Ntchito:

Betulin (CAS: 473-98-3) ndi chotsitsa kuchokera ku khungwa la mtengo woyera wa birch, womwe umadziwika kuyambira zaka za zana la 18 ndipo umafotokozedwa ndi mankhwala.Betulin anapezedwa ndi katswiri wa zamankhwala wa ku Germany-Russian Johann Tobias Lowitz.Iye anali wasayansi woyamba kuphunzira ndi kuzindikira betulin, ndipo pochita anali mmodzi wa oyamba kudzipatula yogwira chomera pophika.Betulin ndi chinthu chochokera ku chomera chomwe chimapangitsa khungwa la birch kukhala loyera.Betulin imateteza mitengo ya birch kuzinthu zachilengedwe, monga kutentha kwambiri, kuwononga tizilombo komanso ma radiation adzuwa.
Betulin ndi woyera crystalline ufa, sungunuka mu mowa, chloroform ndi benzene, sungunuka pang'ono m'madzi ozizira, petroleum ether.
Physiological zotsatira za betulin
1. Betulin ndi zotumphukira zake zawonetsa kuthekera kwakukulu ngati zida zamoyo mu HIV ndi chithandizo cha khansa.Amagwira ntchito posokoneza magawo amtsogolo a moyo wa kachilomboka ndipo amakhudzana ndi kulowa kwa ma virus ndi kukula ndi kukhwima.
2. Mankhwala oletsa anti-chotupa, omwe amachititsa mwachindunji mitundu ina ya maselo a chotupa kuyambitsa mapulogalamu owononga apoptosis, ndipo amatha kuchepetsa kukula kwa mitundu ingapo ya maselo otupa.
3. Betulin imatha kuchepetsa kunenepa kwambiri komwe kumabwera chifukwa cha zakudya, kuchepetsa lipids mu seramu ndi minofu, komanso kukulitsa chidwi cha mu-sulin k.
4. Amakhala ndi anti-inflammatory properties pazigawo zapamwamba kwambiri, ndipo zotsutsana ndi zotupa zimakhala makamaka chifukwa cha kuletsa njira zopanda neural gene.
5. Betulin imatha kuletsa kusasitsa kwa sterol regulatory element-binding proteins (SBERPs) mu vivo, potero amachepetsa biosynthesis ya cholesterol ndi mafuta acid.
6. Kuonjezera apo, Betulin ali ndi anti-inflammatory, anti-viral, amalepheretsa kusungunuka kwa mapuloteni mu ulusi wa tsitsi, kumapangitsa kuti tsitsi lowonongeka likhale lokongola, ndikulimbikitsa kukula kwa tsitsi.Betulin itha kugwiritsidwa ntchito m'mafakitale azakudya, zodzoladzola komanso zamankhwala.
Makampani opanga mankhwala:
Betulin amagwiritsidwa ntchito makamaka ngati mankhwala apakatikati, ndipo Betulin ndi zotumphukira zake ngati tizilombo toyambitsa matenda awonetsa kuthekera kwakukulu pochiza HIV ndi khansa.Pa nthawi yomweyo, izo ntchito antitussive ndi expectorant, mankhwala matupi awo sagwirizana rhinitis, kusowa tulo, maganizo, etc.
Makampani a Chakudya:
Pali maphunziro ogwiritsira ntchito ngati chosungira muzakudya za nyama.
Makampani opanga zodzoladzola:
Kulepheretsa kwa Betulin pa ntchito ya collagenase ndi kuchuluka kwa maselo a khungu kumasonyeza kuti ili ndi mphamvu yotsutsa kukalamba ndipo ingagwiritsidwe ntchito kuyeretsa khungu, kusalaza khungu, ndi kuteteza khungu lophwanyika.Ndi chithandizo chabwino cholowera kunja.

Njira Yochotsera:

Panopa Betulin analandira makamaka kudzera m'zigawo mwachindunji, ndipo makamaka ndi zosungunulira reflux m'zigawo ndi recrystallization kuyeretsa Makamaka: 1. Tingafinye betulin Mowa njira.Pambuyo Kutentha reflux za 5h, Tingafinye ndi zingalowe distillized ndi recrystallized ndi Mowa kwa 2 mpaka 3 nthawi ndi Mowa kupeza yaiwisi mankhwala betulin.2. Zopangira zopanda pake zidapangidwanso kuchokera ku methanol / chloroform (1: 1) (chilichonse cha 80g chosakanizidwa chimafuna 300mL methanol / chloroform solution) .Kusakaniza kumaloledwa kuyima usiku wonse ndikusefedwa kuti mupeze betulin yoyera ngati singano.3. Akupanga mankhwala kwa 20min pamene refluxing ikuchitika, ndi m'zigawo zokolola ndi mankhwala chiyero cha betulin akhoza bwino mwa chiwonongeko cha khungwa bungwe.4. Mikhalidwe yabwino kwambiri ya kutulutsa kwamadzimadzi a CO2 ndi motere: kuchuluka kwa kusintha kunali 115mL / (g birch bark ufa);kuthamanga m'zigawo ndi 20MPa;m'zigawo kutentha anali 55 ℃;madzi otaya CO2 anali 10kg/h.
