Amafutha Ahlanzekile Emvelo E-Artemisia Annua Yezokwelapha

incazelo emfushane:

ngenxa yokuba khona kwe-sesquiterpene endoperoxide eyingqayizivele i-lactone artemisinin (Qinghaosu), omunye wemithi ebaluleke kakhulu etholakala esitshalweni ekwelapheni i-chloroquine-resistant kanye ne-cerebral malaria, lesi sitshalo silinywa ngezinga elikhulu e-China, eVietnam, eTurkey. , i-Iran, i-Afghanistan, ne-Australia. E-India, itshalwa ngendlela yokuhlola ezindaweni zase-Himalaya, kanye nezimo ezipholile nezishisayo [3].

Amafutha abalulekile anothe ngama-mono- kanye nama-sesquiterpenes amelela omunye umthombo wenani lezentengiselwano elingase libe khona [4]. Ngaphandle kokwehluka okukhulu kwephesenti nokubunjwa kwayo kuye kwabikwa, iye yafakwa ngempumelelo ezifundweni eziningi ezithinta ikakhulukazi imisebenzi ye-antibacterial kanye ne-antifungal. Izifundo zokuhlola ezihlukahlukene ziye zabikwa kuze kube manje kusetshenziswa izindlela ezahlukene kanye nokuhlola ama-microorganisms ahlukene; ngakho-ke, ukuhlaziya okuqhathanisayo ngesisekelo sobuningi kunzima kakhulu. Inhloso yokubuyekeza kwethu ukufingqa idatha yomsebenzi we-antimicrobial ofA. unyakaama-volatiles kanye nezingxenye zawo ezinkulu ukusiza indlela yesikhathi esizayo yokuhlolwa kwe-microbiological kulo mkhakha.

2. Ukusatshalaliswa Kwezitshalo kanye Nesivuno Sokuguquguquka

Amafutha abalulekile (aguquguqukayo) weA. unyakaingafinyelela isivuno sika-85 kg/ha. Ihlanganiswa ngamaseli ayimfihlo, ikakhulukazi ingxenye yamaqabunga ephezulu kakhulu yesitshalo (phezulu 1/3 yokukhula ekuvuthweni) equkethe cishe inombolo ephindwe kabili uma iqhathaniswa namaqabunga aphansi. Kubikwa ukuthi u-35% weqabunga elivuthiwe limbozwe izindlala ze-capitate eziqukethe izakhi ze-terpenoidic volatile. Amafutha abalulekile avelaA. unyakaiyasatshalaliswa, ngama-36% engqikithi isuka engxenyeni yesithathu engenhla yamaqabunga, i-47% isuka kweyesithathu emaphakathi, no-17% isuka kweyesithathu ephansi, kube nenani elincane kuphela emahlumela aseceleni kwesiqu esikhulu nezimpande. Isivuno samafutha ngokuvamile sihluka phakathi kuka-0.3 no-0.4% kodwa singafinyelela ku-4.0% (V/W) kusuka kuma-genotypes akhethiwe. Ucwaningo oluningi luye lwavumela isiphetho salokhoA. unyakaIsitshalo singavunwa ngaphambi kokuqala kokuqhakaza kwezimbali ukuze sithole isivuno esikhulu se-artemisinin futhi isilimo kufanele sivunyelwe ukuvuthwa ukuze sithole isivuno esikhulu samafutha abalulekile [5,6].

Isivuno (izitshalo kanye nokuqukethwe kwamafutha abalulekile) kungandiswa nge-nitrogen eyengeziwe futhi ukukhula okukhulu kwatholakala ngo-67 kg N/ha. Ukukhula kokuminyana kwezitshalo kuvame ukukhuphula ukukhiqizwa kukawoyela obalulekile endaweni, kodwa isivuno esikhulu sikawoyela obalulekile (85 kg kawoyela/ha) sitholwe ngokuminyana okumaphakathi ezitshalweni ezingu-55,555 ngehektare ezithola u-67 kg N/ha. Ekugcineni usuku lokutshala nesikhathi sokuvuna kungaba nomthelela ekugxilweni okuphezulu kwamafutha abalulekile akhiqizwayo [6].

3. Iphrofayili Yekhemikhali Yamafutha Abalulekile

Amafutha abalulekile, ngokuvamile atholwe nge-hydrodistillation yeziqongo zezimbali, ahlaziywa nge-GC-MS, aveze ukuhluka okukhulu kokubili ekubunjweni kwekhwalithi nokwenani.

Iphrofayili yamakhemikhali ngokuvamile ithonywa isikhathi sokuvuna, umanyolo kanye ne-pH yenhlabathi, ukukhetha kanye nesigaba sezimo zokomisa, indawo yendawo, i-chemotype noma i-subspecies, nokukhethwa kwengxenye yesitshalo noma uhlobo lwe-genotype noma indlela yokukhipha. Kuthebula1, izakhi eziyinhloko (>4%) zamasampuli aphenyiwe ziyabikwa.
