Abstract
New cyclic peptides 1 and 2 were isolated from the endophytic fungus #2221 from Castaniopsis fissa on the south China sea coast. By 2D NMR methods and chiral HPLC technique, their structures were elucidated as cyclo (L-Val-L-Leu-L-Val-L-Leu) and cyclo(L-Leu-L-Ala-LLeu-L-Ala), respectively.
