Aromatic tobacco extractive and electronic cigarette juice

The invention discloses aromatic tobacco extractive and electronic cigarette juice. According to the aromatic tobacco extractive, the tobacco leaves, the pipe tobacco, the tobacco waste and/or the soot of aromatic tobacco are used as raw materials, and an extraction solvent is added into a Soxhlet extractor to carry out Soxhlet extraction on the raw materials. Improvement lies in the fact that a condensation pipe of the Soxhlet extractor is connected with a vacuum pump, so that the vacuum degree of the Soxhlet extractor is maintained at 20-80 mmHg. The temperature of condensation liquid in the condensation pipe is below -5 DEG C. After Soxhlet extraction, extraction liquid is collected and is concentrated, and the aromatic tobacco extractive is obtained. A whole Soxhlet extraction system is at a negative-pressure state, the boiling point of the extraction solvent is lowered, extraction temperature is lowered, during extraction, solvent circulating is accelerated, extraction frequency is accelerated, and efficiency is high. Meanwhile, solvent heating temperature is low, the extraction condition is mild, excessive chemical reaction between aroma components in the extractive caused by solvent high-temperature heating is avoided, and the amount of extractive offensive odor is small.
