Abstract: This study was undertaken to determine and compare the nutritional compositions, phenolic components and antioxidant activities of seeds and pomace of Prinsepia utilis Royle. The results showed that the total phenolic and flavonoids contents of seeds were significantly higher than that of pomace. However, the contents of basic nutrient compositions were relatively higher in pomace. Seeds contained 12 free amino acids, while pomace contained 13 species. After hydrolysis, 17 amino acids were detected both in seeds and pomace. 14 fatty acids (mainly oleic acid and linoleic acid) and 7 minerals (mainly K and Ca) were found in seeds and pomace. 7 phenolic compounds in total (mainly narcissoside) were detected in both seeds and pomace. The results of antioxidant activities showed that the seeds and pomace had good abilities of scavenging free radicals, which were positively correlated with their total phenolic and flavonoids contents. This study demonstrated that the seeds and pomace of Prinsepia utilis Royle contain many nutrient substances and exhibit good antioxidant activities, which can provide a basis for the applications of Prinsepia utilis Royle in food and nutraceutical industries.
