We investigate genuine multipartite entanglement in general multipartite systems. Based on the norms of the correlation tensors of a multipartite state under various partitions, we present an analytical sufficient criterion for detecting the genuine four-partite entanglement. We show that our criterion can detect genuine entanglement by detailed example. The results are generalized to arbitrary multipartite systems.
