Background : This study was carried out to investigate the possibility of cosmetics materials by comparing growth characteristics, photosynthetic rate and major functional components of Rosa multiflora and Perilla frutescens at different altitudes.
Methods and Results : This experiment is being carried out in April 2018 in Namwon (500 m above sea level) and Iksan (15 m above sea level) in Jeollabuk-do. The growth characteristics of R. multiflora were investigated at the end of May. Flowers were collected at this time and used as samples for functional analysis. The growth characteristics of P. frutescens were investigated in the middle of August and the ground part was collected at this time and used as a sample for functional analysis. Photosynthetic rates were measured using LCpro+ (ADC, UK). The marker compound were investigated and analyzed using HPLC Alliance e2695 and 2998 PDA detector (Waters, USA). Photosynthetic rate (based on 1,600 μ mole of light intensity) was measured in mid-June as follows. The R. multiflora showed 9.8 μ mole․CO2/㎡/s in Iksan and 7.9 μmole․CO2/㎡/s in Namwon. The P. frutescens showed 15.0 μmole․CO2/㎡/s in Iksan and 8.8 μmole․CO2/㎡/s in Namwon. Overall, Photosynthetic rate was higher in Iksan. As a result of analyzing 18 kinds of marker compound, gallic acid and astragalin were found in R. multiflora, caffeic acid and rosmarinic acid were found in P. frutescens. Gallic acid and Astragalin of R. multiflora showed 5.4 ㎎/g and 28.4 ㎎/g in Iksan and 3.2 ㎎/g and 21.6 ㎎/g in Namwon, respectively. Caffeic acid and rosmarinic acid of P. frutescens were 2.7 ㎎/g and 49.7 ㎎/g in Iksan and 2.5 ㎎/g and 33.6 ㎎/g in Namwon, respectively.
Conclusion : Comparing the yield of the harvesting parts by region, both R. multiflora and P. frutescens was higher in Namwon. As a result of quantitative analysis of four detected elements of gallic acid, astragalin, caffeic acid and rosmarinic acid, all four components were high in Iksan. It is considered that this is due to optical environment difference.
