Abstract
This study aims to explore the phytochemically bioactive compounds of three Sudanese
Tribulus species. Threewild species of Tribulus; T. terrestris, T.longipetalous and
T.pentandrus,were collected from KhartoumState. Their bioactive compounds were extracted by
ethanol, from their roots, aerial parts, and fruits. Gas-Chromatography-Mass Spectroscopy (GCMS)
was used for phytochemical analysis of their bioactive compounds.In T. terrestris different
compounds (20 from roots), (27 from aerial parts) & (29 from fruits) were identified by GC/MS.
Six classes of chemical compounds were found; sugars, fatty acids, terpenes, steroids, alkanes
and alcohols. Major components were sucrose (28.72%) in roots and 4-O-methyl-mannose in
aerial parts (49.60%) and in fruits (43.66%).
In T.longipetalous many compounds were identified; 23 from roots, 20 from aerial parts, and
29 from fruits. These compounds were classified into four groups; Sugars, fatty acids, terpenes
alcohols. The most commonly detected compound was 4-O-methyl mannose; 73.11% (in roots),
43.24% (in aerial parts) and 35.75% (in fruits). In T.pentandrus more compounds were
identified, 31 (roots), 31 (aerial parts) and 42 from fruits. These compounds were grouped into
eight classes; sugars, fatty acids, terpenes, steroids, alkanes, alcohols, steroidal sapogenins and
alkaloids. The major component also was 4-O-methylmannose 47.86 % (in roots), 44.75 % (in
aerial parts) and 55.05 % (in fruits).The most commonly found classes of compounds in the three
Tribulus species were; sugars, fatty acids, terpenes, steroids and alcohols.
The major compound found in all parts of the three Tribulus species was 4-O-methylmannose.
In addition other compounds were identified from T.pentandrus
