Ntshiab Ntuj Artemisia Annua Roj rau Kev Kho Mob

piav qhia luv luv:

ue mus rau lub xub ntiag ntawm cov cim sesquiterpene endoperoxide lactone artemisinin (Qinghaosu), yog ib qho tseem ceeb tshaj plaws cog-derived tshuaj nyob rau hauv kev kho mob ntawm chloroquine-resistant thiab cerebral malarias, cov nroj tsuag yog cropped rau ib tug loj teev nyob rau hauv Tuam Tshoj, Nyab Laj, Qaib ntxhw. , Iran, Afghanistan, thiab Australia. Hauv Is Nrias teb, nws tau cog qoob loo los ntawm kev sim hauv cheeb tsam Himalayan, nrog rau cov xwm txheej kub thiab subtropical [3].

Cov roj tseem ceeb uas yog nplua nuj nyob rau hauv mono- thiab sesquiterpenes sawv cev rau lwm qhov ntawm cov khoom lag luam muaj txiaj ntsig [4]. Dhau li ntawm qhov kev hloov pauv tseem ceeb hauv nws cov feem pua ​​​​thiab cov muaj pes tsawg leeg tau tshaj tawm, nws tau ua tiav los ntawm ntau cov kev tshawb fawb uas feem ntau cuam tshuam txog kev ua haujlwm ntawm cov kab mob thiab cov tshuaj tua kab mob. Cov kev tshawb fawb sib txawv tau tshaj tawm txog niaj hnub siv cov kev sib txawv thiab sim cov kab mob sib txawv; Yog li ntawd, kev sib piv kev txheeb xyuas ntawm lub hauv paus quantitative yog qhov nyuaj heev. Lub hom phiaj ntawm peb qhov kev tshuaj xyuas yog txhawm rau sau cov ntaub ntawv ntawm kev ua haujlwm antimicrobial ntawmA. xyoovolatiles thiab nws cov khoom tseem ceeb los pab txhawb rau yav tom ntej ntawm kev sim microbiological hauv daim teb no.

2. Nroj faib thiab tawm los ntawm cov Volatiles

Essential (volatile) roj ntawmA. xyootuaj yeem ncav cuag 85 kg / ha. Nws yog synthesized los ntawm secretory hlwb, tshwj xeeb tshaj yog nyob rau hauv lub Uppermost foliar feem ntawm cov nroj tsuag (sab saum toj 1/3 ntawm kev loj hlob ntawm maturity) uas muaj yuav luag ob npaug yog piv nrog cov nplooj qis. Nws tau tshaj tawm tias 35% ntawm cov nplooj loj hlob tuaj yog npog nrog cov qog capitate uas muaj cov terpenoidic volatile constituents. Cov roj tseem ceeb los ntawmA. xyooyog faib, nrog 36% ntawm tag nrho los ntawm sab sauv peb ntawm nplooj, 47% los ntawm nruab nrab peb, thiab 17% los ntawm qis peb, tsuas yog cov kab nyob rau hauv lub ntsiab qia sab tua thiab cov hauv paus hniav. Cov txiaj ntsig ntawm cov roj feem ntau nyob nruab nrab ntawm 0.3 thiab 0.4% tab sis nws tuaj yeem ncav cuag 4.0% (V / W) los ntawm cov genotypes xaiv. Ntau qhov kev tshawb fawb tau tso cai qhov xaus tiasA. xyooCov qoob loo tuaj yeem raug sau ntau ua ntej pib paj kom tau txais cov txiaj ntsig siab ntawm artemisinin thiab cov qoob loo yuav tsum tau tso cai kom ua tiav kom tau txais cov txiaj ntsig siab ntawm cov roj tseem ceeb [5,6].

Tawm los (tshuaj ntsuab thiab cov ntsiab lus roj tseem ceeb) tuaj yeem nce ntxiv nrog nitrogen thiab qhov loj tshaj plaws tau txais nrog 67 kg N / ha. Kev nce siab ntawm cov nroj tsuag muaj peev xwm nce cov roj tseem ceeb ntawm thaj chaw, tab sis cov txiaj ntsig tseem ceeb tshaj plaws (85 kg roj / ha) tau ua tiav los ntawm qhov nruab nrab ntom ntawm 55,555 nroj tsuag / ha tau txais 67 kg N / ha. Thaum kawg hnub cog thiab lub sijhawm sau qoob loo tuaj yeem cuam tshuam qhov siab tshaj plaws ntawm cov roj tseem ceeb uas tsim tawm [6].

3. Tshuaj Profile ntawm Cov Roj Tseem Ceeb

Cov roj yam tseem ceeb, feem ntau tau los ntawm hydrodistillation ntawm lub paj saum toj kawg nkaus, tshuaj xyuas nrog GC-MS, qhia txog qhov sib txawv ntawm qhov zoo thiab qhov muaj pes tsawg leeg.

Chemical profile feem ntau cuam tshuam los ntawm lub caij sau qoob loo, chiv thiab pH ntawm cov av, kev xaiv thiab theem ntawm kev ziab, qhov chaw nyob, chemotype lossis subspecies, thiab kev xaiv ntawm cov nroj tsuag lossis genotype lossis extraction method. Hauv Rooj1, cov ntsiab lus tseem ceeb (> 4%) ntawm cov qauv tshawb xyuas tau tshaj tawm.
