This study investigated the effect of co-ingesting Natal plums () and Marula nuts () on the bioaccessibility and uptake of anthocyanins, antioxidant capacity, and the ability to inhibit α-glucosidase. A Natal plum-Marula nut bar was made by mixing the raw nuts and the fruit pulp in a ratio 1:1 (/). The cyanidin-3--sambubioside (Cy-3-Sa) and cyanidin-3--glucoside content (Cy-3-G) were quantified using the ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UHPLC/Q-TOF-MS). Inclusion of Natal plum in the Marula nut bar increased the Cy-3-Sa, Cy-3-G content, antioxidants capacity and α-glucosidase inhibition compared to ingesting Marula nut separately at the internal phase. Adding Natal plum to the Marula nut bar increased bioaccessibility of Cy-3-Sa, Cy-3-G, quercetin, coumaric acid, syringic acid and ferulic acid to 80.2% and 71.9%, 98.7%, 95.2%, 51.9% and 89.3%, respectively, compared to ingesting the Natal plum fruit or nut separately.
本研究调查了同时摄入南非蒲桃（）和猴面包果（）对花色苷生物利用度和吸收、抗氧化能力以及抑制α-葡萄糖苷酶能力的影响。通过将生坚果和果肉按 1:1（/）的比例混合，制成南非蒲桃-猴面包果棒。采用超高效液相色谱-四极杆飞行时间质谱（UHPLC/Q-TOF-MS）定量分析矢车菊素-3-桑布双糖苷（Cy-3-Sa）和矢车菊素-3-葡萄糖苷（Cy-3-G）的含量。与单独食用猴面包果相比，在内部相同时摄入南非蒲桃可提高 Cy-3-Sa、Cy-3-G 含量、抗氧化能力和α-葡萄糖苷酶抑制率。与单独食用南非蒲桃果实或坚果相比，将南非蒲桃添加到猴面包果棒中可使 Cy-3-Sa、Cy-3-G、槲皮素、咖啡酸、丁香酸和阿魏酸的生物利用度分别提高到 80.2%和 71.9%、98.7%、95.2%、51.9%和 89.3%。
