Abstract

We found the conditions for the micellar extraction of active components from spices using 0.1 M Brij® 35 as an extractant and intensifying the process with ultrasonic treatment. A single extraction for 10 min ensures the maximum recovery of active components. The raw material-to-extractant ratio varies widely depending on the type of the spice. To characterize the extracts obtained, the Ce(IV)-based reducing capacity was used, based on the interaction of the extract components with electrogenerated Ce(IV). Using ascorbic acid as an example, we proved that the Brij® 35 micellar medium does not affect the current efficiency of the coulometric titrant. Stoichiometric coefficients of several biologically active compounds with electrogenerated Ce(IV) were determined. The Ce(IV)-based reducing capacity of 20 spices was determined. The results were compared with total antioxidant parameters.

香料中活性成分的胶束提取和基于 Ce(IV) 的提取物还原能力的评估

摘要

我们找到了使用 0.1 M Brij ® 35 作为提取剂并通过超声波处理强化该过程从香料中胶束提取活性成分的条件。单次提取 10 分钟可确保最大程度地回收活性成分。原料与提取剂的比例因香料的类型而异。为了表征获得的提取物,基于提取物组分与电生成的 Ce(IV) 的相互作用,使用了基于 Ce(IV) 的还原能力。以抗坏血酸为例,我们证明了 Brij ®35 胶束介质不影响库仑滴定剂的电流效率。确定了几种具有电生成 Ce(IV) 的生物活性化合物的化学计量系数。确定了 20 种香料的基于 Ce(IV) 的还原能力。将结果与总抗氧化参数进行比较。
