Embodiment 1

[0070] Weigh about 7mg of one-year-old moxa from a real estate in Jiangxi (the ratio of leaf to cashmere is 5:1), and put it into the Al 2 o 3 In the crucible, set the temperature program range to 28-900°C, the heating rate to 10°C / min, the reaction gas to be oxygen, and the flow rate to be 20mL / min, to obtain the data of the change of sample mass and heat flow with time, After normalization, we get figure 1 with figure 2 .

[0071] The thermal degradation process of moxa is divided into four stages. Stage I (28°C-160°C) is the stage of water evaporation and loss of volatile substances, Stage II (160°C-363°C) is the stage of oxidative decomposition and combustion, stage III (363 ℃~426℃) and IV (426℃~900℃) are the stages of charring combustion and burnout. Stage II is the main thermal degradation stage, with a weight loss rate of 59.0% and a maximum weight loss rate of 7.8% / min; the sum of the weight loss rates of stages III and IV is 27.5%, and a maximum weight loss rate ...

Embodiment 2

[0074] Weigh about 8 mg of one-year-old moxa from a real estate in Jiangxi (the ratio of leaf to cashmere is 10:1), and put it into the Al 2 o 3 In the crucible, set the temperature program range to 35-900°C, the heating rate to 10°C / min, the reaction gas to be air, and the flow rate to be 100mL / min, to obtain the data on the change of sample mass and heat flow with time, After normalization, we get image 3 with Figure 4 .

[0075] The thermal degradation process of moxa is divided into four stages. Stage I (35°C-124°C) is the stage of water evaporation and loss of volatile substances. Stage II (124°C-345°C) is the stage of oxidative decomposition and combustion. Stage III (345°C) ℃~419℃) and IV stage (419℃~900℃) are charring combustion and burnout stages. The weight loss rate of stage II was 60.1%, and the maximum weight loss rate was 15.2% / min; the sum of the weight loss rates of stage III and IV was 25.7%, and the maximum weight loss rate was 7.7% / min. The ratio of w...

Embodiment 3

[0078] Weigh two parts of about 7.5 mg of one-year-old moxa from a real estate in Henan (the ratio of leaf to cashmere is 5:1), put them into the crucibles of thermogravimetric (TG) and differential thermal analyzer (DSC) respectively, and set the temperature program range to 30 ℃~900℃ and 100℃~600℃, the heating rate is 10℃ / min, the reaction gas is air, and the flow rate is 100mL / min, the data of the change of sample mass and the change of heat flow with time are obtained, and the After sorting, the result is as follows Figure 5 with Image 6 shown.

[0079] The thermal degradation process of moxa is divided into four stages. Stage I (30°C-136°C) is the stage of water evaporation and loss of volatile substances. Stage II (136°C-368°C) is the stage of oxidative decomposition and combustion. Stage III (368°C) ℃~434℃) and stage IV (434℃~900℃) are the stages of charring combustion and burnout. The weight loss rate of stage II was 57.9%, and the maximum weight loss rate was 7.0...

Abstract

The invention discloses a quality determination and identification method of a material for moxibustion therapy, and belongs to the field of traditional Chinese medicines and massive health. A thermal weight loss analyzer (TG) and a differential scanning calorimeter (DSC) and / or a synchronous thermal analyzer (TG / DSC) are adopted to detect thermal weight loss indexes and reaction heat release performance of the moxibustion material, and the moxibustion material is quantitatively identified and evaluated according to indexes such as weight loss ratio, weight loss rate, combustion duration, heat flow, combustion heat release, heat release proportion in different combustion stages and the like. The method is easy to operate, convenient and visual, essential characteristics of moxibustion material thermal therapy can be directly reflected, folium artemisiae argyi (moxa) can be accurately identified, and the defect of moxibustion material identification is overcome.

Description

technical field [0001] The invention relates to the fields of traditional Chinese medicine and general health, in particular to a method for measuring and identifying the quality of moxibustion materials. Background technique [0002] Moxibustion therapy is one of the most distinctive basic therapies of traditional Chinese medicine, embodies the broad wisdom of the Chinese nation, has a history of thousands of years, and is a treasure of traditional Chinese medicine. Moxibustion mainly uses moxa sticks or moxibustion velvet as moxibustion materials. After being ignited, it is smoked and ironed or warmed on the body surface acupoints or diseased parts. It prevents and treats diseases through the thermal stimulation effect of heat and light. Significant curative effect. [0003] Artemisia argyi leaves are derived from the dried leaves of Artemisia argyi Levl.et Vant., and the processed moxa is the best material for moxibustion in the clinical practice of traditional Chinese m...
