Objectives : Elastic fibers are found in the skin, lungs, arteries, veins and other structures. Elastases destroy the elastic fibers and cause the emphysema and pulmonary hypertension. Oxidative stress is needed for these pathologic changes. Accordingly, present study was designed to investigate the effect of Yukmigeehwang-hwan extracts (YHE) on elastase activity and anti-oxidative effects of YHE. Methods : The inhibitory effects on elastase and DPPH and NO free radical scavenging activities of YHE were measured. Results : The elastase activity was significantly inhibited by YHE. YHE significantly scavenged DPPH and NO free radicals as well. Conclusion : YHE showed the elastase-inhibiting effects and anti-oxidative activities in vitro. These results suggest that YHE may have potential roles in the treatment of pulmonary emphysema and pulmonary hypertension.

본 연구에서는 생리활성물질유도제인 elicitor를 처리한 주름조개풀의 열수, 에탄올 추출물들의 항산화 효과, tyrosinase, elastase, collagenase 및 HAase 등의 미용관련 생리활성의 변화를 살펴보았다. Elicitor 처리한 주름조개풀 추출물의 DPPH 및 PF 등의 항산화 효과는 elicitor 비처리구인 대조구에 비해 elicitor 처리구가 농도의존적으로 더 높은 항산화 활성을 나타내었다. Elicitor 처리한 주름조개풀 추출물의 미용활성은 elastase 및 collagenase 억제 효과에 의한 주름개선효과와 tyrosinase 저해에 의한 미백효과가 비처리구인 대조구에 비해 상대적으로 매우 높은 효소 억제 효과를 나타내어 elicitor 처리가 주름조개풀추출물의 미백 및 주름개선 효과의 증대에 크게 영향을 미치는 것으로 확인되었으며, 농도의존적인 양상을 나타내었다. 또한 HAase 억제에 의해 유래되는 염증 억제 효과도 비처리구인 대조구에 비해 에탄올 추출물에서 우수한 염증 억제 효과를 나타내었다. Elicitor 처리에 의해 대조구에 비해 처리구에서 생리활성 효소에 대한 억제율이 큰 폭으로 상승하는 효과를 나타내어, elicitor 처리가 유용물질의 산업화라는 전제를 충족시키기 위한 biomass 기법으로 매우 적당하다는 것을 시사해주었다. 따라서 주름조개풀 노지재배 시에 본 연구에서 사용한 elicitor를 처리하면 수확되는 주름조개풀의 단위 무게 당 유용물질의 생산량을 높일 수 있고, 생리할성도 증대시킬 수가 있어 산업화를 위한 고기능성 원료생산에 효율적인 재배기법으로 활용할 수 있을 것이라 판단되었다.

배경: 약용식물 속새 풀에서 항산화물질의 존재는 확인되지 않았다. 목적: 본 연구는 속새 풀의 추출물의 항산화와 elastase inhibition 효과를 조사하는 것이었다. 방법: 속새의 줄기와 뿌리 부분을 채집하여 열수(HW) 및 에틸알코올(70EOH, 100EOH)로 추출한 물질들의 항산화 기능을 측정하였다. 결과: 줄기의 추출 수율은 HW추출에서 에틸알코올 추출보다 높았다. 폴리페놀 함유량은 줄기보다 뿌리 추출물에서는 유의하게 높았다. 70EOH 추출물의 총 플라보노이드 함량은 줄기 보다는 뿌리 추출물에서 유의하게 높았다. 뿌리 추출액의 elastase 저해 기능은 추출액 100 ppm에서는 46%의 효과가 있었고, 줄기에서는 49%의 효과가 있었다. ABTS 유리기 소거 기능 순서는 추출액 50 ppm 농도에서는 HW<70EOH<100EOH< 비타민E(99.7%)의 비율로 제거되었다. DPPH 유리기 소거능의 순서는 추출물 농도가 100 ppm일 때에 HW<100EOH<70EOH<비타민E(96.2%)로 나타났다. 양성 대조군인 비타민E의 제거율은 다른 추출물보다도 신속하고도 높게 진행되었다. 결론: 속새 풀 추출물에는 다량의 항산화물질이 존재하며 엘라스타제 저해 기능 효과도 높게 나타났다. 그런고로 속새 풀은 중요한 기능성 식물 중의 하나라고 판단한다.

In the previous study, we reported the antioxidative activity and inhibition of melanogenesis of Ligularia stenocephala extracts. In this study, inhibitory effect on elastase and production type I procollagen were investigated. The compounds which was investigated were 4-hydroxyacetophenone, vanillin, chlorogenic acid, caffeic acid isolated from Ligularia stenocephala. They were slightly mild on elastase inhibition activity but 4-hydroxyacetophenone, vanillin exhibited good inhibition activity on collagen production. These results suggest that Ligularia stenocephala may have potential as an anti-aging ingredient in cosmetics.

In this study, the anti oxidative effects, inhibitory effects on elastase, and components of Securinega suffruticosa extracts were investigated. The free radical (1,1-diphenyl-2-picrylhydrazyl, DPPH) scavenging activities ($FSC_{50}$) and reactive oxygen species ROS) scavenging activities ($OSC_{50}$) of extract/fractions from Securinega suffruticosa were measured. The aglycone fraction ($9.04\;{\pm}\;0.51\;{\mu}g/mL$) and 50 % ethanol extract ($1.05\;{\pm}\;0.41\;{\mu}g/mL$) showed the most effective scavenging activities. The protective effects on the rose-bengal sensitized photohemolysis of human erythrocytes were investigated. The aglycone fraction exhibited the most prominent cellular protective effect (${\tau}_{50},\;102.77\;{\pm}\;5.37$ min at $10{\mu}g/mL$). The inhibitory effect of ethyl acetate fraction on tyrosinase were of examined ($210.0\;{\pm}\;1.02\;{\mu}g/mL$). The inhibitory effect of aglycone fraction on elastase were also investigated ($17.6\;{\pm}\;1.26\;{\mu}g/mL$). These results indicate that extract/fractions of Securinega suffruticosa can function as antioxidants in biological systems, particularly skin exposed to UV radiation by scavenging $^1O_2$ and other ROS, and protect cellular membranes against ROS. Securinega suffruticosa extract could be used as a new cosmeceutical ingredient for whitening and anti-wrinkle products.
