua cov tshuaj suav tshuaj. Ob qho tshuaj tiv thaiv anthocyanin thiab anthocyanidin yog siv los ua cov tshuaj lom neeg rau hauv kev lag luam zaub mov hauv cov lej E. Ob lub tebchaw muaj cov tshuaj tua kabmob ua kom zoo ntxiv, thiab lawv txhim kho kev pom kev zoo thiab lub paj hlwb.

Anthocyanidin: Anthocyanidin yog hais txog xim tsob nroj tsim los ntawm hydrolysis ntawm anthocyanin.
Glycosylation
Anthocyanin: Anthocyanin yog glycosylated derivative.
Anthocyanidin: Anthocyanidin yog aglycones ntawm anthocyanin.
Cov nyhuv ntawm pH
Anthocyanin: Anthocyanin tshwm hauv cov xim liab hauv acidic pH thiab xiav hauv pH yooj yim.
Anthocyanidin: Cov xim ntawm anthocyanidin yog tam sim no nyob rau hauv cov kab mob acidic thiab nws tsis muaj xim nyob hauv cov mob uas yooj yim.
Xaus
Anthocyanin thiab anthocyanidin yog ob hom xim liab-xiav xiav pom hauv cov nroj tsuag. Qhov tseem ceeb tseem ceeb ntawm ob qho anthocyanin thiab anthocyanidin yog flavylium ion. Anthocyanin yog daim ntawv glycosylated ntawm anthocyanidin. Anthocyanidin yog muaj li ntawm aglycons. Qhov sib txawv tseem ceeb ntawm anthocyanin thiab anthocyanidin yog qib ntawm glycosylation.
Cov zaub ntsuab puas muaj anthocyanin?
Hlais nplej(Spinacia oleracea L.) yog dav cog ua ib qho kev lag luam muaj txiaj ntsig ntsuab zaub ntsuab rau cov tshiab thiab kev ua noj. Lub txiv duaj liab-nplooj liab pom tias muaj anthocyanin ntau ntau nyob hauv daim nplooj thiab nplooj nplaim paj. Txawm li cas los xij, cov txheej txheem molecular ntawm anthocyanin synthesis hauv hom no tseem tsis tau txiav txim siab. Hauv qhov kev kawm tam sim no, peb tshawb xyuas cov xim tsim thiab pom cov anthocyanin biosynthetic noob zaub xyaw pob hauv zaub ntsuab.
Cov dib liab puas muaj anthocyanin?
Tag nrho cov ntsiab lus anthocyanin nyob rau hauv lub rind liab yog 0.0334 mg L-1 thaum lub sij hawm cov xim liab daj yog 0.0668 mg L-1. Tag nrho cov ntsiab lus ntawm flavonoids nyob rau hauv lub liab liab liab rind yog 0.7369 g mL-1, thaum nyob hauv lub txiv daj daj rind yog 0.3296 g mL-1. Tag nrho cov ntsiab lus phenolic ntawm liab liab liab rind yog 0.3669 g mL-1, thaum nyob hauv lub rind daj txiv ntoo yog 0.2273 g mL-1. Hauv ob qho ntawm xim liab thiab daj liab txiv kab ntxwv rind, qhov tso tawm siab tshaj plaws ntawm flavonoid thiab phenolic qib pom nyob rau hauv kev hloov pauv ntawm chitosan huab hwm huab hwm 0.4 grams. Cov flavonoid ntau tshaj plaws cov ntsiab lus tso tawm yog 0.0638 g mL-1 hauv cov txiv duav liab rind thiab 0.0702 g mL-1 hauv cov txiv kab ntxwv daj. Cov ntsiab lus siab tshaj plaws ntawm phenolic tso tau yog 0.0321 g mL-1 hauv cov kab liab liab liab thiab 0.0408 g mL-1 hauv cov txiv ntoo daj daj rind.
