采用对氨基苯磺酸-盐酸萘乙二胺分光光度法测定了陈皮对亚硝酸盐的清除率,研究了影响陈皮清除亚硝酸盐的因素。结果表明,65%的乙醇、60℃水浴提取1 h、反应20 min、提取液用量4 mL时陈皮乙醇提取液对亚硝酸盐清除率最大。
The nitrite clearance rate of tangerine peel was determined by sulfanilic acid-naphthylethylenediamine hydrochloride spectrophotometry, and the factors affecting the clearance of nitrite from tangerine peel were studied. The results showed that the 65% ethanol, 60 °C water bath extract 1 h, the reaction 20 min, the amount of extract 4 mL when the ethanol extract of tangerine peel nitrite clearance rate is the largest.
