A basic, extractable, indolic type of compound, which was derivatized with heptafluorobutyric anhydride and pyridine, was obtained from the cerebrospinal fluids of patients with acute tuberculous meningitis. The compound was detected by frequency-pulsed, modulated electron capture gas-liquid chromatography, and it was tentatively identified by mass spectrometry as 3-(2'-ketohexyl)indoline. The compound was found to be valuable for differentiating between tuberculous, cryptococcal, and aseptic meningitides.
从急性结核性脑膜炎患者的脑脊液中获得了一种基本的、可提取的吲哚类化合物,该化合物用七氟丁酸酐和吡啶进行了衍生化。通过频率脉冲调制电子捕获气液色谱法检测该化合物,并通过质谱法初步鉴定为3-(2'-酮己基)吲哚啉。发现该化合物对于鉴别结核性、隐球菌性和无菌性脑膜炎有价值。
