不同参数艾条温和灸红外辐射光谱特性研究

目的比较不同松紧度、不同存储时间、不同叶绒比艾条施灸时的红外光谱特性,为艾绒生产、存储及临床应用中的参数选择提供科学依据。方法应用高灵敏红外光谱检测系统,检测4种不同松紧度、5种不同存储年份(1年、2年、3年、5年、7年)、4种不同叶绒比(5:1、10:1、15:1和30:1)艾条红外光谱并进行对比分析。结果不同松紧度、不同存储年份、不同叶绒比艾条燃烧时特征红外光谱均为3.75mm;不同松紧度的艾条燃烧时所产生的红外光谱强度之间比较差异无统计学意义(P>0.05);3年陈和5年陈艾条温和灸的红外辐射强度显著大于1年陈和7年陈艾条(P<0.05),但3年陈和5年陈艾条、1年陈和7年陈艾条比较差异无统计学意义(P>0.05);不同叶绒比(5:1、10:1、15:1和30:1)艾条温和灸红外光谱比较差异无统计学意义(P>0.05)。结论从红外物理角度看,艾绒存储年限以3~5年为佳,5:1叶绒比艾绒已可满足临床需要,无需过分追求太高的叶绒比。

Study on the Spectral Characteristics of Infrared Radiation of Mild Moxa-stick Moxibustion with Different Parameters

Objective To provide scientific basis for parameter selection in the production,storage and clinical application of moxa by comparing the infrared spectrum characteristics of moxa sticks with different tightnesses,storage times and leaf-moxa ratios during moxibustion.Method The infrared spectra of moxa sticks with four different tightnesses,five different storage years(1,2,3,5 and 7 years)and four different leaf-moxa ratios(5:1,10:1,15:1 and 30:1)were detected using a highly sensitive infrared spectrum detection system and analyzed by comparison.Result The characteristic infrared spectra of moxa sticks with different tightnesses,storage years and leaf-moxa ratios all were 3.75mm during combustion.There was no statistically significant difference in the intensity of infrared spectrum produced by combustion between moxa sticks of different tightnesses(P>0.05).The infrared radiation intensity of mild moxibustion with 3-year-stored and 5-year-stored moxa sticks was significantly higher than that with1-year-stored and 7-year-stored moxa sticks(all P<0.05),but there was no significantly significant difference between 3-year-stored and 5-year-stored moxa sticks and between 1-year-stored and 7-year-stored moxa sticks(all P>0.05).There was no significantly significant difference in infrared spectrum between mild moxibustion with moxa sticks of different leaf-moxa ratios(5:1,10:1,15:1 and 30:1)(P>0.05).Conclusion From the viewpoint of infrared physics,the storage life of moxa is preferably 3 to 5 years;the moxa with leaf-moxa ratio of 5 to 1 can meet the clinical needs;there is no need to excessively pursue a too high leaf-moxa ratio.
