We study the genuine multipartite entanglement of arbitrary n-partite quantum states by representing density matrices in terms generalized Pauli operators. introduce a general framework for detecting and non full-separability with dimensions based on correlation tensors. Effective criterion is derived to verify entanglement. Detailed examples are given show that detects more than existing criteria.
