Steroids With Insecticidal Activity Against the Larvae of Diaphorina citri Kuwayama From Tinospora sagittata
Twelve steroids ( 1 − 12 ) including one undescribed and a new natural product were isolated from the roots of Tinospora sagittata . The chemical structures of those compounds were elucidated by spectroscopic methods, electronic circular dichroism (ECD) or single‐crystal x‐ray diffraction analysis. Notably, c...
