The color antitriplet triquark qqq is considered as a compact component in the tetraquark structure cqqq of exotic Ds mesons. We discuss the mass spectrum and the flavor mixing of the triquarks by using the instanton induced interaction and the one-gluon exchange potentials. As a characteristic property of the triquark, we investigate the isospin violation. It is shown that the flavor 3 (isosinglet) and 6 (isotriplet) states may be strongly mixed and then are identified with Ds(2632).
