Puas yog Peanut Skin Adulterating Koj Grape Seed Extract?

 

Kev Tshawb Fawb Txog Kev Tshawb Fawb Txog Oligomeric Proanthocyanidins thiab Polymerization Kev dag ntxias los ntawm Xi'an Tihealth

Oligomeric Proanthocyanidins (OPC) yog cov khoom tseem ceeb tshaj plaws rau cov hlab plawv elasticity thiab endothelial nitric oxide qhia. Ntiaj teb no los tiv thaiv- kev laus thiab vascular noj qab haus huv hom lag luam wholesale grape noob extract nyob rau hauv loj ntim. Tab sis kev ua lag luam khoom lag luam tau poob qis heev. Cov neeg saib xyuas kev yuav khoom ntsuas cov hmoov ntau uas siv pheej yig, tsis yog - cov kev kuaj xim tshwj xeeb. Lawv yuav raws li cov ntaub ntawv raw "95% Proanthocyanidins" thov.

Daim ntawv pov thawj ntawm kev tsom xam yog ib qho illusion. Rogue extract factories txiav cov txiv hmab txiv ntoo uas pheej yig ua liaj ua teb pov tseg: ** Peanut Skin Extract ** . Qhov kev ntsuam xyuas lub hauv paus sau npe zoo rau proanthocyanidins, tab sis tus nqi lom neeg tsis muaj -. NtawmXi'an Tihealth Biotechnology Co., Ltd., peb ua haujlwm raws li kev nruj ISO9001: 2015 zoo voj. Peb rhuav tshem kev tsim txom nyiaj txiag los ntawm thiolysis degradation thiab loj spectrometry. Cia peb deconstruct lub stereochemistry ntawm polymerization kev dag ntxias.

Yuav Ua Li Cas Cov Neeg Siv Khoom Siv Tus Txheej Txheem Porter los npog Peanut Skin Adulteration?

Cov khoom lag luam kev dag ntxias yog nyob ntawm qhov kev ntsuas qhov tsis zoo. Kev tswj hwm tus qauv zoo siv ** Tus Txheej Txheem Tus Txheej Txheem ** (Butanol-HCl kev soj ntsuam) txhawm rau txheeb xyuas tag nrho cov proanthocyanidins.

Kev kuaj Porter yog tshuaj tsis pom kev. Nws ua kom sov cov qauv hauv cov kua qaub kom tshem tawm cov ntawv cog lus interflavanoid, tsim cov xim liab anthocyanidin uas UV-Vis ​​spectrophotometer suav tias yog "purity." Cov tawv nqaij ntawm cov txiv laum huab xeeb yog ntim nrog cov tannins condensed uas ua rau tib yam rau cov noob txiv hmab hauv qab acid hydrolysis. UV meter flashes zoo meej 95% kev ntsuas.

Txawm li cas los xij, cov txiv laum huab xeeb qhia txog kev lav phib xaub loj: ** Hom -A Interflavan Bonds **. Cov txiv hmab txiv ntoo tiag tiag muaj hom kev sib txuas ncaj qha -B. Tsis tas li ntawd, cov txiv laum huab xeeb muaj cov khoom seem ntawm txiv laum huab xeeb (Ara h proteins). Formulating nrog nplooj -spiked los yog daim tawv nqaij- cov khib nyiab pov tseg qhia ua rau muaj kev phom sij hnyav rau koj cov neeg siv khoom thiab nthuav tawm koj lub hom phiaj rau kev rov qab los ntawm kev cai lij choj loj.

Normal-Phase HPLC Profile of Degree of Polymerization

Kev txheeb xyuas qhov tseeb: Ib txwm-theem kua chromatography ntiv tes cais tawm bioavailable qis-DP oligomers los ntawm cov macro tsis tuaj yeem-polymers.

Vim Li Cas Lub Degree ntawm Polymerization (DP) txiav txim siab muaj tseeb Bioavailability?

Proanthocyanidins yog cov saw hlau molecular. Tus naj npawb ntawm flavan-3-ol units nyob rau hauv cov saw dictates nws **Degree ntawm Polymerization (DP)**.

Tib neeg txoj hnyuv epithelium tsuas tuaj yeem nqus tau qis -DP feem. **Oligomers (DP 2 txog 4)** muaj solubility siab thiab ceev cellular thauj kinetics. Lawv yooj yim nkag mus rau hauv cov hlab ntsha kom tshem tawm cov dawb radicals thiab tiv thaiv cov hlab ntsha. **Polymers (DP> 5)** yog qhov loj, hnyav macro-tannins. Lawv tag nrho insoluble thiab unabsorbable. Lawv khi rau cov hnyuv proteins, ua rau muaj kev tsis txaus siab thiab mob plab.

