Twenty components extracted from the essential oil in the leaves of 172 samples of Perilla frutescens var. crispa (vegetable crop form), P. frutescens var. frutescens (oil crop form), the wild/weedy form of P. frutescens, and three wild Perilla species, Perilla citriodora, Perilla hirtella and Perilla setoyensis were analyzed using GC/MS. A wide range of essential oil components were found among the wild/weedy form of P. frutescens, whereas distinctive components were detected in each wild Perilla species. Egomaketone, asaron, methyleugenol and 4,6-dimethoxy- or 4,7-dimethoxy-5-(2-propenyl)-1,3-dioxaindan were detected from Perilla for the first time. Limonene derivatives, piperitone and piperitenone, were detected from P. citriodora. Discovery of the limonene derivatives in this Perilla species provides evidence of this wild species being a genome donor of P. frutescens, while limonene synthase has been considered to be a specific enzyme in cultivated P. frutescens. These results will be useful for the evaluation and utilization of Perilla genetic resources.
