Abstract: 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.
