‘Goha’, ‘Gangha’, ‘Gwanha’, and ‘Yeolha’ are newly-developed Korean everbearing strawberry ( Fragaria ananassa Duch.) cultivars. Bioactive phytochemicals play a crucial role in the prevention of cancer, cardiovascular, neurodegenerative, and metabolic diseases. We examined the free radical scavenging activity and α-glucosidase inhibitory activity in these four cultivars and a junebearing cultivar ‘Seolhyang’ for comparison. ‘Gwanha’ showed the strongest 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radical scavenging activities, and ‘Gwanha’ and ‘Goha’ had the most potent α-glucosidase inhibitory activity. Total anthocyanin content (TAC) was the highest in ‘Gwanha’. The major anthocyanin components of everbearing strawberry were determined to be pelargonidin-3- O -glucoside (Pg3G), pelargonidin-3- O -rutinoside, and cyanidin-3- O -glucoside (C3G). A correlation study between activity and components revealed that TAC was highly correlated with antioxidant and antihyperglycemic activities, and in principal component analysis, C3G is highly correlated with antioxidant activity and Pg3G is highly correlated with the antihyperglycemic effect of everbearing strawberries. Among the four everbearing strawberry cultivars, ‘Gwanha’ and ‘Goha’ are rich sources of pelargonidin showing strong α-glucosidase inhibitory activity and are promising dietary sources to prevent diabetes.

四个永生草莓品种的抗氧化和抗高血糖活性潜力

“Goha”、“Gangha”、“Gwanha”和“Yeolha”是韩国新开发的草莓(Fragaria ananassa Duch.)栽培品种。生物活性植物化学物质在预防癌症、心血管疾病、神经退行性疾病和代谢疾病方面发挥着至关重要的作用。我们检查了这四个品种和一个 6 月品种 'Seolhyang' 的自由基清除活性和 α-葡萄糖苷酶抑制活性以进行比较。'Gwanha' 表现出最强的 2,2-diphenyl-1-picrylhydrazyl (DPPH) 和 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) 自由基清除活性,而 'Gwanha' 和'Goha' 具有最有效的 α-葡萄糖苷酶抑制活性。'Gwanha' 中的总花青素含量 (TAC) 最高。经测定,永生草莓的主要花青素成分为天竺葵素-3-O-葡萄糖苷(Pg3G),pelargonidin-3-O-rutinoside 和 cyanidin-3-O-glucoside (C3G)。活性与成分相关性研究表明,TAC与抗氧化和降血糖活性高度相关,主成分分析中,C3G与抗氧化活性高度相关,Pg3G与永生草莓的降血糖作用高度相关。在四个常生草莓品种中,'Gwanha' 和 'Goha' 是天竺葵素的丰富来源,显示出强大的 α-葡萄糖苷酶抑制活性,是预防糖尿病的有希望的膳食来源。C3G 与抗氧化活性高度相关,Pg3G 与常生草莓的抗高血糖作用高度相关。在四个常生草莓品种中,'Gwanha' 和 'Goha' 是天竺葵素的丰富来源,显示出强大的 α-葡萄糖苷酶抑制活性,是预防糖尿病的有希望的膳食来源。C3G 与抗氧化活性高度相关,Pg3G 与常生草莓的抗高血糖作用高度相关。在四个常生草莓品种中,'Gwanha' 和 'Goha' 是天竺葵素的丰富来源,显示出强大的 α-葡萄糖苷酶抑制活性,是预防糖尿病的有希望的膳食来源。