Cov txiv laum huab xeeb ntawm daim tawv nqaij yog thawj coj los ntawm hnyav, tsis muaj txiaj ntsig polymers nrog DP tshaj 10. Cov neeg muag khoom pheej yig zais cov macro-polymers nyob rau hauv lawv qhov kev ntsuam xyuas tag nrho proanthocyanidin. Xi'an Tihealth re-engineers cov metrics extraction. Peb xa cov qib siab **Thiolysis Degradation ua ke nrog LC-MS/MS**. Peb rhuav cov chains los xam qhov tseeb Mean Degree of Polymerization (mDP). Peb lav qhov qis -mDP, oligomer-dominant API matrix haum rau kev soj ntsuam tam sim ntawd.

Puas tuaj yeem-Phase HPLC Definitively cais Grape Monomers Los ntawm Peanut Tannins?

Tus qauv thim rov qab-theem chromatography tsis cais cov polyphenols nyuaj. Lawv elute raws li ib leeg, ntxhov hump ntawm chromatogram. Qhov kev ntsuas tsis ua tiav no tso cai rau cov neeg dag ntxias kom vam meej.

Peb tswj hwm **Normal-Phase High-Performance Liquid Chromatography (NP-HPLC)**. NP-HPLC cais cov proanthocyanidins nruj me ntsis los ntawm lawv cov saw ntev. Monomers elute ua ntej, ua raws li huv si los ntawm dimers, trimers, thiab tetramers.

Cov ntaub ntawv yog kiag li. Peb NP-HPLC ntiv tes ua kom ntseeg tau tias cov ntsiab lus oligomeric (DP Tsawg dua los yog sib npaug rau 4) sawv cev rau feem ntau ntawm peb cov extract loj. Peb tshem tawm qhov tsis muaj txiaj ntsig, siab -molecular- hnyav polymeric dregs. Xi'an Tihealth muab cov khoom ua kom zoo, canary-xim av, ultra-soluble micro- hmoov uas yaj sai sai hauv cov kua nruab nrab yam tsis tsim cov sludge sediments.

Strategic Sourcing FAQ: Bulk Grape Seed OPC

Vim li cas 95% UV proanthocyanidins daim ntawv pov thawj tsis ua pov thawj zoo?
UV spectrophotometric tsis muaj qhov tshwj xeeb molecular. Nws tsim cov tshuaj tiv thaiv xim nrog ib qho condensed tannin molecule, txawm tias nws yog los ntawm siab -cov noob txiv hmab txiv ntoo, ntoo thuv tawv ntoo, lossis cov txiv laum huab xeeb pheej yig. Cov khoom siv raw khoom cuav tau yooj yim ua rau UV sensor. Tsuas yog huab hwm coj spectrometry thiab chromatography tuaj yeem cais cov tshuaj keeb kwm tshwj xeeb.
Hom-Ib daim ntawv cog lus interflavan yog dab tsi, thiab vim li cas lawv thiaj txaus ntshai?
Hom-Ib daim ntawv cog lus muaj kev sib txuas ntawm ob qho ntawm flavan-3-ol subunits, cov qauv ntawm cranberry thiab txiv laum huab xeeb daim tawv nqaij proanthocyanidins. Grape noob muaj ib qho nkaus xwb -linked Type-B bonds. Kev Tshawb Nrhiav Hom-A kev sib txuas ntawm huab hwm coj spectrometry hauv cov txiv hmab txiv ntoo loj batch yog ib qho pov thawj tseeb ntawm txawv teb chaws botanical adulteration.
Puas muaj peev xwm siab -OPC tuaj yeem muab tso rau hauv cov tshuaj pleev ib ce huv?
Yog lawm. High-purity oligomeric proanthocyanidins yog cov tshuaj pleev ib ce tshwj xeeb -linkers rau kev tiv thaiv collagen. Txawm li cas los xij, yog tias koj cov hmoov muaj cov khoom hnyav polymeric tannins los ntawm cov txiv laum huab xeeb, nws yuav ua rau tawv nqaij qhuav heev, kev ntxhib los mos, thiab xim daj (xim av) ntawm cov ntshav. Sourcing Tihealth's low-DP micronized micro- hmoov guarantees optical clarity thiab du daim tawv nqaij rheology.
Puas yog Xi'an Tihealth khiav hnyav hlau tshuaj ntsuam ntawm cov noob txiv hmab?
kiag li. Grape vineyards yog rhiab heev rau kev lag luam thiab kev ua liaj ua teb av paug. Txhua qhov kev rho tawm khiav ntawm Xi'an Tihealth tau kuaj xyuas los ntawm ICP-MS. Peb lav Lead (Pb), Cadmium (Cd), thiab Arsenic (Raws li) qib tau nruj me ntsis txwv zoo hauv qab cov cai nruj ntawm USP thiab California Proposition 65 monographs.
