技術說明

紫外光(ultraviolet light, UV)因其波長的不同，可分成UVA (320 – 400 nm)、UVB (280 – 320 nm) 及UVC (200 – 280 nm) 等三種。UVC會被大氣臭氧層吸收後無法直接照射到地表，只有UVA及UVB可以到達地表，一般照射到地表之紫外光有5~10% 屬於UVB，而90~95%屬於UVA。雖然UVB只佔到達地表紫外光的少部分，但由於其能量最大，因此對於人體皮膚的傷害力也最大。紫外光中的UVB能量最強，可穿透至表皮層，造成表皮肥厚、角質增厚以及皮膚紅腫發炎等症狀發生，長期曝曬UVB會直接破壞細胞內之DNA，使DNA產生突變，同時會使皮膚產生活性氧物質，造成蛋白質、脂質及細胞膜的破壞，並間接造成細胞DNA的突變。本案係關於一種香蕉皮萃取物的用途，係藉由香蕉皮萃取物使皮膚可以免於受到UVB造成的傷害，例如細胞死亡、發炎因子IL-6生成、膠原蛋白破壞等，因而可以應用於製備保護細胞免於UVB造成傷害之藥物、保健食品或化妝品。 Ultraviolet (UV) light can be divided into UVA (320-400 nm), UVB (280-320 nm) and UVC (200-280 nm) basing on its different wavelengths. UVC cannot be directly irradiated to the earth’s surface because it will be absorbed by the atmospheric ozone layer. Only UVA and UVB can reach the earth’s surface. General exposure to the earth’s surface of the UV light is 5-10% of UVB, and 90 -95% of UVA. Because UVB has the highest energy among the three types of UV light, its damage to human skin is the largest. UVB can penetrate to the epidermis, resulting in epidermal hypertrophy, cuticle thickening, skin irritation and other symptoms of inflammation. The present invention concerns the use of a banana peel extract which protects the skin from damage caused by UVB, such as cell death, formation of inflammatory factor IL-6, and collagen damage. And thus this extract can be used in the preparation of medicines, health foods or cosmetics for protecting cells from damage caused by UVB.
