Abstract

This study was conducted to evaluate the biological activities of sweet potato tips and tubers. Antioxidant activity of 2,2-azino-bis 93-ethlbenzothiazoline-6-sulphonic acid) diammonium salt (ABTS) and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activities had the highest value of 32.45 mg, AAE/g, and 15.10 mg AAE/g, respectively, in '' tips. Angiotensin converting enzyme I inhibitory activity ranged between 47.72% in '' tubers and 62.25% in '' tips. α-Glucosidase inhibitory activity had the highest value of 78.81% and 62.93% in '' tips and '' tubers, respectively. In particular, '' tips had the most effective inhibiting effect on intracellular reactive oxygen species levels in HepG2 cells. Wound healing assay result revealed that '' showed 75% wound healing effect. For skin whitening, '' tips showed 63% activity at 10 mg/ml. These results suggest that sweet potato tips and tubers can be used to develop functional food and cosmetic materials.

摘要

本研究旨在评估红薯叶和块茎的生物活性。2,2-联氮-双-(3-乙基苯并噻唑啉-6-磺酸)二铵盐（ABTS）抗氧化活性和1,1-二苯基-2-苦基肼（DPPH）自由基清除活性在红薯叶中分别具有最高值32.45毫克抗坏血酸当量/克和15.10毫克抗坏血酸当量/克。血管紧张素转换酶I抑制活性在红薯块茎中为47.72%，在红薯叶中为62.25%。α-葡萄糖苷酶抑制活性在红薯叶和红薯块茎中分别具有最高值78.81%和62.93%。特别是，红薯叶对HepG2细胞内活性氧水平具有最有效的抑制作用。伤口愈合试验结果显示，[此处缺失具体品种名称]显示出75%的伤口愈合效果。对于皮肤美白，红薯叶在10毫克/毫升时显示出63%的活性。这些结果表明，红薯叶和块茎可用于开发功能性食品和化妆品原料。
