Embodiment 1

[0041] A method for quickly identifying components of medicinal materials from different origins and different storage times, the steps of the method are as follows:

[0042] 1): Sampling: Weigh 0.5g sample into a 20mL headspace bottle, press the bottle cap tightly, and leave the sample after incubation for detection on the machine without other pretreatment processes;

[0043] 2) Test: the step 1) after hatching, the sample is tested with a gas-phase ion mobility spectrometer;

[0044] 3) Qualitative analysis: The difference spectrum of volatile organic compounds in the sample is given by the functional analysis software; the built-in NIST database and IMS database of the software can conduct qualitative analysis of substances.

[0045] The incubation condition in step 1) is: after incubation at 85° C. for 20 minutes.

[0046] Step 2) described gas-phase ion mobility spectrometer is Flavor Analyzer.

[0047] Step 3) The function analysis software is G.A.S.

[0048] 1. Th...

Abstract

The invention discloses a method for rapidly identifying compositions of medicinal materials at different origin places and with different storage time. The method comprises the following steps that (1) sampling is conducted, specifically, 0.05-0.5 g of samples are weighed and placed into a 20 mL of headspace bottle, a bottle cover is compressed, after being incubated, the samples wait for being detected on a machine, and other pre-treatment processes are not needed; (2) testing is conducted, specifically, the incubated samples in the step (1) are tested through a gas-phase ion mobility spectrometer; and (3) qualitative analysis is conducted, specifically, a difference spectrogram of volatile organic matter in the samples is given through functional analysis software, and the matter can bequalitatively analyzed through an NIST database and an IMS database which are set in the software. According to the method, under the premise of not needing sample pre-pretreatment after directly heating and headspace sample injection are conducted, volatile organic components of lysimachia foenum-graecum hance samples can be quickly detected, and the testing result well reflects the influence ofthe origin place and the storage time on lysimachia foenum-graecum hance aroma.

Description

technical field [0001] The invention relates to the field of drug testing, in particular to a method for quickly identifying the components of medicinal materials from different production areas and different storage times. Background technique [0002] At present, there are high performance liquid chromatography, high performance liquid chromatography tandem mass spectrometry, gas chromatography, gas chromatography tandem mass spectrometry, etc. for the detection of medicinal materials with different origins and different storage times, but there are the following disadvantages: 1) samples need to be processed before detection, and the detection time Long; 2) The sample pretreatment will damage the sample, and the sample cannot be recovered, especially the high performance liquid chromatography and high performance liquid chromatography tandem mass spectrometry. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the rel...
