[Dab tsi yog Huperzine A]

Huperzia yog hom moss uas loj hlob hauv Suav teb. Nws muaj feem xyuam rau cov qws mosses (Lycopodiaceae tsev neeg) thiab paub txog qee cov botanists li Lycopodium serratum . Tag nrho cov moss npaj tau siv ib txwm siv. Kev npaj tshuaj ntsuab niaj hnub tsuas yog siv cov alkaloid cais hu ua huperzine A. Huperzine A yog alkaloid pom nyob rau hauv huperzia uas tau tshaj tawm los tiv thaiv kev tawg ntawm acetylcholine, ib yam khoom tseem ceeb uas xav tau los ntawm lub paj hlwb kom xa cov ntaub ntawv ntawm tes mus rau ntawm tes. Kev tshawb fawb tsiaj tau pom tias huperzine A lub peev xwm khaws cia acetylcholine yuav ntau dua li ntawm qee cov tshuaj noj. Kev poob ntawm acetylcholine muaj nuj nqi yog qhov tseem ceeb ntawm ntau yam kev ua haujlwm ntawm lub paj hlwb, suav nrog Alzheimer's disease. Huperzine A kuj tseem tuaj yeem muaj kev tiv thaiv ntawm cov ntaub so ntswg hauv hlwb, ntxiv dag zog rau nws txoj kev muaj peev xwm los pab txo cov tsos mob ntawm qee lub hlwb.

[Function] Siv lwm cov tshuaj, huperzine A tau pom tias ua raws li cholinesterase inhibitor, ib hom tshuaj siv los tiv thaiv kev tawg ntawm acetylcholine (ib yam tshuaj tseem ceeb rau kev kawm thiab kev nco).

Tsis tsuas yog siv los ua kev kho mob Alzheimer's disease, huperzine A kuj tau hais los txhim kho kev kawm thiab kev nco thiab tiv thaiv lub hnub nyoog txog kev paub txog kev poob qis.

Tsis tas li ntawd, huperzine A qee zaum siv los txhawb lub zog, nce kev ceeb toom, thiab pab kho myasthenia gravis (ib qho kab mob autoimmune uas cuam tshuam rau cov leeg).

Nyob zoo cov txiv neej, hnub no kuv tau npaj ib daim vis dis aus txog kev tshem tawm yooj yim heev uas yog hais cov hmoov txhuv nplej siab los ntawm kev ua noj qos yaj ywm thiab nws cov txheeb ze kuaj nrog kev lag luam tincture ntawm iodine. Ua ntej pib tsuas yog ob lo lus hais txog cov hmoov txhuv nplej siab. Nws yog ib qho ntuj polymer tam sim no nyob rau hauv mov, cereal, qos yaj ywm thiab nws yog ib qhov chaw ntawm lub zog rau creatures nyob.
Nws yog tsim los ntawm ob hom polymers: amylose 20% thiab amilopecten 80%. Ob leeg ntawm lawv yog chains tsim los ntawm kev sib koom ua ke ntawm alpha qabzib. Ntawm no peb tuaj yeem pom cov duab yooj yim ntawm cov hmoov txhuv nplej siab uas yog ntau txoj hauv kev.
Tam sim no cia peb pib. Cov txheej txheem no yooj yim heev uas tus menyuam tuaj yeem ua tau yam tsis muaj teeb meem. Tsuas yog noj ib puas grams qos yaj ywm thiab tev nws. Tam sim no yooj yim grate nws. Thaum nws ua tiav, muab tso rau hauv lub lauj kaub nrog ob puas millimeters dej kub. Tam sim no sib tov rau li ib-ob feeb. Tom qab ntawd lim nrog lub tshuab ua noj rau lwm lub thawv. Nrog rau qhov kawg uas yog hais tias cov qos yaj ywm grated koj tuaj yeem rov ua haujlwm ob peb zaug ntxiv dej thiab sib tov, thiab lim dua, tab sis qhov no yog xaiv tau. Tom qab 5-10 feeb starch, insoluble rau hauv dej yuav precipitate tawm. Ntawm no peb tuaj yeem pom cov hmoov av dawb, cov hmoov txhuv nplej siab ntshiab. Tsuas yog txav cov kua theem mus rau lwm lub beaker koj yuav cais cov khoom. Cia nws qhuav ntawm chav tsev kub. Ntawm no peb tuaj yeem pom cov hmoov txhuv nplej siab thiab nws zoo li dawb, me ntsis creamy tab sis tom qab essiccation nws yuav cristalline.
Tam sim no, txhawm rau kuaj nws yog cov hmoov txhuv nplej siab tiag tiag thiab tsis yog hmoov hmoov, peb yuav siv qee qhov tincture ntawm iodine (ib qho sib xyaw ntawm ethanol, dej, potassium iodide thiab elemental iodine). Txhawm rau kuaj nws muab qee cov hmoov txhuv nplej siab tso rau hauv lub raj sim nrog dej thiab co. Tom qab ntxiv cov tincture ntawm iodine uas koj tuaj yeem diluite nrog dej los yog tsis. Txawm li cas los xij, cov tshuaj yuav dhau los ua xim xiav tsaus. Yuav ua li cas tshwm sim yog tias iodine ions (I3-) ua ke rau amilose thiab lawv ua kom cov compound coj li cov xim no.
Kuv txais tos, ntsib koj ntawm qhov kev sim tom ntej.
