本研究主要是探討黑色素萃取物抗氧化特性。黑色素萃取物包括烏骨雞雞皮黑色素(silky skin melanin, SS-melanin)、烏骨雞雞冠黑色素(silky comb melanin, SC-melanin)、烏賊墨囊黑色素(sepia ink sac melanin, SE-melanin)及章魚墨囊黑色素(octopus ink sac melanin, OC-melanin)等四種,並與化學合成黑色素(synthetic melanin, SY-melanin)做一比較。黑色素萃取物,對於活性氧 (超氧陰離子) 與自由基 (DPPH•自由基和氫氧自由基) 有清除效應,且會隨著添加樣品濃度的增加而上升。
The objectives of this study were to investigate the possibility of melanin extracted from silky fowl comb (SC-melanin), silky fowl skin (SS-melanin), sepia ink sac (SE-melanin) and octopus ink sac (OC-melanin). Antioxident properties of melanin extracts were in contrast with SY-melanin. The result showed that melanin extracts had scavenging effects for active oxygen (superoxide anion) and free radical (DPPH • radical and HO • radical), and increased the ability with adding concentration.
