The invention relates to a method for quickly identifying
Ligusticum sinense based on an electronic
nose, which comprises the following steps: (1) respectively pulverizing a certain amount of
Ligusticum sinense,
ligusticum wallichii and a mixture of
Ligusticum sinense and
ligusticum wallichii mixed according to a gradient ratio to obtain a plurality of samples; (2) turning on an electronic
nose instrument, wherein the electronic
nose comprises a plurality of sensors, setting the parameters of the electronic nose as follows: the gas flow rate is 0.5-0.7 L / min, the cleaning time is 160-200s, the detection time is 100-150s, and starting sample introduction determination at 15-30 DEG C to obtain data of each sample in each sensor of the electronic nose; (3) finding out a group of data with the highest significance corresponding to different samples in different sensors, and taking the sensor corresponding to the group of data as a subsequent electronic nose detection sensor,
grinding a sample to be detected into
powder, and measuring the detection data of the sample to be detected in the sensor according to the conditions in the step (2); and (4) identifying the to-be-detected sample by taking the group of data with the highest significance as characteristic reference values according to the detection data of the electronic nose. The method is simple to operate, identification steps are simplified, and identification time is shortened.
