New cyclic peptides from Citrus medica var. sarcodactylis SWINGLE.

Two new cyclic peptides were isolated from the fruit peels of Citrus medica var. sarcodactylis SWINGLE. Their structures were elucidated as cyclo(-Gly-Asp-Leu-Thr-Val-Tyr-Phe-) and cyclo(-Gly-Leu-Pro-Trp-Leu-Ile-Ala-Ala-) by intensive two-dimensional (2D) NMR analysis and chemical evidence.
