ʻO Betulin (CAS: 473-98-3) kahi ʻili mai ka ʻili o ka lāʻau birch keʻokeʻo, i ʻike ʻia mai ke kenekulia 18 a ua wehewehe ʻia ma ke ʻano kemika.Ua ʻike ʻia ʻo Betulin e ka loea Kelemania-Russian Johann Tobias Lowitz.ʻO ia ka mea ʻepekema mua i aʻo a ʻike i ke ʻano o ka betulin, a ma ka hana ʻana ʻo ia kekahi o nā mea mua i hoʻokaʻawale i kahi mea kanu ikaika.ʻO Betulin kahi mea kanu maʻemaʻe e hāʻawi i ka ʻili birch i kona waihoʻoluʻu keʻokeʻo maʻamau.Mālama ʻo Betulin i nā lāʻau birch mai nā hopena o ke kaiapuni, e like me ka wela wela, nā mea ʻeha a me ka radiation lā.
ʻO Betulin ka pauka crystalline keʻokeʻo, hiki ke hoʻoheheʻe ʻia i ka waiʻona, chloroform a me benzene, hiki ke hoʻoheheʻe iki ʻia i ka wai anuanu, petroleum ether.
Nā hopena kino o ka betulin
1. Ua hōʻike ʻia ʻo Betulin a me kāna mau mea i loaʻa i ka mana nui ma ke ʻano he mau mea olaola i ka maʻi HIV a me ka mālama ʻana i ka maʻi kanesa.Hana lākou ma ka hoʻopili ʻana i nā pae hope o ka pōʻaiapuni ola a pili i ka hoʻokomo ʻana i ka maʻi virus a me ka ulu ʻana a me ka oʻo.
2. ʻO nā lāʻau lapaʻau kūʻokoʻa maikaʻi, ka mea e hoʻomaka ai i kekahi mau ʻano o nā pūnaewele tumora e hoʻomaka i nā polokalamu apoptosis hoʻopau iā ia iho, a hiki ke hoʻolohi i ka ulu ʻana o kekahi mau ʻano o nā ʻano maʻi tumora.
3. Hiki i ka Betulin ke hoʻohaʻahaʻa i ka momona i hoʻokomo ʻia i ka meaʻai, hoʻemi i ka ʻike lipid i loko o ka serum a me ka ʻiʻo, a hoʻomaikaʻi i ka ʻike in-sulin k.
4. Loaʻa iā lākou nā waiwai anti-inflammatory maʻalahi ma nā ʻano kiʻekiʻe, a ʻo kā lākou mau mea anti-inflammatory ma muli o ka pale ʻana i nā alahele gene non-neural.
5. Hiki i ka Betulin ke kaohi i ka oo ana o ka sterol regulatory element-binding proteins (SBERPs) in vivo, pela e hoemi ai i ka biosynthesis o ka cholesterol a me ka momona.
6. Eia kekahi, he anti-inflammatory, anti-viral, inhibiting protein dissolution i loko o ka lauoho lauoho Betulin, hoʻomaikaʻi i ka luster o ka lauoho i hōʻino ʻia, a hoʻoikaika i ka ulu ʻana o ka lauoho.Hiki ke hoʻohana ʻia ʻo Betulin i nā meaʻai, nā mea hoʻonaninani a me nā ʻoihana lāʻau lapaʻau.
ʻoihana lāʻau lapaʻau:
Hoʻohana nui ʻia ʻo Betulin ma ke ʻano he lāʻau lapaʻau, a ua hōʻike ʻo Betulin a me kāna mau derivatives e like me nā mea olaola i ka mana nui i ka mālama ʻana i ka maʻi HIV a me ka maʻi kanesa.I ka manawa like, hoʻohana ʻia ia no ka antitussive a me ka expectorant, ka mālama ʻana i ka rhinitis allergic, insomnia, depression, etc.
ʻOihana meaʻai:
Aia nā haʻawina e hoʻohana ana ia mea ma ke ʻano he preservative i nā huahana ʻiʻo.
ʻoihana hoʻonaninani:
ʻO ka hopena pale o Betulin i ka hana collagenase a me ka hoʻonui ʻana o nā ʻili o ka ʻili e hōʻike ana he hopena anti-kahiko ikaika a hiki ke hoʻohana ʻia e hoʻomaʻamaʻa i ka ʻili, hoʻomaʻamaʻa i ka ʻili, a pale i ka ʻili chapped.He kōkua maikaʻi hoʻi ia e komo i waho.

Keʻano unuhi:

I kēia manawa loaʻa ʻia ʻo Betulin ma o ka unuhi pololei ʻana, a ʻo ka mea nui ma o ka solvent reflux extraction a me ka hoʻomaʻemaʻe recrystallization kikoʻī: 1. E unuhi i ka betulin mai ka hopena ethanol.Ma hope o ka hoʻomehana ʻana i ka reflux ma kahi o 5h, ua hoʻoheheʻe ʻia ka extract me ka ethanol no 2 a 3 mau manawa me ka ethanol no ka loaʻa ʻana o ka hua o ka betulin.2. Ua hana hou ʻia ka huahana mai ka methanol/chloroform (1: 1) (e pono i kēlā me kēia 80g o nā huahana ʻōpala he 300mL methanol/chloroform solution).3. Ultrasonic lapaʻau no 20min i ka refluxing hana, a hiki ke hoʻomaikaʻi i ka hoʻoulu ʻana a me ka maʻemaʻe huahana o betulin ma o ka luku ʻana i ka hui ʻili.4. ʻO nā kūlana maikaʻi loa o ka hoʻoheheʻe ʻana i ka wai CO2 supercritical penei: ʻo ka nui o ka mea hoʻololi ʻo 115mL/(g birch bark pauka);ʻO 20MPa ke kaumaha o ka unuhi;ʻO 55 ℃ ka wela o ka lawe ʻana;wai CO2 kahe kahe he 10kg / h.
