Abstract
A phytochemical and directional investigation was carried out on the leaves of Callicarpa nudiflora. Various separation methods including silica gel, sephadex LH-20, medium pressure liquid chromatography (MPLC), preparative thin-layer chromatography (p-TLC) and preparative high performance liquid chromatography (p-HPLC) were used to isolate 10 compounds. The comprehensive structural elucidation of five novel monoterpenoids (1-5) was achieved through multi-spectroscopic analyses, and advanced quantum mechanical electronic circular dichroism (ECD) calculations. Furthermore, the anti-inflammatory activity of the identified compounds was assessed.
