General description
丁酸是一种含有四个碳的饱和短链脂肪酸。它通常以酯的形式存在于动物脂肪和植物油中。它是一种有效的细胞分化剂，也具有抗增殖活性。在培养的哺乳动物细胞中，它会影响生长速度、形态和基因表达。它还诱导细胞凋亡。
Application
该分析标准也可按如下方式使用：
- 高效液相色谱法（HPLC）与紫外检测相结合的方法的开发和验证，用于测定细菌培养样品中液-液萃取（LLE）后的四种短链脂肪酸甲酸—、乙酸、丙酸、丁酸和乳酸
- 采用高效液相色谱-折射率检测器和气相色谱-火焰离子化检测器同时分析韩国传统发酵豆酱（doenjang，大酱）18 个样品中的 10 种挥发性和非挥发性有机酸
- 采用反相高效液相色谱（HPLC）和毛细管电泳（CE）结合二极管阵列检测（DAD）测定酸性木薯淀粉废水样品中的丁酸、乳酸、乙酸和丙酸
- 采用气相色谱法结合火焰离子化检测器（GC-FID）对小鼠结肠生物样品中 6 种短链脂肪酸乙酸—、丙酸、丁酸、异丁酸、戊酸和异戊酸进行多残留分析
- 采用聚吡咯纳米纤维从儿童尿液样本中提取 8 种短链脂肪酸的填充纤维固相萃取（PFSPE），用于气相色谱-质谱分析（GC-MS）定量
- 采用气相色谱-质谱联用技术对大枣提取物中 76 种挥发性化合物进行多残留分析

We describe a procedure for preparing fecal samples for determination of volatile fatty acids (VFAs) by gas-liquid chromatography (GLC) and "high-performance" liquid chromatography (HPLC). The simple, one-step procedure involves only ultrafiltration through a membrane with a molecular-mass cutoff of 3000
