Abstract

Vitamin A (VA) is composed of various unsaturated organic compounds, such as retinol, retinal, and retinoic acid, along with several provitamin A carotenoids, with β-carotene being the most significant. This nutrient is essential for a broad spectrum of physiological functions in the human body. Various methodologies have been established to measure VA concentrations in diverse samples. Flow injection analysis (FIA) provides multiple advantages, including versatility, precision, cost efficiency, rapidity, and easy automation. This article aims to emphasize the significance and sources of VA, while also describing different chemiluminescence (CL) systems in use based on both direct and indirect CL in conjunction with the FIA system. Furthermore, it discusses FIA assays for the quantification of VA utilizing CL and spectrophotometric detection. A summarized table outlining the analytical characteristics of various techniques employed for VA analysis is also presented.

流动注射、化学发光和分光光度法测定维生素A的综述
维生素A (VA)由多种不饱和有机化合物组成,如视黄醇、视网膜和视黄酸,以及几种维生素A原类胡萝卜素,其中β-胡萝卜素是最重要的。这种营养物质对人体广泛的生理功能是必不可少的。已经建立了各种方法来测量不同样品中的VA浓度。流动注射分析(FIA)具有多种优点,包括多功能性、精度、成本效益、快速和易于自动化。本文旨在强调VA的意义和来源,同时还描述了基于直接和间接CL与FIA系统结合的不同化学发光(CL)系统。此外,还讨论了利用CL和分光光度法测定VA的FIA测定法。还提出了一个概述了用于VA分析的各种技术的分析特征的总结表。
