Analysis of Components in Smoke and Air Pollutants of Moxa from Artemisia stolonifera and Artemisia argyi
Objective:To compare the volatile components in the smoke produced by burning moxa from Artemisia stolonifera and A.argyi with different germplasm resources,as well as the concentrations of indoor air pollutants,thereby providing scientific sup-port for the further development and utilization of A.stolonifera.Methods:Headspace solid-phase microextraction combined with gas chromatography-mass spectrometry(HS-SPME-GC-MS)was used to detect the volatile components in the smoke of burned moxa,followed by cluster analysis of all volatile components.An air quality detector was employed to measure concentrations of formalde-hyde,total volatile organic compounds(TVOCs),PM2.5,and PM10 in indoor air after burning the moxa.Results:A total of 111 volatile components were detected in the smoke from A.stolonifera moxa,with relative content ranging from 63.89％to 75.76％.For A.argyi moxa,106 components were detected,with relative content of 64.87％to 75.50％.A total of 147 volatile components were identified between the two resources,with 10 shared components.Cluster analysis grouped A.stolonifera samples AS1,AS2,and AS3 with A.argyi sample AA3 into one cluster;A.stolonifera samples AS4 and AS5 with A.argyi sample AA5 into one cluster;the remaining A.argyi samples into a separate cluster.The concentrations of formaldehyde,TVOCs,PM2.5,and PM 10 generated by burning A.stolonifera moxa were significantly lower than those of A.argyi moxa.Conclusion:The volatile components and their con-centrations in the smoke of A.stolonifera moxa and A.argyi moxa exhibit distinct differences.Both contain a considerable amount of alkenes and alkanes.The smoke from A.stolonifera moxa had a slightly higher alcohol content but a much lower phenol content than A.argyi moxa,with only small amounts of eucalyptol and borneol detected in A.argyi moxa smoke.The indoor air pollutant concen-trations after burning A.stolonifera moxa were significantly lower than those after burning A.argyi moxa.
