The invention discloses a belt-cyclodextrin matrix solid phase micro extraction coating and an extraction head, relating to the trace analyzing field of volatile and semi-volatile organic compounds in foods, environment and biological samples. The solid phase micro extraction coating comprises belt-cyclodextrin and polydimethylsiloxane which are mutually combined; the extraction head is composed of quartz fibers and a solid-phase micro-extraction coating on the surface of quartz fibers. In the belt-cyclodextrin matrix solid phase micro extraction coating, the belt-cyclodextrin and the polydimethylsiloxane are utilized as solid-phase micro-extraction coating materials, and the special cavity structure of the combined belt-cyclodextrin and polydimethylsiloxane is used to realize inner hydrophobicity and external hydrophile, thus the adsorbability to the polar materials is improved; by combining the nonpolarity of the polydimethylsiloxane, the selection range of the coating to the polarity of the adsorbed substances is expanded; and in addition, the belt-cyclodextrin matrix solid phase micro extraction coating is especially applied to the detection on organic matters, such as phenolsand the like in aroma combination and environmental water samples and residual pesticides in fruits and vegetables.
