Abstract: Four new monoterpenoid bisindole alkaloids, flabellipparicine (1), 19,20-dihydrovobparicine (2), 10'-demethoxy-19,20-dihydrovobatensine D (3), and 3'-(2-oxopropyl)ervahanine A (4), and 10 known monoterpenoid indole alkaloids were isolated from the stems of Tabernaemontana divaricata. All structures were elucidated based… read more here.
