The 26-year-old Gambian sprinter began the race very well as she took the lead with Beatrice Masilingi right behind her before Mboma finished above them in the final pacing.
Mboma won the women's 200m race with a timing of 22.67 seconds ahead of Gina Bass who came second with a timing of 22.76 seconds. Mboma's compatriot Beatrice Masilingi won the bronze medal with a timing of 22.82 seconds.
Gold winner, Mboma of Namibia set a new personal best, while she also set a new record for the meeting, after breaking the previous record of 22.74 seconds held by Stephanie Durst of the United States in 2007.
The Namibians performance will raise their international profiles as they prepare for the Olympics Games next month.
Tubakuta-born sprinter Gina Bass is ranked third in African and 21st in the world with a timing of 22.62, while Mboma has now moved up to 26th position, and Masilingi to 29th position.
