Abstract

  1. A phytochemical screening of Cestrum species C. aurantiacum, C. diurnum and C. purpureum was carried out revealing the presence of steroidal saponins, sterols, catechol tannins, carbohydrates and flavonoids. Steroidal alkaloids are found only in C. purpureum.

  2. Sucrose, glucose and fructose were the only sugars detectable in the three species.

  3. The unsaponifiable matters of lipids of the three species were found to contain β–amyrin and β–sitosterol. The fatty acids were identified by GLC as myristic, palmitic, stearic, oleic and linoleic. The percentage of these acids in the different species revealed quantitative differences.

  4. Ursolic acid was isolated only from C. diurnum.
