Voacristine
Voacristine is a indole alkaloid occurring in ''Voacanga'' and ''Tabernaemontana'' genus. It is also an iboga type alkaloid. Chemistry Its structure is almost similar to voacangine, an alkaloid used in semi-synthesis of ibogaine. Compared to voacangine, it has an extra O-atom. When it is degraded, iboxygaine and ibogaine are formed. Sources Voacristine is found in multiple species of ''Tabernaemontana'' some of which are Tabernaemontana divaricata, Tabernaemontana heyneana, Tabernaemontana ventricosa and in Voacanga africana. See also * Heyneanine * Voacamine * Vobasine Vobasine is a naturally occurring monoterpene indole alkaloid found in several species in the genus ''Tabernaemontana'' including ''Tabernaemontana divaricata''.

Tabernaemontana Divaricata
''Tabernaemontana divaricata'', commonly called pinwheel flower, crape jasmine, East India rosebay, and Nero's crown, is an evergreen shrub or small tree native to South Asia, Southeast Asia and China. 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. Description The plant generally grows to a height of and is dichotomously branched. The large shiny leaves are deep green and about in length and in width. The waxy blossoms are found in small clusters on the stem tips. The (single) flowers have the characteristic 'pinwheel' shape also seen in other genera in the family Apocynaceae such as ''Vinca'' and ''Nerium''. Both single and double-flowered forms are cultivated, the flowers of both forms being white. The plant blooms in spring but flowers appear sporadically all year. The flowers have a pleasing fragrance. More than 66 alkaloids are found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Voacamine
Voacamine, also known under the older names voacanginine and vocamine, is a naturally occurring dimeric indole alkaloid of the secologanin type, found in a number of plants, including ''Voacanga africana'' and ''Tabernaemontana divaricata''. It is approved for use as an antimalarial drug in several African countries. Voacamine exhibits cannabinoid CB1 receptor antagonistic activity. Chemistry Structure There is considerable confusion about the absolute stereochemical configuration of voacamine and the originally published absolute structure had to be later revised. It has an ibogaine unit joined with vobasine unit. Adverse Effect Voacamine can cause hypertension in high dose.

''Voacanga africana'' is a small tree native to tropical Africa belonging to the family Apocynaceae that grows to in height and bears leaves that are up to in length. The yellow or white flowers are succeeded by paired, follicular, dehiscent fruit with a mottled green exocarp and a pulpy, yellow mesocarp surrounding the seeds. The plant contains alkaloids acting as CNS depressants and hypotensives Description ''Voacanga africana'' is a small tree up to tall with a spreading crown. The leaves are in opposite pairs, dark glossy green above and paler green below. The white or yellow flowers are in small bunches borne either in leaf axils or at the end of shoots. The spherical, dark green fruits, dappled with paler green, grow usually in pairs and contain seeds embedded in a yellow pulp. History ''Voacanga africana'' was named by botanist Otto Stapf in 1894 after he received a type specimen from George Scott-Elliot, who had been participating in the Sierra Leone Boundary Commi ...

Tabernaemontana Heyneana
''Tabernaemontana alternifolia'' is a species of plant in the family Apocynaceae. It is endemic to India. Taxonomy The name ''Tabernaemontana heyneana'' Wall. has often been used for this species, and a proposal was made to conserve that name so that it would be used instead of ''T. alternifolia''. Arguments made for conservation were that the type of the species was not a specimen but an illustration, and that the plant has opposite leaves In botany, phyllotaxis () or phyllotaxy is the arrangement of leaves on a plant stem. Phyllotactic spirals form a distinctive class of patterns in nature. Leaf arrangement The basic arrangements of leaves on a stem are opposite and alternat ..., not alternate leaves as ''alternifolia'' implies. However, the proposal was rejected, and the correct name of this species is the original name, ''T. alternifolia''.

Tabernaemontana
''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. The cultivar '' T. divaricata'' cv. 'Plena', with doubled-petaled flowers, is a popular houseplant. Some members of the genus ''Tabernaemontana'' are used as additives to some versions of the psychedelic drink ayahuasca; the genus is known to contain ibogaine (e.g. in bëcchëte, ''T. undulata''), conolidine (present in minor concentration in ''T. divaricata'') and voacangine ('' T. alba'', '' T. arborea'', '' T. africana'').

Ibogaine
Ibogaine is a naturally occurring psychoactive substance found in plants in the family Apocynaceae such as ''Tabernanthe iboga'', ''Voacanga africana'', and ''Tabernaemontana undulata''. It is a psychedelic with dissociative properties. Preliminary research indicates that it may help counter drug addiction. Its use has been associated with serious side effects and death. Between the years 1990 and 2008, a total of 19 fatalities temporally associated with the ingestion of ibogaine were reported, from which six subjects died of acute heart failure or cardiopulmonary arrest. The total number of subjects who have used it without major side effects during this period remains unknown. It is used as an alternative medicine treatment for drug addiction in some countries. Its prohibition in other countries has slowed scientific research. Ibogaine is also used to facilitate psychological introspection and spiritual exploration. Various derivatives of ibogaine designed to lack psychedel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
