title: New dicyclopeptides from Dianthus chinensis.
abstract: One new dicyclopeptide cyclo-(L-N-methyl Glu-L-N-methyl Glu) (1), together with one new natural dicyclopeptide cyclo-(L-methyl Glu ester-L-methyl Glu ester) (2), and two known dicyclopeptides cyclo-(L-methyl Glu ester-L-Glu) (3), and cyclo-(L-Glu-L-Glu) (4), were isolated from the aerial parts of Dianthus chinensis L. Their structures were determined by spectroscopic analyses and chemical methods.
