Several indole alkaloids have been isolated from Tabernaemontana persicariifolia. The stem bark and root bark contain mainly the monomeric indole alkaloids dregamine and vobasine, and also some tubotaiwine, which occurs in the leaves as well. Dregamine shows convulsant and respiration-stimulant activities. It also inhibits muscular fatigue in vitro and in vivo. It is used in treatments of muscular and nervous asthenia, respiratory depression and type III poliovirus (HPV-3). Tubotaiwine has local analgesic activity. Vobasine exhibited little activity in general pharmacological screening tests. The bark also contains sterols, triterpenes and saponins[
