摘要
Phytochemical investigations on Tabernaemontana divaricata led to the isolation of seven undescribed monoterpenoid indole alkaloids,taberdicatines A-G(1-7).Taberdicatines A-C might be derived from Aspidosperma-type alkaloid,less skeletal carbons in 1-2 and an additional carbon in 3.Taberdicatines D-E(4-5)were attributed to Iboga alkaloids with enantiomeric skeleton,respectively.Alkaloid 3 could promote the neurite growth of mouse primary cortical neurons at the concentration of 5 pimol/L.
