Problems solved by technology

[0010] (3) Ethyl ether is used as one of the solvents forming the developing agent: ether is extremely volatile and lost, which can easily cause changes in the composition of the developing agent, resulting in poor reproducibility of this method
[0011] (4) The thin-layer chromatogram is only inspected at 365nm ultraviolet wavelength, and the chromatographic information obtained is not comprehensive enough

Embodiment 1

[0038] Weigh 0.5g of agarwood test sample powder, put it in a 50mL conical flask with a stopper, add 10mL of ethanol, seal it tightly, and place it in an ultrasonic treatment device with a power of 500W, a frequency of 30KHz, and a temperature of 30°C for 30 minutes. Allow to cool, filter, and take the subsequent filtrate as the test solution, referred to as the test ①. Take 0.5 g of agarwood as a reference medicinal material, and make a solution of the reference medicinal material in the same way, referred to as the control ①.

Embodiment 2

[0040] Weigh 0.5g of agarwood test sample powder, put it in a 50mL conical flask with a stopper, add 15mL of ethanol, seal it tightly, and place it in an ultrasonic treatment device with a power of 100W, a frequency of 50KHz, and a temperature of 40°C for 30 minutes. Allow to cool, filter, and take the subsequent filtrate as the test solution, referred to as the test ②. Take another 0.5 g of agarwood reference medicinal material, and make a reference medicinal material solution in the same way, referred to as control ②.

Embodiment 3

[0042] Weigh 0.5g of agarwood test sample powder, put it in a 50mL conical flask with a stopper, add 20mL of ethanol, seal it tightly, and place it in an ultrasonic treatment device with a power of 300W, a frequency of 40KHz, and a temperature of 30°C for 30 minutes. Let cool, filter, and take the subsequent filtrate as the test solution, referred to as the test ③. Take another 0.5 g of agarwood reference medicinal material, and make a reference medicinal material solution in the same way, referred to as control ③.

Abstract

The invention discloses an agilawood identifying thin-layer chromatography. The agilawood identifying thin-layer chromatography comprises the following steps: A, preparing a test solution : taking 0.5g of agilawood test sample powder, adding 10-20mL of ethanol, performing ultrasonic treatment for 20-30 minutes, naturally cooling, filtering, and taking filtrate as the test solution; B, preparing a control solution : taking 0.5g of agilawood control sample, adding 10-20mL of ethanol, performing ultrasonic treatment for 20-30 minutes, naturally cooling, filtering, and taking filtrate as the control solution; C, performing thin-layer chromatography: sucking 10 microliters of the solutions prepared in the steps A and B respectively, dotting the solutions on the same silica gel G thin plate, developing with ethyl acetate-acetone as a developing agent, with the developing distance of 12cm, taking out, drying, and viewing in ultraviolet lamp, wherein fluorescent spots with the same color are developed at corresponding positions of a chromatogram of the control sample and a chromatogram of the test sample. The agilawood identifying thin-layer chromatography is stronger in operability and better in reproducibility; the obtained thin-layer chromatogram information is more comprehensive.

Description

technical field [0001] The invention relates to the technical field of analysis and testing, in particular to an identification method of agarwood. Background technique [0002] Agarwood is a resinous wood of Agarwood and white wood, a plant of the genus Agarwood in the family Daphneaceae. [0003] Agarwood is a traditional Chinese medicine with a long history. It has the functions of promoting qi and relieving pain, warming the middle and relieving vomiting, invigorating qi and relieving asthma. , Agarwood Qu, Agarwood Yangwei Pills, etc. are the main ingredients of more than one hundred kinds of Chinese patent medicines. [0004] Agarwood is also a kind of precious spice, ranking first among the world's four famous incense "Agarwood Longmusk". [0005] Agarwood is the only plant resource for producing agarwood in my country; in recent years, due to excessive felling, agarwood resources are seriously lacking, and it has been listed as a national second-class endangered pl...
