Abstract

In this study, Poria cocos bark were extracted by supercritical process, and anti-inflammatory, whitening, and antioxidant effects were measured in comparison with ethanol extract. Also, An effective percutaneous permeation method using a selected formulation of the extract and a drug delivery peptide was proposed. Pachymic acid, known as the anti-cancer and anti-inflammatory compound of the ventricle, is an indicator component and the HPLC analysis shows that the supercritical extract of the pericardium is more than twice that of the Poria cocos bark extract. In order to confirm antioxidative effect of Bombyx mori, DPPH scavenging ability and ABTS scavenging ability test showed that the ethanol extract of Poria cocos Back had lower concentration than the supercritical extract of Poria cocos back. However, RAW 264.7 Measurements of Nitric oxide (NO) production in cells showed lower NO production at the same concentration than the Poria cocos back ethanol extract. In addition, after 72 hours of processing of $20{\mu}g/mL$ of the Poria cocos back extract in B16 melanoma cells, both the intracellular and extracellular melanin extract were effective and the supercritical extract was lower melanin content. No toxicity was observed at the concentration of $800{\mu}g/mL$ in RAW 264.7 cells used in NO production experiments. However, in B16 melanoma cells, even at $50{\mu}g/mL$, both Poria cocos back ethanol extract and supercritical extract showed a survival rate of less than 60%. The liposome formulation and drug delivery peptides were shown to be useful for percutaneous permeation of Supercritical Extract of Poria cocos back using a liposome formulation and a drug delivery peptide. it is expected that there will be great potential for development as a variety of cosmetic materials for Poria cocos back.

본 연구에서는 초임계 공정에 의해 복령피를 추출하였고, 에탄올 복령피 추출물과 비교하여 항염, 미백, 항산화효과를 측정하였다. 또한 선정된 추출물의 제형과 약물전달 펩티드를 활용하여 효율적인 경피투과 방법을 제시하였다. 복령피의 항암, 항염성분으로 알려진 Pachymic acid를 지표성분으로 HPLC 분석 결과 에탄올 복령피 추출물 보다 초임계 복령피 추출물이 2배 이상 높게 추출되는 것으로 나타났다. 복령피의 항산화효과를 확인하기 위하여 DPPH 소거능과 ABTS 소거능은 복령피 에탄올 추출물이 초임계 복령피 추출물보다 더 낮은 농도에서 $IC_{50}$을 나타내었다. 하지만 RAW 264.7 세포 내 NO(Nitric oxide) 생성량을 측정한 결과에서는, 에탄올 복령피 추출물보다 초임계 복령피 추출물이 동일 농도에서 더 낮은 NO 생성량을 나타냈다. 또한 B16 melanoma 세포에 복령피 추출물을 $20{\mu}g/mL$ 농도를 72시간 처리 후 세포 내외 멜라닌 합성을 확인한 결과에서는, 에탄올 복령피 추출물과 초임계 복령피 추출물 모두 효과가 있었으며 초임계 추출물이 더 낮은 멜라닌 함량을 보였다. NO 생성량 실험에서 활용된 RAW 264.7 세포에서는 $800{\mu}g/mL$농도에서도 독성이 나타나지 않았다. 하지만 B16 melanoma 세포에서는 $50{\mu}g/mL$에서도 에탄올 추출물과 초임계 추출물 모두 60 % 미만의 생존율을 나타냈다. 초임계 복령피 추출물을 대상으로 리포좀 제형과 약물전달 펩티드를 활용하여 Franz diffusion cell 실험 결과에서는, 리포좀 제형과 약물 전달 펩티드가 초임계 복령피 추출물을 경피 투과를 증진시켜 주는 것으로 나타났다. 초임계 복령피 추출물이 다양한 효능의 화장품 소재로서 개발될 가능성이 있다고 판단된다.
