description

Abstract Two diterpenoids have been isolated from Scutellaria rubicunda subsp. linneana : (11 S ,13 S ,15 R and S , 16 R ,19 S )-6 α -acetoxy-19-tigloyloxy-2 α ,19;4 α ,18;11,16;15,16-tetraepoxy-neo-clerodan-15-ol (scutecyprol B) and (11 S ,13 S ,15 R and S , 16 R ,19 S )-6 α -acetoxy-2 α ,19;4 α ,18;11,16;15,16-tetra-epoxy-neo-cleroda-15,19,diol (scutalbin C). Both compounds were tested for antifeedant activity against larvae of some species of Lepidoptera. Scutecyprol B shows potent activity at 100 ppm.
