## Synopsis The strategy and tactics of conformational analysis of cyclic peptides in solution is demonstrated by the example of cyclo(-D-Pro-Phe-TPhe-TYp-Phe-). Spin-locked experiments like rotating frame nuclear Overhauser enhancement spectroscopy (ROESY), ROTO, and TOCSY are successfully applie

The solid and solution state conformation of yunnanin A, a cyclic heptapeptide, cyclo(-Gly-Tyr-Gly-Gly-Pro-Phe-Pro-), isolated from the roots of Stellariu yunnanensis were studied. The X-ray diffraction studies showed that the crystal of yunnanin A [orthorhombic form from a ethanol-methanol mixture,
