Studies on the Cosmeceutical Activities of Perilla frutescens var. acuta

Perilla frutescens var. acuta의 화장품 약리활성에 관한 연구

Objectives : This study aimed to establish cosmeceutical activities of Perilla frutescens var. acuta. Methods : Folium Perillae, which had been extracted, concentrated, and freeze drying with water and ethanol, have been used for the experiment. The effects on electronic donating ability, SOD-like activity, xanthine oxidase inhibition, whitening effect have been investigated in the cosmeceutical activity measurement of function experiment. Results : Both water and ethanol extracts of Perilla frutescens var. acuta showed relatively high electron donating ability of more than 70% at over 500ppm. Also, SOD like activity increased in a dose dependent matter of more than 80% at 5,000ppm, while tyrosinase showed insufficient inhibitory rate. Xanthine oxidase showed a meaningful inhibitory effect of 72.4% in water extract and 55.3% at 1,000ppm in ethanol extract. The addition of $Fe^{2+}ion\;and\;Cu^{2+}ion$ showed relatively high oxidizing inhibitory effect of 57% and 41%, respectively, at 500ppm in water extract and, when $Fe^{2+}$ ion was added in ethanol extract, the effect of 64% at 1,000ppm was achieved. Also, higher oxidizing inhibitory effect was shown against $Fe^{2+}$ rather than $Cu^{2+}$ in both water and ethanol extracts. For human cancer cells, relatively high growth inhibition ability was shown against melanoma G361 in both water and ethanol extracts. Conclusion : From the above results, it was confirmed that Perilla frutescens var. acuta could be used in functional cosmetics.
