维吾尔传统藿香果酱的营养成分和抗氧化性能

Study on Nutritional Components of the Uyghur Traditional Food Agastache rugosus jam and Its Anti-oxidation Activity

采用紫外分光光度法,测定藿香果酱中VA、VC、总黄酮、总生物碱、胆固醇的含量;采用索氏抽提法提取藿香果酱中的脂肪和抗氧化成分,并测定其脂肪含量;用原子吸收分光光度法测定藿香果酱中钾、钠、锌、钙、铁、铜、锰、镁等8种微量元素的含量,并观察了藿香果酱乙醇提取物和VC对油脂的抗氧化性,将其分别添加到棉籽油、羊油脂中,利用Na2S2O3-I2滴定法分别测定乙醇提取物和VC对棉籽油、羊油脂的过氧化(POV)值;用分光光度法分别对藿香果酱乙醇提取物,VC,黄酮的清除羟自由基(.OH)的能力进行了测定和比较。结果表明:藿香果酱乙醇提取物和VC分别对棉籽油、羊油脂均有抗氧化作用,其中0.02%VC的抗氧化作用大于1.0%的乙醇提取物,随着提取物浓度的增加,抗氧化性能逐渐增强;藿香果酱乙醇提取物、VC、黄酮均有清除羟自由基的能力,其中0.02%黄酮标准品(芦丁)的清除能力最好,其次是0.02%VC和藿香果酱乙醇提取物;通过测定得知,每100g藿香果酱中VA和VC分别为41.90μg和31.13mg,总黄酮含量为30.16mg,总生物碱含量为250.58μg,胆固醇含量为57.38μg,总糖和膳食纤维的含量分别为60.06g和194.49mg;微量元素K和Na含量较高。藿香果酱乙醇提取物具有一定的抗氧化性和清除自由基的能力,可有效地延缓油脂的脂质过氧化反应。

Nutritional Components of Agastache rugosus jam （Agastache rugosus O. ktze） mcluding Vitamin ＆, Vitamin C, total flavonoid, total alkaloid, cholesterin, microelements, total fat and total sugar were determined. UV spectra was applied for the determination of the VA, Vc, flavonoid, alkaloid and cholesterin. Antioxidative components and total fat were extracted by soxhlet method. AAS Na, Zn, Ca, Fe, Cu, Mn, Mg in Agastache rugosus jam. seed oil and suet were studied through measuring peroxide showed that 0. 02% Vc has higher activity than the 1.0% was applied to determine the mineral elements such as K, Antioxidant activity of the ethanol extract and Vc on cotton value （POV） by Na2 S2 O3-I2 titrimatric method. The results ethanolic extract. With increasing of ethanolic extract concentration, the antioxidatant activity was also increased. Hydroxyl free radical（·OH） scavenging ability was tested and compared by UV spectraphotometric method. The results were： 0.02% standart Sample of Flavone（Rutin） had stronger ·OH eliminating ability than the 0. 02% Vc and ethanolic extract. There were 41.90 μg of VA and 31. 13 mg of Vc in every 100 g Agastache rugosus jam. The amount of the total flavonoids, alkaloids and cholesterol in every 100 g Agastache rugosus jam was 30. 16 mg, 250.58 μg and 57.38 μg respectively. The Amount of total sugar and meal cellulose was 60.06 g and 194.49 mg respectively. It had comparatively higher amount of K and Na elements. Ethanolic extracts of Agastache rugosus jam can delay lipid peroxidation of the oils and had the ability of free-radical elimination. This article provided preliminary data for the further investigation and exploitation of the Uyghur traditional health medicinal materials.
