Beschreibung
This Rauwolfia alkaloid is found in the barks of R. serpentina and R. vomitora
and was originally given the name Reserpinine, this being altered to avoid
confusion with another alkaloid of the same name (q.v.). The base has [α]
17D - 99.2° (c 1.3, CHCI3). From chemical degradation and spectroscopic analysis,
the structure has been established as the 3:4: 5-trimethoxycinnamoyl ester of
reserpic acid.
Chemische Eigenschaften
white to cream powder
Verwenden
Rescinnamine occurs in the roots of a num ber of Rauwolfia species. Therapeutically, itis used as an antihypertensive agent.
Allgemeine Beschreibung
Odorless white to cream colored crystalline powder.
Air & Water Reaktionen

The neat material darkens slowly on exposure to light. In solution this occurs more rapidly. .
Health Hazard
The pharmacological properties of rescinnamine are similar to those of reserpine, butthe side effects are low. It acts as a sedativeand hypotensive. A dose of 0.25 mg/day mayproduce the effect of sleepiness in humans.Excessive doses may produce depression,nightmare, nausea, diarrhea, and hypotension.
LD50 value, oral (rats): 1000 mg/kg
The carcinogenicity of rescinnamine inanimals or humans is unknown.
