Seven new steroids, GN70-153E (1), GN70-153F (2), GN70-153I (3), GN70-272F (4), GN70-272I (5), GN70-272L (6), and GN70-272L (7), were isolated from the Formosan soft coral Clavularia viridis by chromatographic separation of the EtOAc layer which was obstained from crude extraction in hexane¡ÐAcetone, 100% Acetone, Acetone¡ÐMeOH and 100% MeOH then partitioned between EtOAc and H2O. Their structures were determined based on the results of several kinds of spectroscopic analyses and HRESI-MS. Compounds 1-7 exhibited cyctotoxicity against HT-29 and P-388 cell lines in vitro.
