The free, esterified and insoluble-bound phenolics of defatted meals of camelina and sophia seeds were extracted using an ultrasonic-assisted procedure and alkaline hydrolysis. The antioxidant activities of the extracts were evaluated using DPPH and hydroxyl radical scavenging assays as well as inhibition of bleaching of β-carotene in an oil-in-water system. Moreover, inhibition activity against pancreatic lipase, α-glucosidase, low density lipoprotein (LDL) oxidation and DNA damage induced by peroxyl and hydroxyl radicals were examined for all seed extracts using in vitro systems. The seed extracts of camelina and sophia not only showed significant antioxidant activity but also inhibited pancreatic lipase and α-glucosidase activities effectively. These enzymes in the digestive tract are associated with lipid and carbohydrate digestion, respectively, and control obesity and blood glucose level in the human body. The findings of this work may provide supporting information that camelina and sophia meals may inhibit human LDL oxidation and DNA nicking caused by free radicals and upon consumption may also exert anti-obesity and antidiabetic effects. However, further research is required to confirm these biological activities in vivo. PRACTICAL APPLICATION The seed phenolic extracts of camelina and sophia not only showed significant antioxidant activity but also effectively inhibited the activities of pancreatic lipase and α-glucosidase. Thus, camelina and sophia seed meals may serve as nutritional ingredients with bioactive phenolics that show in vitro antioxidant and biological effects. However, further research is required to confirm these health effects in vivo.

亚麻荠和索菲亚种子酚类物质的生物活性:抑制 LDL 氧化、DNA 损伤以及胰腺脂肪酶和 α-葡萄糖苷酶活性

使用超声辅助程序和碱解法提取亚麻荠和索菲亚种子脱脂粉中游离的、酯化的和不溶性结合的酚类物质。使用 DPPH 和羟基自由基清除测定以及抑制水包油系统中 β-胡萝卜素的漂白来评估提取物的抗氧化活性。此外,使用体外系统检测了所有种子提取物对胰脂肪酶、α-葡萄糖苷酶、低密度脂蛋白 (LDL) 氧化和过氧自由基和羟基自由基诱导的 DNA 损伤的抑制活性。亚麻荠和索菲亚的种子提取物不仅具有显着的抗氧化活性,而且能有效抑制胰脂肪酶和α-葡萄糖苷酶的活性。消化道中的这些酶与脂质和碳水化合物的消化有关,分别控制人体内的肥胖和血糖水平。这项工作的发现可能提供支持信息,即亚麻荠和索菲亚餐可能抑制人体 LDL 氧化和自由基引起的 DNA 切口,食用后还可能发挥抗肥胖和抗糖尿病作用。然而,需要进一步的研究来证实这些在体内的生物活性。实际应用 亚麻荠和索菲亚种子酚类提取物不仅具有显着的抗氧化活性,而且能有效抑制胰脂肪酶和α-葡萄糖苷酶的活性。因此,亚麻荠和索菲亚种子粉可以作为具有生物活性酚类物质的营养成分,在体外显示出抗氧化和生物效应。然而,需要进一步的研究来证实这些体内的健康影响。并控制人体内的肥胖和血糖水平。这项工作的发现可能提供支持信息,即亚麻荠和索菲亚餐可能抑制人体 LDL 氧化和自由基引起的 DNA 切口,食用后还可能发挥抗肥胖和抗糖尿病作用。然而,需要进一步的研究来证实这些在体内的生物活性。实际应用 亚麻荠和索菲亚种子酚类提取物不仅具有显着的抗氧化活性,而且能有效抑制胰脂肪酶和α-葡萄糖苷酶的活性。因此,亚麻荠和索菲亚种子粉可以作为具有生物活性酚类物质的营养成分,在体外显示出抗氧化和生物效应。然而,需要进一步的研究来证实这些体内的健康影响。并控制人体内的肥胖和血糖水平。这项工作的发现可能提供支持信息,即亚麻荠和索菲亚餐可能抑制人体 LDL 氧化和自由基引起的 DNA 切口,食用后还可能发挥抗肥胖和抗糖尿病作用。然而,需要进一步的研究来证实这些在体内的生物活性。实际应用 亚麻荠和索菲亚种子酚提取物不仅具有显着的抗氧化活性,而且能有效抑制胰脂肪酶和α-葡萄糖苷酶的活性。因此,亚麻荠和索菲亚籽粉可以作为具有生物活性酚类物质的营养成分,在体外显示出抗氧化和生物效应。然而,需要进一步的研究来证实这些体内的健康影响。
