부평초(Spirodelae Herba)는 무엇인가? | 부평초(Spirodelae Herba)는 개구리밥과(Lemnaceae)에 속한 다년생 수생식물인 개구리밥(Spirodela polyrhiza (L.) Schleid)과 청평(Lemna minor L.), 좀개구리밥(Lemna paucicostata Hegelm)의 전초를 건조한 것으로, 6월9월 사이에 채취하여 씻어 불순물을 제거한 다음 건조하여 치료에 사용되고 있는 한약재이다. 부평초의 성분에 관한 연구로 개구리밥(S. | |
광노화는 피부에 어떠한 영향을 끼치는가? | 외인적 노화는 외부 스트레스에 의해 노화 현상이 나타나는 것으로 자외선에 의한 광노화가 주된 원인이다. 자외선을 받게 되면 교원질(collagen) 및 탄력섬유(elastin fiber) 등의 기질 단백질이 손상되어 피부 내 교원질의 양이 부족해지고 탄력섬유가 변성되어 주름을 유발하며 기미, 주근깨 및 검버섯이 증가하는 현상을 보인다[7,8]. 또한 자외선에 노출되면, α-melanocyte stimulating hormone (α-MSH), adrenocorticotropic hormone 등의 신호전달물질을 멜라닌세포로 분비하게 된다[9]. | |
개구리밥(S. polyrhiza)에 존재하는 성분은 어떤 것들이 있는가? | 부평초의 성분에 관한 연구로 개구리밥(S. polyrhiza)에서 campesterol, β-sitosterol, stigmasterol 등의 sterol [13]과 apigenin-7-O-β-D-glucoside, cynaroside, hypolaetin-8-O-β-D-glucoside, vitexin, orientin 등의 flavonoid, anthocyanin 및 tannin 등이 보고되어 있다[14,15]. 예로부터 한방과 민간에서는 부평초를 말려 부종, 수종, 갈증, 강장, 발한, 해독, 충독, 수독, 양모, 당뇨병, 창종, 화상 등 피부와 관련된 질환의 약재로 사용하였으며[16,17] 이를 근거로 아토피관련 효능, 피부재생관련 효능, 항염증관련 효능, 피부 진정관련 효능, 피부미백관련 효능을 객관적으로 검증하여 바이오 소재화할 수 있을 것으로 사료된다. |
