The objectives of this present study were to compare the contents and determine optimum extraction conditions for the rosmarinic acid (RA) and caffeic acid (CA) from leaves of Korean Perilla frutescens varieties. RA and CA from leaves of cv. Bora, a breeding line of P. frutescens were isolated and elucidated using various spectroscopic data. On the basis of 2 phenolic acids, optimum extraction conditions were obtained by employing 50% EtOH for 60 min at 25℃. We reported for the first time on the contents of RA and CA from leaves of 32 Korean varieties. Among them, leaves of P. frutescens Brit. var. acuta Kudo I exhibited the highest RA content (8.53±0.57 ㎎/g) and CA content (2.33±0.11 ㎎/g) showed the highest in the P. frutescens Brit. var. viridis Makino. Interestingly, average RA content (2.66±0.17 ㎎/g) showed a markedly higher than that of CA (1.98±0.16 ㎎/g) in Korean varieties. These results suggest that concentrations of the RA and CA in P. frutescens leaves could be a key factor in the selection process of a high quality species.
