To evaluate the nutritional and functional value of  Sipunculus nudus , a rapid, simple and sensitive analytical method was developed using ultra-high performance liquid chromatography coupled with a triple quadrupole mass detection in multiple-reaction monitoring mode for the simultaneous quantitative determination of 25 free amino acids and 16 nucleosides and nucleobases in  S. nudus  within 20 min, which was confirmed to be reproducible and accurate. The limits of detection (LODs) and quantification (LOQs) were between 0.003–0.229 μg/mL and 0.008–0.763 μg/mL for the 41 analytes, respectively. The established method was applied to analyze 19 batches of  S. nudus  samples from four habitats with two different processing methods. The results showed that  S. nudus  contained a variety of free amino acids, nucleosides and nucleobases in sufficient quantity and reasonable proportion. They also demonstrated that the contents of these compounds in different parts of  S. nudus  were significantly discriminating, which were in the order: (highest) coelomic fluid > body wall > intestine (lowest). The method is simple and accurate, and could serve as a technical support for establishing quality control of  S. nudus  and other functional seafoods. Moreover, the research results also laid foundation for further exploitation and development of  S. nudus .
