摘要阿魏酸是植物界普遍存在的一种酚酸,在植物体内很少以游离态存在, 主要与低聚糖、多胺、脂类和多糖形成结合
态。它有许多保健功能,如清除自由基、抗血栓、抗菌消炎、抑制肿瘤、防治高血压、心脏病、增强精子活力等。阿魏酸毒性低,易于
为人体代谢,其用途越来越广泛。阿魏酸在食品工业中主要用于制备天然香兰素、抗氧化剂、防腐剂、交联剂和机能促进剂等,阿
魏酸可通过化学合成法和提取法获得。

Abstract Ferulic acid ,4 - ( - hydroxy - 3 - methoxyphenyl) - 2 - propenoic acid , an ponent of Chinese medicine herbs ,
such as Angelica sinensis , Cimicifuga heracleifolia and Lignsticum chuangxiong , is a ubiquitous phenolic acid in the plant kingdom. It is mainly
conjugated with mono - and harides , polyamines , lipids and harides and seldom occurs in a free state in plants. Ferulic acid is
a phenolic acid of low toxicity ; it can be absorbed and easily metabolized in the human body. It has many physiological functions , including an
tioxidant , antimicrobial , anti - inflammatory , anti - thrombosis , and anti - cancer activities , and also protects against coronary disease , lowers
cholesterol and increases sperm viability. Because of these properties and its low toxicity , ferulic acid is now widely used in the food industries.
It is used as the raw material for the production of vanillin and preservatives , as a cross - linking agent for the preparation of food gels and edible
films , and as an ingredient in sport foods. Ferulic acid ca
