Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.
Tabernaemontana is a genus of flowering plants in the family Apocynaceae. It has a pan-tropical distribution, found in Asia, Africa, Australia, North America, South America, and a wide assortment of oceanic islands. These plants are evergreen shrubs and small trees growing to 1–15 m tall. The leaves are opposite, 3–25 cm long, with milky sap; hence it is one of the diverse plant genera commonly called "milkwood". The flowers are fragrant, white, 1–5 cm in diameter.
Voacangine is an alkaloid found predominantly in the root bark of the Voacanga africana tree, as well as in other plants such as Tabernanthe iboga, Tabernaemontana africana, Trachelospermum jasminoides, Tabernaemontana_divaricata and Ervatamia yunnanensis. It is an iboga alkaloid which commonly serves as a precursor for the semi-synthesis of ibogaine. It has been demonstrated in animals to have similar anti-addictive properties to ibogaine itself. It also potentiates the effects of barbiturates. Under UV-A and UV-B light its crystals fluoresce blue-green, and it is soluble in ethanol.

Tabernaemontana divaricata commonly called pinwheel flower, crape jasmine, East India rosebay and Nero's crown is an evergreen shrub native to South Asia and now cultivated throughout South East Asia and the warmer regions of continental Asia. In zones where it is not hardy it is grown as a house/glasshouse plant for its attractive flowers and foliage. The stem exudes a milky latex when broken, whence the name milk flower.

Tabernaemontana pandacaqui, known as windmill bush and banana bush, is a species of plant in the dogbane family Apocynaceae.

Apparicine is a monoterpenoid indole alkaloid. It is named after Apparicio Duarte, a Brazilian botanist who studied the Aspidosperma species from which apparicine was first isolated. It was the first member of the vallesamine group of alkaloids to be isolated and have its structure established, which was first published in 1965. It has also been known by the synonyms gomezine, pericalline, and tabernoschizine.
Vobasine is a naturally occurring monoterpene indole alkaloid found in several species in the genus Tabernaemontana including Tabernaemontana divaricata.
