The influence of oxygen on the thermal treatment (TT) of secondary metabolite-enriched extracts (SMEEs) from Tórtola beans and procyanidin C1 (PC1) on the inhibition of advanced glycation end products (AGEs) generation in proteins was investigated. SMEE was incubated at 4 °C (control) or thermally treated at 60 °C for 2 h, at either 0 % O2 (I) or 20 % O2 (II). Treatments I and II increased the content of procyanidin dimers B2. Treatment II was more effective than the control or treatment I in preventing homocysteine oxidation and AGEs generation. TT of PC1 at 0 % or 20 % O2 generated procyanidin dimers and tetramers. PC1 TT at 20 % O2 exhibited higher oxidation potentials and lower IC50 values of fluorescent AGEs than those of controls or TT at 0 % O2. These findings indicate that SMEE from Tórtola beans after treatment II changes the degree of polymerization and oxidation procyanidins, thereby increasing their antiglycation activity.

在氧化条件下进行热处理可提高智利 Tórtola 豆 (Phaseolus vulgaris) 的抗氧化和抗糖化活性



研究了氧气对 Tórtola 豆和原花青素 C1 (PC1) 中富含次生代谢物的提取物 (SMEEs) 热处理 (TT) 对抑制蛋白质中晚期糖基化终末产物 (AGEs) 生成的影响。将 SMEE 在 4 °C(对照)下或在 60 °C 下以 0 % O 2 (I) 或 20 % O 2 (II) 热处理 2 小时。处理 I 和 II 增加了原花青素二聚体 B2 的含量。治疗 II 在预防同型半胱氨酸氧化和 AGEs 生成方面比对照组或治疗 I 更有效。PC1 在 0 % 或 20 % O2 下的 TT 生成原花青素二聚体和四聚体。20 % O2 的 PC1 TT 比对照或 0 % O2 的 TT 表现出更高的氧化电位和更低的荧光 AGEs IC50 值。这些结果表明,处理 II 后 Tórtola 豆的 SMEE 改变了原花青素的聚合和氧化程度,从而提高了它们的抗糖化活性。
