چکیده

A method is described that accurately and rapidly quantifies the free and total phosphorous content of a commercially available, purified, phytic acid preparation. This allows its use as a standard for phytic acid determinations in foods. The method involves a wet ashing step followed by phosphorous measurement with a 1-amino-2-naphthol-4-sulfonic acid-molybdate reagent in a microplate reader at 660 nm. The procedure can be performed in 3 h with as little as 50 mg sample.

Separation of phytic acid and other related inositol phosphates by high-performance ion chromatography and its applications.

A high-performance anion-exchange chromatographic method was developed for the separation of phytic acid and other inositol phosphates (myo-inositol bis-, tris-, tetrakis-, and pentakisphosphates) with gradient elution and ultraviolet absorbance detection after post-column derivatization. With the acidic eluents, the combination of anion-exchange and ion suppression retention mechanisms led to ...

تأثیر باکتریهای اسید لاکتیک جدا شده از خمیرترش بر اسید فیتیک

Background: Phytic acid is phosphated compound that exists as potassium - magnesium salt in aleurone layer of cereals. Phytic acid has a strong ability to chelate  many minerals, such as calcium, iron and zinc. It changes these essential minerals to insoluble complexes and inhibits minerals bioavailability. In this study, effect of several lactic acid bacteria (casei, fermentum, plantarum ...

Phytic Acid Mitigates Motor Asymmetry in Male Rat with Unilateral 6-Hydroxydopamine Striatal Lesion

Background and Objective: Parkinson's disease (PD) is a movement disorder with debilitating symptoms. Available treatments for PD mainly include its symptomatic relief with no prevention of its progression. Due to the iron-chelating and antioxidant effect of phytic acid (PA), this study was conducted to assess its protective effect in 6-hydroxydopamine-induced model of PD in rat. Materials and ...
