Beauty food activities of wild-cultivated Ginseng (Panax ginseng C.A. Meyer) ground part

This study aimed to investigate the beauty food activities of wild-cultivated ginseng (Panax ginseng C.A. Meyer). wild-cultivated ginseng extracts were analyzed for antioxidant, skin whitening, anti-wrinkle effect was measured in water and 70% ethanol extract. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging and 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) radical decolorization activities of water and 70% ethanol extracts were 16.69 and 2.18% as well as 4.04 and 3.25% at a solid content of $200{\mu}g/mL$, respectively. The antioxidant protection factors (PF) of water and 70% ethanol extracts at a solid content of $200{\mu}g/mL$ were 1.06 PF and 1.09 PF, respectively. Thiobarbituric acid reactive substance (TBARs) were both 96% at a solid content of $200{\mu}g/mL$. As PF and TBARs showed higher activity than DPPH and ABTS, we could know that antioxidant activity in the lipophilic component of wood-cultivated ginseng were superior to water-soluble component of wood-cultivated ginseng. Tyrosinase inhibitory activity was 10.97 and 52.39% in water and 70% ethanol extracts at a solid content of $200{\mu}g/mL$. The collagenase and elastase inhibitory activities as anti-wrinkle effect were 15.71 and 20.43% in water extracts as well as 32.26 and 86.74% in 70% ethanol extract at a solid content of $200{\mu}g/mL$. The results show that anti-wrinkle effect was the best among the other experiments. This extracts from wood-cultivated ginseng, therefore, seems to be a potent beauty food resource against wrinkles.

산양삼(Panax ginseng C.A. Meyer) 지상부위의 미용 식품 활성

본 연구에서는 산양삼 지상부(줄기, 잎)의 동결건조물 함량을 달리하여 열수 추출물과 70% 에탄올 추출물을 제조하고, 항산화, 피부 미백 및 주름 개선 활성을 측정하여 미용 식품의 원료로 사용하기 위한 기초자료를 제공하고자 하였다. 산양삼 지상부열수, 에탄올 추출물은 $200{\mu}g/mL$ 농도에서 DPPH radical 저해율은 각각 16.69, 2.18%를 나타내었고, ABTS radical 저해율은 각각 4.04, 3.25%를 나타내었다. $200{\mu}g/mL$ 농도에서 열수 및 에탄올 추출물의 PF가 각각 1.06, 1.09 PF를 나타내었고, TBARs는 모두 96% 정도의 활성을 나타내었다. PF와 TBARs가 DPPH와 ABTS 보다 우수한 활성을 나타낸 것을 통하여 산양삼 지상부 추출물은 지용성 물질에 대한 항산화능이 더 뛰어나다는 것을 알 수 있었다. 열수 및 에탄올 추출물의 elastase와 collagenase 저해율은 $200{\mu}g/mL$ 농도에서 각각 15.71, 32.26% 그리고 20.43, 86.74%를 나타내었다. Tyrosinase 저해율은 $200{\mu}g/mL$의 농도에서 각각 10.97, 52.39%를 나타내었다. 이러한 결과에 따라 산양삼 지상부 추출물의 주름 개선 효과가 특히나 우수한 것을 알 수 있었으며, 피부의 주름을 개선시키는 새로운 미용 식품의 원료로서 사용이 가능할 것으로 기대된다.
