将艾草在氯仿、甲醇和水（5：5：1）的混合溶剂中室温浸泡7天，上清液加水分两层。通过1H和13 C-NMR光谱和熔点的测量证实，从氯仿层中获得了三十七烷（C37 H76），而在甲醇-水层中发现了具有邻苯二酚衍生物的缩合单宁。几种艾绒中C_（37）H_（76）占艾草总重量的比例，上等艾绒与下等艾绒相近，但单宁含量上等艾绒明显低于下等艾绒。将燃烧温度曲线与提取后和提取前的艾草之间的时间进行比较，燃烧温度从25 ℃上升的时间。处理后的艾草从最高温度到最高温度的时间较长。从原始艾草中去除C37 H76似乎会减缓艾草的燃烧。
Moxa was soaked in a mixed solvent of chloroform, methanol and water (5 : 5: 1) at room temperature for 7 days, and the supernatant solution was separated into two layers by the addition of water. Heptatriacontane (C37H76), confirmed by measurements of 1H and 13C-NMR spectra and melting point, was obtained from the chloroform layer, while condensed tannins having catechol derivatives were found in the methanol-water layer. Each ratio of C37H76 in several kinds of moxas to the total weight of the moxa was similar in both high-class and low-class moxas, but that of the tannins was much less in the former than the latter. Comparing the burning-temperature curve to the time between the moxa after the extraction and before, the time for the rise of the burning-temperature from 25.degree. C to the highest temperature was longer in the treated moxa. Removal of C37H76 from the original moxa seems to decelerate the burning of moxa.
