| Summary: | Three new meliacarpinin-type limonoids, toosendanes A–C (1–3), along with three, known meliacarpinins (4–6) were isolated from the bark of Melia toosendan. Their structures, along with their absolute configurations, were elucidated, based on detailed analyses. These included HRESIMS and 1D/2D-NMR, modified Mosher’s method, and electronic circular dichroism (ECD). Limonoids 2 and 3 showed moderate inhibitory activity on LPS-activated, RAW 264.7 macrophages. |
