Betulin (CAS: 473-98-3) o se faʻamatalaga mai le paʻu o le laau paʻepaʻe birch, lea na lauiloa talu mai le 18th seneturi ma o loʻo faʻamalamalamaina i kemikolo.Betulin na maua e Siamani-Rusia kemisi Johann Tobias Lowitz.O ia o le saienitisi muamua na suʻesuʻe ma faʻamaonia le betulin, ma o le faia o se tasi lea o tagata muamua na faʻaesea se mea o loʻo galue malosi.O le Betulin o se mea e maua mai i la'au mama e maua ai le pa'u birch lona lanu pa'epa'e masani.E puipuia e Betulin la'au birch mai a'afiaga o le si'osi'omaga, e pei o le vevela tele, fa'ama'i fa'ama'i ma fa'avevela o le la.
Betulin o le pa'epa'e tioata pa'epa'e, solu i le ava malosi, chloroform ma benzene, soluble i le vai malulu, suau'u eter.
A'afiaga fa'aletino o le betulin
1. Betulin ma ana mea e maua mai ua fa'aalia le tele o le gafatia e avea ma sui olaola i le HIV ma le kanesa.Latou te galulue e ala i le faʻalavelave i laʻasaga mulimuli o le taamilosaga o le ola o siama ma e fesoʻotaʻi ma le ulufale mai o siama ma le tuputupu aʻe ma le matua.
2. O vailaʻau faʻamaʻi lelei, lea e mafua ai nisi ituaiga o sela tumo e amata ai polokalame apoptosis e faʻaleagaina ai le tagata lava ia, ma e mafai ona faʻagesegese le tuputupu aʻe o le tele o ituaiga o sela tuma.
3. Betulin e mafai ona faʻaitiitia ai le gaʻo e mafua mai i meaʻai, faʻaitiitia le lipid i totonu o le toto ma le tino, ma faʻaleleia atili le in-sulin k sensitivity.
4. O lo'o i ai a latou mea e fa'amama ai le fa'ama'i i le maualuga maualuga, ma o latou uiga fa'aanti-inflammatory e mafua ona o le fa'alavelaveina o auala e le o ni neural gene.
5. Betulin e mafai ona taofia le matua o le sterol regulatory element-binding proteins (SBERPs) i vivo, ma faʻaitiitia ai le biosynthesis o cholesterol ma gaʻo gaʻo.
6. E le gata i lea, o Betulin o loʻo i ai le anti-inflammatory, anti-viral, faʻalavelaveina le faʻamavaeina o le polotini i le alava o lauulu, faʻaleleia le susulu o lauulu faʻaleagaina, ma faʻalauteleina le tuputupu aʻe o lauulu.Betulin e mafai ona faʻaaogaina i meaʻai, mea teuteu ma falemaʻi.
Alamanuia tau vailaau:
Betulin e masani ona faʻaaogaina e avea o se vailaʻau faʻapitoa, ma Betulin ma ana mea e maua mai e avea o ni meaola olaola ua faʻaalia le malosi tele i togafitiga o le HIV ma le kanesa.I le taimi lava e tasi, e faʻaaogaina mo antitussive ma expectorant, togafitiga o le rhinitis allergic, le mautonu, atuatuvale, ma isi.
Alamanuia Taumafa:
O loʻo iai suʻesuʻega o loʻo faʻaaogaina e fai ma faʻasao i meaʻai a manu.
Alamanuia mea teuteu:
O le faʻalavelave faʻalavelave a Betulin i luga o le collagenase gaioiga ma le faʻateleina o sela paʻu o loʻo faʻaalia ai o loʻo i ai se malosi malosi e tetee atu ai i le matua ma e mafai ona faʻaaogaina e faʻaleleia ai le paʻu, faʻalelei le paʻu, ma puipuia le paʻu paʻu.Ose fesoasoani lelei fo'i tu'i i fafo.
I le taimi nei Betulin e maua tele e ala i tuusaʻo tuusao, ma e masani lava i solu reflux aveesea ma recrystallization faamamaina Faapitoa: 1. Aveese le betulin mai le vaifofo ethanol.A maeʻa le faʻamafanafanaina o le reflux pe a ma le 5h, o le mea faʻapipiʻi e faʻafefeteina ma faʻamalo i le ethanol mo le 2 i le 3 taimi i le ethanol e maua ai le oloa mama o le betulin.2. O le oloa mama sa recrystallized mai le methanol/chloroform (1: 1) (o oloa uma 80g crude manaomia 300mL methanol / chloroform solution). O le paluga e faatagaina e tu i le po ma suction faamamaina e maua ai le nila paʻepaʻe-pei o le betulin.3. Ultrasonic togafitiga mo le 20min pe a faʻataʻitaʻiina le refluxing, ma o le faʻaaogaina o le gaosiga ma le mama o oloa o le betulin e mafai ona faʻaleleia e ala i le faʻaleagaina o le faʻalapotopotoga o paʻu.4. O tulaga sili ona lelei o le su'eina o le sua o le CO2 sili ona taua e pei ona taua i lalo: o le aofa'i o le suiga o le 115mL/(g birch pa'u pa'u);o le mamafa o le aveeseina o le 20MPa;o le vevela o le aveeseina o le 55 ℃;vai CO2 fua faatatau tafe sa 10kg/h.
