Description:
Six new labdane diterpenoids, leopersin C (1), 15-epi-leopersin C (2), leopersin D (3), leopersin E (4), leopersin F (5), and 7-epi-leopersin F (6) were isolated from the aerial parts of Leonurus persicus. Their structures were elucidated by extensive use of 1D and 2D homonuclear and heteronuclear shift-correlated 1H−13C-NMR spectroscopic methods. Leopersin C (1) and 15-epi-leopersin C (2) were obtained as a C-15 epimeric mixture, and their structures were elucidated on this basis.
