  • The objective of this study is to estimate the inhibition of skin melanin formation by extract of Angelica koreana and Cnidium monnieri and the possibility of functional cosmetic materials through anti-irritation and stability test. The extract used in this experiment is White-$AK^{TM}$ and the INCI name is Osthole. The main component of White-$AK^{TM}$ was identified as coumarin and EC50 value was 2.7ppm by mouse melanoma B 16 cell test. White-$AK^{TM}$ showed inhibitory effects 100 times lower concentration than arbutin. The main mechanism for skin whitening effect thought to be inhibition of tyrosinase-related gene expression. The basic essence formulation of White-$AK^{TM}$ 5% solution applied to the skin showed the effect of relieving skin irritation. White-$AK^{TM}$ in an opaque container, under UV conditions for 4 weeks, and showed close to 100% recovery and 97% recovery under $50^{\circ}C$ for 4 weeks. Therefore, it is thought that White-$AK^{TM}$ which helps skin whitening, relieving skin irritation and stable in UV condition is able to be used as the functional component in the cosmetic formulation.

  • This study was conducted to investigate the soil mulching effect on bolting and growth of Angelica koreana Max. The bolting ratio were 8.4% of non-mulching, 11.4% of black polyethylene film, 13.6% of transparent polyethylene film, 6.4% of rice-straw mulching. The mulching of polyethylene film induced higher bolting response than other materials. The radical leaf length, the number of leaf and crown in black P.E. film mulched were all higher than those of non-mulching and rice-straw mulching. The yield of the underground part of P.E film mulching was higher than non-mulching and rice-straw mulching. Comparing with other treatments, the dry root yield of black P.E. film mulching showed the most.
