|
We investigated antioxidant activity and lignan contents by harvesting times to expand use of Schisandra chinensis (Turcz.) Baillon. Total polyphenol and flavonoid contents of seed was higher than those of flesh but there is not much difference in harvesting times. As value, that was, the concentration of sample required for 50% reduction of 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical, was 13.7~24.2 in seed thus it showed a high antioxidant activity. Among lignan components, schizandrin content was the highest and followed by gomisin N and gomisin A in all of flesh and seed. Also these components in seed were 4~9 times more contained than those of flesh. All of them were decreased by harvesting times in flesh. But the contents of schizandrin and gomisin N were high in August 3rd and September 15th in seed, respectively. As the results, the seed of S. chinensis had high antioxidant activity and lignan contents so it could be potentially developed as a resource.
