From the aerial part of Scutellaria discolor, eight new neoclerodane diterpenes (compounds 3,4,6,8,9,10,11 and 12) were isolated together with clerodin, dihydroclerodin-I, clerodin hemiacetal (14-hydro-15β-hydroxyclerodin), jodrellin A, scutaltisin, squalene, 24-methylenecycloartanol and a mixture of 3-epioleanolic acid and 3-epiursolic acid. The structures of new compounds were determined by spectroscopic and chemical methods as follows : 3,15β-ethoxy-14-hydroclerodin; 4,15α-ethoxy-14-hydroclerodin; 6,(6α)-19-O-acetyl-4,18 : 11,16 : 15,16-triepoxyneoclerodane-6,15,19-triol (6-O-deacetyl-14-hydro-15-hydroxyclerodin); 8,6α-O-acetyl-2,19 : 4,18 : 11,16 : 15,16-tetraepoxy-14-neoclerodene-6,19-diol (19-O-deacetyljodrellin A); 9,10,11,and 12,6α-O-acetyl-15β, 19β-di-O-ethyl-, 6α-O-acetyl-15α, 19β-di-O-ethyl-, 6α-O-acetyl-19β-O-ethyl- and 6α, 19-di-O-acetyl-2,19 : 4,18 : 11,16 : 15,16-tetraepoxyneoclerodane-6,15,19-triol, respectively.
