Fig. 1From: Steam distillation/drop-by-drop extraction with gas chromatography–mass spectrometry for fast determination of volatile components in jujube (Ziziphus jujuba Mill.) extractThe diagram of steam distillation/drop-by-drop extraction device. (The device is suitable for extraction of volatile oils from extract. e.g. The jujube extract is produced by the following procedure: The jujube fruit was cleaned and denucleated. The pitted jujubes were then crumbed and extracted using alcohol. Then, the solvent was removed to produce the jujube extract)Back to article page
