Analysis of Functional Components of the Perilla Leaves (Perilla frutescens var. japonica Hara) Grown in Organic and Conventional Conditions

Abstract

The contents of functional components in the organically agricultural perilla leaves were compared with the perilla leaves grown in conventional condition. Perilla leaves used in the experiment were purchased or harvested from each three organic farm houses and conventional farm houses in Miryang city. The analyzed components included total phenol, total flavonoid, vitamin C, vitamin E, β-carotene, GABA, caffeic acid, rosmarinic acid, Total N, Zn, Fe, Ca, Mg, Na, K, and P. Organically grown perilla leaves had vitamin E 49% greater than the conventional perilla leaves, and 21% for TN, 29% for Ca, and 73% for Mg, while conventionally grown perilla leaves contained K 16% higher than organic ones. Other components were not showed the differences.
