Katundu

Izi ndi zoyera mpaka zoyera za crystalline ufa, zopanda fungo.Kusungunuka m'magawo 1000 amadzi, magawo atatu a ether kapena magawo 2000 amafuta a mtedza.

Zofotokozera

Tsatirani mfundo za dziko GB3263-82 ndi British Pharmacopoeia 2013 edition, US Pharmacopoeia 34th edition, chemical reagent standard, American chakudya FCC-IV muyezo.

Kugwiritsa ntchito

Propyl Gallate (Pharmaceutical giredi) itha kugwiritsidwa ntchito ngati mulingo wofotokozera zamankhwala kuti adziwe za analyte pakupanga mankhwala ndi zakumwa zamafuta ndi chromatography ndi spectrophotometry.Miyezo yachiwiri ya Pharmaceutical yogwiritsidwa ntchito pakuwongolera bwino, imapereka ma labotale a pharma ndi opanga njira yabwino komanso yotsika mtengo pokonzekera miyezo yogwirira ntchito m'nyumba.

Propyl gallate ndi mankhwala opangidwa ndi phenolic antioxidant (SPA) omwe amagwiritsidwa ntchito muzakudya kuti aletse kapena kuwongolera lipid oxidation.Ma SPA ndi otsika mtengo, amapezeka kwambiri komanso ochita bwino kwambiri poyerekeza ndi anzawo achilengedwe.

Kusungirako

Sungani mu chidebe chotsekedwa kutali ndi kuwala ndipo pewani kukhudzana ndi zitsulo.

Kulongedza

Zogulitsazo zimadzaza ndi ng'oma za makatoni (￠ 360 × 500) zolemera zokwana 25 kg pa mbiya.
