Device and method for extracting chemical composition from plant

Abstract

The invention relates to a device used for quickly extracting chemical constituents from plants and a method thereof, which belongs to the field of chemical analysis technology. An extracting device comprises a cylinder, a plunger rod, a filtering screen plate and a faucet, the plunger rod is arranged on the internal upper end of the cylinder, the filtering screen plate is arranged on the internal lower end of the cylinder, the faucet is arranged on the external lower end of the cylinder. Different extracting solvents can be chosen according to the properties of the chemical constituents of the plants, in the condition of the rotating speed of 14,000 to 22,000r / min, high-speed agitation can be carried on for 0.5 to 2min, then the faucet is opened, external pressure is added for filtering, and filter residue is stirred with the solvents for reextraction. The device of the invention gathers the extracting samples and the filtering into a device can reduce the loss of samples in the transferring and extracting processed, at the same time, through adding external pressure for filtering, filtering speed can be improved, so the extracting process is only 10 to 20 minutes, thus achieving the good extracting effect, simple and fast operation and the hign practicality.

Description

technical field [0001] The invention relates to a device and method for quickly extracting chemical components in plants, belonging to the technical field of chemical analysis. In particular, it relates to rapid extraction technology of phytochemical residues. Background technique [0002] Extracting the chemical components to be tested from plant samples is the key to analysis and detection. The current extraction and filtration device is two independent units. The sample is extracted in the extraction bottle and transferred to the filtrate collection bottle through the filter device. The entire extraction process takes a long period, and the sample has to be transferred many times, which is easy to cause the loss of the target to be measured. , especially for trace components, multiple transfer extractions are likely to cause the loss of the target to be analyzed and affect the accuracy of the analysis results.
