METHODS The content of phillyrin in forsythia was determinated by using Soxhlet extractor with methanol, separation and purification with the neutral aluminum oxide column and HPLC method. 方法采用甲醇索氏提取,中性氧化铝柱层析分离纯化、高效液相色谱法测定连翘中连翘苷含量。
Orthogonal experiment of extraction of scutellarin acid with microwave or Soxhlet's extractor Pulps& Determination of dichloromethane soluble matter 微波与索氏提取野黄芩苷的正交实验比较GB/T7979-1987纸浆二氯甲烷抽提物的测定法
Method By using Soxhlet extractor, water and ethanol were used as medium respectively. 方法用索氏提取器分别以水、乙醇为浸提介质。
Method s: Soxhlet extractor was previously applied to grape seeds for the remover of oils with petroleum benzine. 方法:对新疆葡萄酒厂废渣中葡萄籽用石油醚脱脂,脱脂后的葡萄籽用乙醇提取。
Adsorbable organic components were isolated and concentrated by XAD series resins. Adsorbed organic components were extracted by Soxhlet extractor, and concentrated by KD concentrator, then qualitatively analyzed by GC/ MS. 可吸附组分用XAD系列树脂富集,树脂吸附物经索氏提取和KD浓缩后,用气相色谱/质谱法定性分析。
Taken sea-tangle as material, a study was carried out on extracting the fatty acid in sea-tangle by Soxhlet extractor, and an analysis was conducted to the fatty acid's components of sea-tangle by the technique of GC-MS. 以海带为原料,采用索氏提取器对海带脂肪酸进行提取研究,并应用GC-MS技术对海带脂肪酸成分进行分析。
RESULTS The optimal conditions for the extraction with soxhlet's extractor were A 3B 3C 1 and C 1B 3A 1 for that of microwave. 结果索氏提取优化工艺条件为A3B3C1,微波提取最佳条件为C1B3A1。
Methods: Repeatedly reflux extracted by Soxhlet extractor. 方法:索氏提取器多次回流提取。
Scallop fat was extracted by means of rapid fat extractor instead of Soxhlet extractor. 以快速脂肪提取法代替索氏法提取甲鱼脂肪。
Methods The Soxhlet extractor method was adopted for the extraction of pigments, and acid extraction and ethanol precipitation method was used for the preparation of pectin. 方法用索氏提取法提取色素,酸提取乙醇沉淀法制取果胶。
Petroleum ether extraction using a Soxhlet extractor cleared fats most thoroughly in a mild manner, but the volume of the extractor was limited, let alone a small quantity of bone cost large amounts of organic solvents. 石油醚索氏抽提法脱脂最为彻底,条件温和,但处理数量有限,且需耗费较多的有机溶剂。
