This study attempted to investigate the physiological activities of Passiflora caerulea extract and provide basic data needed to verify its availability as an inner beauty material. To examine its anti-oxidant, anti-inflammatory and anti-aging effects, the followings were measured: total polyphenol contents, total flavonoid contents, DPPH radical scavenging activity, cytotoxicity and NO inhibition effects in RAW 264.7 macrophage cells and HDF cells and MMP-1 inhibitory effects in HDF cells. The results found the followings: First, polyphenol and flavonoid contents were great with 157 mg/g and 173.5 mg/g respectively at 10mg/mL, and DPPH radical scavenging activity was confirmed. In RAW 264.7 macrophage cells and HDF cells, no cytotoxicity was observed for Passiflora caerulea extract. In addition, 69.3% anti-inflammatory effects were found at 100 ㎍/mL through NO inhibition in RAW 264.7 macrophage cells. In addition, a significant inhibition of MMP-1 expression in HDF cell was confirmed. The above results confirmed the anti-oxidant and anti-inflammatory effects of Passiflora caerulea extract, low toxicity on skin cells and its anti-aging effects by inhibiting MMP-1 expression. Therefore, it appears that Passiflora caerulea extract would be available as diverse inner beauty materials.

패션프루트(Passiflora edulis)는 브라질이 원산지이며 아열대와 열대지역에서 재배되고 있는 다년생 상록덩굴식물로 시계꽃과(Passifloraceae) 시계꽃속(Passiflora)에 속한다. 전 세계적으로 500여종이 분포하고 그 중 10여종은 식용, 나머지는 관상용으로 이용되고 있다. 지구온난화로 인한 기온상승으로 전남지역 재배에 적합한 대체 아열대과수 개발이 필요하다. 패션프루트는 겨울 최저온도가 $3^{\circ}C$이상 조건에서 재배 가능하여 남부 지역는 무가온 하우스재배를 하고 있지만 시설내 6월 하순부터 8월 중순까지 $35^{\circ}C$ 이상 고온이 지속되어 과실을 볼 수 없다. 8월 하순부터 피는 꽃은 인공수분으로 착과되어 11월부터 수확이 가능하지만 이후에 낮은 온도($10^{\circ}C$이하)로 착색이 진행되지 않아서 동해피해로 수확을 포기해야 한다. 어느 시기까지 인공수분을 해야 당년에 안정적인 수확이 가능한지를 알아보고자 패션프루트의 후기(2차) 개화시기 중에서 8월 30일, 9월 10일, 9월 20일, 9월 30일에 인공수분 하여 11월 하순에 착색이 정상적으로 진행되는 처리를 조사한 결과 8월 30일 처리구만 11월 21일 착색이 되었다. 미착색과에서 내용물이 진노랑색으로 진행되면 후숙하여 상품과로 판매가 가능하기 때문에 진노랑색에 도달한 시기를 조사하였다. 조사에서 9월 10일까지 인공수분 처리한 과실은 후숙하여 상품과로 판매가 가능하였다.

This study attempted to investigate the possibility of Passiflora caerulea extract as a cosmetic material by measuring its antioxidant activities and melanin biosynthesis-inhibiting effects. For this, the substance was extracted with 70% ethanol, and ABTS radical scavenging activities were measured, using the TEAC assay. In addition, cell viability through the neutral red assay, ROS inhibition and inhibition of melanin biosynthesis were analyzed, and the results found the followings: In terms of ABTS radical scavenging activities of the extract, dose-dependent scavenging activities were observed. In trolox used as a positive control group and 0.1 mg/mL, similar radical scavenging activities were found. The production of ROS through CFDA was inhibited in a dose-dependent fashion. Furthermore, inhibition of melanin biosynthesis induced by 𝛼-MSH was confirmed. Therefore, it is reasonable to conclude that Passiflora caerulea extract has a potential as a cosmetic ingredient.
