| Abstract: | The Formica aquilonia Yarrow is used as the experimental material in this paper. Its moisture content accounts for 41. 58% by the drying method; the ash content is 16. 01% by ignition; the content determination of the crude fat extract from the petroleum ether is 25.98% in average; the content of acid is determined with acidometer using three concentrations of ethanol as extract and the results shows that the extraction of the 80% is the fullest. |
