Additionally, brown perilla seed contained greater contents of Ca, Mg, and P than those of white perilla seed (p<0.05). However, no difference in Fe content was found in both seeds (p>0.05). Brown perilla seed was rich in polyunsaturated fatty acid, in particular g-linolenic acid and a-linolenic acid. The most abundant of b-carotene and a-tocopherol was found in brown perilla seed. Higher total phenolic, total flavonoid, and total flavonol contents together with higher 2, 2-diphenyl-1-picrylhydrazyl (DPPH) and 2, 2’-azino-bis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS)-radical scavenging activities as well as a greater reducing capacity were observed in brown perilla seed extract (p<0.05). Therefore, brown perilla seed can be a good source of both macro- and micro-nutrients with phytochemical antioxidant activity.
