The present study investigated the quality characteristics of Perilla frutescens Britt. seed compounds according to the cultivar and sowing dates. In the present experiment, five Perilla cultivars, namely ‘Dayu’, ‘Deulsaem’, ‘Deulhyang’, ‘Baekjin’, ‘Sodam’, were planted on three different dates, including May 30, June 20, and July 10. The contents of key compounds and phenols varied depending on the cultivar and sowing date. With the delayed sowing time, the days to flowering and maturity of the culitvar decreased, while the seed weight and hardness increased. Crude protein content increased but crude lipid content decreased with the delay in the sowing time. However, there was no interaction of different sowing dates with the fatty acid content, which remained stable compared with the other values. Overall, the total polyphenol content was higher in Perilla seeds sown on May 30.
