Let G be a finite (not necessarily abelian) group and let p = p(G) be the smallest prime number dividing vertical bar G vertical bar. We prove that d(G) <=vertical bar G vertical bar/p + 9p(2) 10p, where d(G) denotes the small Davenport constant of G which is defined as the maximal integer l such that there is a sequence over G of length l containing no nonempty one-product subsequence.
