The exact of petroleum ether was the acaricidal active site of Eungenia caryophyllata. 3.Isolation, purification and identification of compounds with acaricidal activity in Eugenia Caryphyllata: The exact of petroleum ether was separated into 6 parts by silica gel column chromatography with gradually increasing polarity of petroleum ether: ethyl acetate. The part C was demonstrated to be the most effective part by acaricidal activity test in vitro,and the time for it to kill all experimental mites was about 20 min.

丁香杀螨活性成分的追踪分离、纯化与结构鉴定：采用硅胶柱层析法，以石油醚：乙酸乙酯溶剂系统梯度洗脱，对丁香石油醚提取物进行分离，得到A~F 等6 段混合物，离体杀螨试验发现，C 段混合物具有突出的杀螨活性，50%浓度平均15min可杀死全部供试螨虫。

All the compounds were isolated and identified from the bituminous coals for the first time, bis(2-ethylheptyl) terephthalate and 18-ethyl-17-(hexan-2\'-yl) docosanoic acid are new compounds.Further more, a Colourless Oil Liquid, a white acerate crystals containing some alkanes, a white tabular crystals consisting of some fatty acid esters and a white powder crystals in which some fatty acids exist were isolated and analysed by GC/MS for the first time.Through this research, a study method of"classification extract of bituminous coal- separation with silica-gel and gelatin column chromatographies- identification of the isolated compounds by FTIR, GC/MS, LC/MS, 1H NMR and 13C NMR analyses"was established and proved to be a practical approach toward separable and non-destructive identification of some organic compounds in bituminous coals for coal chemistry research.
