The volatile compounds of trogopterorum feces were collected by using a simultaneous distillation and extraction (SDE) equipment. The chemical composition of the enriched volatile was examined by means of capillary gas chromatography (GC) and combined GC-mass spectrometry (MS). Fifty one constituents of the volatile were preliminarily identified by GC-MS, which amounted to 56.3% of the total peak area. Of these compounds, 33 were further verified by measuring their temperature-programmed retention indexes (TPRI) or retention times. They amounted to 35.7 % of the total peak areas. The main constituents of the volatile are dedecanoic acid (7.00%);alphacedrol (4.41%); pyrazine, tetramethyl-(4. 10%); tetradecanoic acid (3.37%); ethanone, 1-(3-methylphenyl)- (2.53%); benzaldehyde (2.42%); phenol, 2-methoxy-(2.11% ). The compound classes consist of alcohols (10), ketones (8), aldehydes (6), olefines (5), acids (4), and phenols (4).

Objective:To explore the effect of self-made mold in the spreading moxibustion of patients in the Department of Spine Orthopedics.Methods:From January 2019 to September 2020, convenience sampling was used to select 160 patients with spreading moxibustion in the Department of Spine Orthopedics of Liuzhou Traditional Chinese Medicine Hospital as the research objects. According to the order of treatment, patients were randomly divided into the control group and the experimental group, with 80 cases in each group. The control group used conventional methods for spreading moxibustion, and the experimental group used self-made molds for spreading moxibustion. The ginger column cracking of the two groups of patients, and operation time of 6 operators for spreading moxibustion on the two groups of patients was compared.Results:The cracking rate of ginger columns in the experimental group was lower than that in the control group, and the difference was statistically significant ( P<0.01) . The operation time of the 6 operators on the patients in the experimental group was (2.5±0.23) min, which was shorter than (18.5±0.41) min in the control group, and the difference was statistically significant ( P<0.01) . Conclusions:The application of self-made molds can shorten the spreading moxibustion operating time of operators and reduce the cracking rate of ginger columns, which is worthy of clinical application.
