Summury: A new dichlorinated cyclic penta-peptide, asterin, has been isolated from the plant Aster &ztaricI(s L.f. (Cotqosime), and its structure has also been elucidated on the basis of its spectral data coupled with some chemical evidences. From a view point of biological activity, many structura
