The invention is a method of preparing glossy ganoderma triterpenic acid and amylase by glossy ganoderma, crushing the dry glossy ganoderma seeds (water content 5-8%) into particles; or cutting into slices, then putting raw material in a high-pressure extraction kettle, then injecting CO2 and polar agent in the extraction kettle by a supercritical CO2 high-pressure pump and a polar agent pump, respetively, where the extracting pressure of the high-pressure pump is 25-50 MPa, the injection quantity of the polar agent in bulk percent is 10-20%, the temperature is 35-80 deg.C, and the extracting time 2-4 hours, obtaining the extract of glossy ganoderma triterpenic acid; adding water by 8-16 times in the residues, heating to 80-100 deg.C, extracting for 1-2 hours, obtaining the extract of glossy ganoderma amylase. In the products prepared by this invention, the content of glossy ganoderma triterpenic acid is up to 60.2% (by HPLC detection); that of glossy ganoderma amylase 36% (by UV spectral detection). 一种从灵芝中制备灵芝三萜酸和灵芝多糖的方法，将干燥的灵芝子实体(含水量5-8％)破碎成粒状物，或切成片状物，然后将原料放入高压提取罐内，然后通过超临界CO#-[2]高压泵和极性剂高压泵分别向提取罐内注入CO#-[2]和极性剂，高压泵的提取压力为25-50MPa，极性剂注入量按体积百分比为10-20％，温度为35-80℃，提取时间2-4小时，得灵芝三萜酸提取液；提余物加入其质量百分比8-16倍的水，加热到80-100℃，提取时间1-2小时，得灵芝多糖提取液。本发明制备的产品中，灵芝三萜酸的含量达60.2％(HPLC高效液相色谱检测)；灵芝多糖的含量达36％(UV紫外分光检测)。
