Abstract

This study was conducted to investigate the contents of dietary fiber (DF), compositions of fatty acids in lipid fraction and amino acids in salt-soluble protein from the functional food source such as Platycodi radix, perilla seed, evening primrose seed and aloe vera. The contents of dietary fiber, neutral detergent fiber (N.D.F) , acid detergent fiber( A.D.F) . kignin, hemicellulose an dcellulose in evening primorse seed were higher than those of other samples, except the content of cellulose .The ration of polyunsaturated /saturated (P/S) fatty acid in total lipids was 6.31 in perilla seed, which was higher than those of other samples. The content of linolenic acid (n-3) in perilla seed was 55.47%. The content of linoleic acid (n-6) in evening primrose seed was 71.88% , which was higher than those of other samples. The fatty acid composition in neutral lipids were the same as those of total lipids. The PUFA contents of fatty acid in glycolipids were 61.76% in perilla seed. And also, the ratio of n-6/n-3 in evening primrose seed was 15.19. The fatty acid compositions in phospholipids were the sameas those of glycolipids. The contents of PUFA in Platycodi radix were 62.96% . The essential amino acid contents of salt-soluble protein were 47 mole % in Platycodi radix , which was slightly higher than those other samples. The ration of essential amino acid /nonessential amino acid (E/N) was 0.9 and 0.66 in Platycodi radix and aloe vera, respectively.
