Abstract

For the sunscreen development from natural resources, a possible usage of microalgal extracts or mycosporine-like amino acids (MAAs) was investigated. Sunscreens containing 7% of microalgal extracts or MAAs derived from microalgae, Chlamydomonas hedleyi, were prepared and they were applied to human research. Through this clinical research, the values of Sun Protection Factors, Sun Protector Factor (SPF) and Protection Factor of UVA (PFA), of sunscreen containing microalgal extracts or MAAs were determined: SPF values of microalgal extracts and MAAs indicated 9.07 and 9.42, respectively, while PFA ones did 2.43 and 2.41. Due to more than 2 of PFA value in both sunscreens, they can be classified into [PA+]. Taken together, although sunscreen containing microalgae-derived extracts or MAAs does not effectively protect UV irradiation, its capacity can be satisfied if inorganic UV-protecting compounds are added.

천연물 유래 자외선차단제 개발을 위해 미세조류 추출물 및 mycosporine-like amino acids(MAAs)의 활용가능성을 연구하였다. Chlamycomonas hedleyi 추출물과 추출물 분획물인 MAAs가 각각 7% 포함된 자외선차단크림을 제조하고 인체 적용시험을 실시하였다. 이를 통하여 자외선차단지수(SPF) 및 자외선 A차단지수(PFA)를 평가하였다. Ch. hedleyi 추출물과 MAAs 함유 자외선 차단 크림의 자외선 차단지수는 각각 9.07 및 9.42로 나타났으며, 자외선 A차단지수는 각각 2.43과 2.41로 측정되었다. 자외선 A차단지수가 모두 2 상으로 측정되어 두가지 자외선 차단크림의 자외선 A차단등급은 [PA+]으로 분류되었다. 이상의 연구결과는 미세조류 추출물 및 MAAs 함유 자외선차단제가 자외선을 효과적으로 막지 못하지만, 무기자외선 차단제가 혼합되면 만족할만한 자외선 차단효과를 보일 수 있을 것으로 판단된다.
