薄壳山核桃酚类代谢物研究进展

薄壳山核桃(Carya illinoensis)富含酚类代谢物,具有显著的抗氧化活性。近年来,我国薄壳山核桃产业快速发展,种植面积迅速扩大。明确薄壳山核桃中的酚类代谢物组成及保健功效对于促进健康产业发展具有重要意义。迄今为止,从薄壳山核桃中已检测出酚类代谢物67个,其中包括单宁36个、类黄酮22个、酚酸9个,水解后检测出酚类代谢物苷元34个。该文主要对薄壳山核桃酚类代谢物的组成、提取方法、含量、药理活性及与采后贮藏特性的关系进行综述,以期为今后深入研究薄壳山核桃酚类代谢物与其生理活性的关系及挖掘薄壳山核桃酚类代谢物的保健价值提供依据。

Recent Advances in Phenolic Metabolites in Pecan

Pecan (Carya illinoensis) is enriched in phenolic metabolites, which have significant antioxidant activity. In recent years, the pecan industry has developed rapidly in China, with drastic increase of planting area. It is of great significance to clarify the composition and health benefits of phenolic metabolites in pecan for promoting the healthy development of the industry. So far, a total of 67 phenolic metabolites have been detected from pecan, including 36 tannins, 22 flavonoids, and 9 phenolic acids. And 34 phenolic metabolite aglycones have been detected after hydrolysis. This paper summarizes the recent progresses in the composition, extraction method, content, pharmacological activity, and relationship with postharvest of phenolic metabolites in pecan. These data are of great significance to further study the relationship between the phenolic metabolites and their physiological activities, and explore the health benefits of the phenolic metabolites in pecan.
