title: Two new rearranged abietane diterpenoids from tropical Isodon coetsa.
abstract: Two new rearranged abietane diterpenoids, sincoetsin A (1) and sincoetsin B (2), were isolated from the aerial part of Isodon coetsa (Buth-Ham ex D.Don) Hara collected in Singapore, and their structures were determined by spectroscopic methods, especially 2D NMR techniques.
