The invention discloses a supercritical CO2 extraction method of effective components in bamboo fungus spores. According to the method, the bamboo fungus spores are put in an extraction kettle; CO2 is introduced in the supercritical state; and the temperature is 35-50 DEG C, the pressure is 20-50 MPa and the time is 1-5h; bamboo fungus spore extractive containing CO2 fluid flowing from the extraction kettle enters a separation kettle; decompressed CO2 outflows from the upper part of the separation kettle; and the oily and paste bamboo fungus spore extractive outflows from the lower part of a decompression separator. By adopting the method disclosed by the invention, the solubility of a solute in the supercritical fluid can be increased; furthermore, the polarity of an extracted material is increased; therefore, effective components in the bamboo fungus spores, such as terpenes, flavones and the like, are sufficiently extracted; the extraction rate is increased; contents of the effective components in the extr
