Abstract

Gastrodia elata has a very low pollination rate in natural state, and even in artificial cultivation, there are very few individuals that bloom due to the degeneration, so little studies have been conducted. This study confirmed that the potential as a cosmetic ingredient by evaluating the antioxidant activity through the evaluation of DPPH radical scavenging activity, anti-inflammatory activity through the inhibitory effect on nitric oxide production, and the moisturizing activity through the effect on promoting hyaluronic acid production by artificially flowering G. elata flower. It was also confirmed that the appearance rate and flowering rate of G. elata harvested in spring were high, and the content of gastrodin was 0.36%. The IC50 value of G. elata flower extract was 0.045% and it was confirmed that G. elata flower extract had higher radical scavenging activity than G. elata root extract. The NO production inhibitory activity against the flower extract showed a significant inhibitory effect from 1% to 83.2%. Hyaluronic acid production promotion efficacy was not confirmed in the G. elata root extract, but the production rate increased with concentration dependence in the flower extract, and it was the highest at 46.9% when 0.02% treatment was performed. Based on the above research results, it is judged that G. elata flower extract has high potential for use as an antioxidant, anti-inflammatory, and skin moisturizing cosmetic ingredient.

천마(Gastrodia elata, G. elata)는 자연상태에서 수분율이 매우 떨어지고 인공재배에서도 자마의 퇴화로 꽃을 피는 개체가 드물어 연구가 거의 이루어지지 못하고 있다. 따라서 본 연구는 천마꽃을 인공개화시켜, DPPH radical 소거 활성 평가를 통한 항산화 효능, nitric oxide (NO) 생성 억제 효과를 통한 항염증 효과, hyaluronic acid 생성 촉진 효능을 통한 보습 효과를 평가하여 화장품 소재로서의 가능성을 확인하고자 하였다. 봄에 수확한 천마가 출현율과 개화율이 높게 나타났고 gastrodin은 0.36% 함유함을 확인하였다. 천마꽃 추출물의 DPPH radical 소거 활성에서 IC50 값은 0.045%로 나타났으며, 천마꽃 추출물이 천마뿌리 추출물에 비해 radical 소거능이 더 높음을 확인하였다. 천마꽃 추출물에 대한 NO 생성 억제 활성은 1%에서 83.2%로 유의적인 억제 효과를 나타내었다. Hyaluronic acid 생성 촉진 효능은 천마뿌리 추출물에서는 확인되지 않았으나, 꽃 추출물에서는 농도의존적으로 생성율이 증가하였으며, 0.02% 처리시 46.9%로 가장 높게 나타났다. 이상의 연구 결과를 바탕으로 천마꽃 추출물이 항산화, 항염, 피부 보습 화장품 소재로써 활용 가능성이 높을 것으로 판단된다.
