ABSTRACT
Introduction: plants growing in deserts require special characteristics to survive under the extreme conditions of these regions. Inside these groups of plants are the genus
Pergularia, Hammada and
Rhus having a great versatility of medical
uses. Investigations about chemical composition and biological activities of these genuses are limited.
Objective: to determine the preliminary chemical composition of extracts from different polarity of
Pergularia tomentosa L. (
Apocynaceae),
Hammada scoparia (
Amaranthaceae) and
Rhus tripartita L. (
Anarcadiaceae).
Methods: plant materials used were the leaves and branches of the species. At the time of collection there was not flowering or fruiting in these plants. Extraction
procedure was carried out by maceration with methanol. From this extract preliminary fractionation was done using solvents with different polarity: hexane, ethyl acetate, methanol and buthanol. All these fractions were phytochemical screened.
Results: the secondary metabolites found in the preliminary identification of the three species were: alkaloids, reducing sugars, compounds with lactone groups and phenolic compounds.
Conclusions: in the three species, the methanolics fractions showed the most variety of secondary metabolites.
