| 目的：探讨中药辟瘟线香对空气中自然菌的抑制作用。方法：选择实验室、居家客厅和居家卫生间，采用平板暴露法，于熏香前后进行空气采样，37℃培养48 h后计算沉降菌总数、空气中自然菌消亡率。结果：艾草本辟瘟线香、苍降辟瘟香熏香前后沉降菌总数比较，差异均有统计学意义（P<0.05）；艾草本辟瘟线香、苍降辟瘟香空气中自然菌消亡率与市售化学线香比较，差异均有统计学意义（P<0.05）。艾草本辟瘟线香熏香沉降菌总数0 h与1 、2 h比较，差异有统计学意义（P<0.05）。2 h自然菌消亡率峰值达86.2%，继续熏香至4 h消亡率为86.9%，差异无统计学意义（P>0.05）。结论：艾草本辟瘟线香和苍降辟瘟香杀菌作用强，效果维持长，简便易行，可作为空气抑菌剂，适合在家庭、学校、办公室等地方进行空气净化使用。 |

| Abstract: |
| Objective：To investigate the inhibitory effect of the traditional Chinese medicine joss-stick for epidemic prevention on natural bacteria in air.Methods：Sampling sites included laboratories,living rooms,and bathroom,by placing ptates to exposure to air.The sampling was carried out before and after the incense was burnt.The total number of sedimented bacteria and the inviability rate of natural bacteria in air were calculated after culture at 37°C for 48 hours.Results：There was a significant difference in the total number of bacteria colony after the burning of Artemisia argyi joss-stick and Tanarius major-Rhizoma Atractylodis joss-stick (P<0.05)，and there was also a significant difference in the inviability rate of natural bacteria in air between these two types of joss-stick and the commercially available chemical joss-stick (P<0.05).For the Artemisia argyi joss-stick，the total number of bacteria colony at 0 hour was significantly different from that at 1 and 2 hours (P<0.05).The inviability rate of natural bacteria reached 86.2% at 2 hours and 86.9% at 4 hours，with no significant difference between these two time points (P>0.05).Conclusion：Both Artemisia argyi joss-stick and Tanarius major-Rhizoma Atractylodis joss-stick have a strong antibacterial effect that can last for a relatively long term，and they are used easily and conveniently and can be used as a bacteriostatic agent for air purification in homes，schools，and offices. |
