Physical thiab Chemical Properties

1. Lub cev muaj zog

• Cov tsos mob thiab lub xeev

Pterostilbene feem ntau yog dawb crystalline hmoov.Pterostilbene bulk hmoovyog ib qho ruaj khov thaum khaws cia thiab thauj.

• Solubility

Nws muaj zoo solubility hauv cov kuab tshuaj organic. Piv txwv li, nws muaj peev xwm qhia tau zoo solubility hauv cawv solvents xws li ethanol thiab methanol. Nws tuaj yeem muab rho tawm tau zoo siv cov kuab tshuaj cawv hauv cov txheej txheem ntawm kev rho tawm thiab purifying pterostilbene. Txawm li cas los xij, nws cov solubility hauv dej yog qhov tsawg. Qhov no yog vim muaj coob tus ntawm hydrophobic pawg nyob rau hauv nws cov qauv molecular, ua rau nws nyuaj rau yaj nyob rau hauv ntau polar dej.

• Melting Point

Lub melting point yog li ntawm 89 - 92 degree . Nws yog ib qho tseem ceeb ntawm lub cev. Lub melting point yog ib qho tseem ceeb ntawm lub cev khoom ntawm ib yam khoom. Kev txiav txim siab ntawm nws cov ntsiab lus melting tuaj yeem pab txiav txim siab purity ntawm ntshiab pterostilbene hmoov. Cov qib siab ntawm impurities feem ntau ua rau muaj qhov dav dua lossis qis dua.

• tsw thiab saj

Bulk Pterostilbene yuav luag tsis muaj qhov tshwj xeeb tsw thiab muaj ib qho iab saj. Qhov no me ntsis tsw thiab saj kuj yuav pab tau rau qee qhov thaum nws los txog rau nws qhov kev txheeb xyuas. Qhov no tuaj yeem tshem tawm kev cuam tshuam los ntawm impurities uas muaj ntxhiab tsw lossis saj.

• Ceev

Nws qhov ceev yog ntau dua li cov dej, nyob ib ncig ntawm 1.25 g / cm³. Cov cuab yeej no muaj txiaj ntsig zoo hauv kev ua haujlwm cuam tshuam nrog kev sib cais thiab rho tawm ntawm astragalus. Piv txwv li, hauv qee qhov ceev gradient centrifugation lossis cov txheej txheem rho tawm, kev sib cais tuaj yeem ua tiav raws li qhov sib txawv ntawm nws qhov ceev thiab lwm yam kuab tshuaj los yog tshuaj.

 

2. Cov khoom siv tshuaj

• Kev ruaj ntseg

Nyob rau hauv chav tsev kub thiab siab, Pterostilbene kuj ruaj khov. Txawm li cas los xij, nws cov qauv tshuaj tuaj yeem hloov pauv nyob rau hauv cov xwm txheej ntawm lub teeb, kub siab lossis muaj cov tshuaj tiv thaiv oxidizing muaj zog. Piv txwv li, nyob rau lub caij ntuj sov raug tshav ntuj los yog kub kub, nws yuav raug oxidative cov tshuaj tiv thaiv, ua rau txo qis hauv nws cov antioxidant thiab lwm yam dej num.

• Redox Reactions

Trans Pterostilbene hmoov muaj qee yam antioxidant zog. Qhov no yog ib qho ntawm nws cov khoom tseem ceeb tshaj plaws tshuaj. Nws muaj phenolic hydroxyl pawg hauv nws cov qauv molecular. Nws muaj peev xwm tshem tawm cov dawb radicals hauv lub cev los ntawm kev muab hydrogen atoms los ua antioxidant. Thaum lub sij hawm cov tshuaj tiv thaiv nrog dawb radicals, phenolic hydroxyl pawg yog oxidised rau ib tug quinone qauv. Nyob rau tib lub sijhawm, cov qauv quinone tuaj yeem txo qis rov qab mus rau qhov qub phenolic hydroxyl qauv raws li qhov tsim nyog txo qis.

• Cov tshuaj tiv thaiv acid-base

phenolic hydroxyl pawg nyob rau hauv lub molecule ntawmpterostilbene bulk hmoovmuab nws ib qho acidity. Nyob rau hauv cov xwm txheej alkaline, cov hydrogen atoms ntawm pawg phenolic hydroxyl tuaj yeem hloov los ntawm alkali hlau ions los tsim cov ntsev sib xws. Cov cuab yeej acid-base reactivity no tseem muab lub hauv paus rau nws daim ntawv thov hauv kev hloov kho tshuaj thiab kev npaj tshuaj, thiab lwm yam. Piv txwv li, nws cov tshuaj chemical thiab reactivity tuaj yeem tswj tau los ntawm kev kho cov qib acid-puag.

 

Kev nyab xeeb

• Kev Nyab Xeeb Kev Nyab Xeeb

PterostilbeneTejHmoovsuav hais tias muaj kev nyab xeeb ntawm cov koob tshuaj ib txwm siv. Hauv ntau qhov kev tshawb fawb, Bulk Pterostilbene hmoov tsis tau pom tias ua rau mob hnyav rau tib neeg. Nws muaj qee qhov zoo sib xws rau resveratrol raws li cov qauv tshuaj thiab cov khoom. Resveratrol tau raug tshawb fawb ntau thiab pom tias muaj kev nyab xeeb rau qee qhov. Raws li cov txheej txheem zoo sib xws, Pterostilbene kuj tau pom tias muaj kev nyab xeeb zoo.

 

• Kev nyab xeeb ntawm daim tawv nqaij

Thaum siv cov khoom siv tawv nqaij, Pterostilbene muaj kev nyab xeeb rau cov tawv nqaij feem ntau. Nws tuaj yeem pab tiv thaiv daim tawv nqaij los ntawm kev puas tsuaj dawb radical, o, thiab UV rays. Txawm li cas los xij, rau qee cov neeg uas muaj tawv nqaij rhiab, tej zaum yuav muaj kev tsis haum tshuaj. Qhov no yog vim txhua tus neeg muaj qhov sib txawv ntawm daim tawv nqaij. Ib yam li qee tus neeg tsis haum rau paj ntoos thiab lwm tus tsis yog. Cov tawv nqaij khaus khaus thiab kev ua xua yog yuav tsum tau ua kom muaj kev nyab xeeb thaum ntxiv pterostilbene hmoov rau cov khoom tu tawv nqaij.

• Kev nyab xeeb ntawm qhov ncauj

Hais txog kev tswj hwm qhov ncauj, cov kev tshawb fawb tam sim no tau pom tias ntawm cov koob tshuaj uas tsim nyog Pterostilbene hmoov tsis muaj tshuaj lom tseem ceeb. Txawm li cas los xij, raws li nws yuav tau metabolized hauv lub cev nws txoj hauv kev metabolic thiab cov khoom yuav tsum tau kawm ntxiv. Yog tias noj ntau dhau ntawm qhov ncauj, nws tuaj yeem ua rau lub cev hnyav xws li lub siab thiab lub raum.
