Alkana finished 0.13 ahead of Hungarian athlete Balazs Baji, the European Championships silver medallist, who took second position.
In the women's 400m hurdles, Wenda Nel gave a clear indication she was approaching her best form, taking a convincing win in 54.66 to clock an 'A' standard IAAF qualifying time for the IAAF World Championships in August.
She completed the race 0.76 clear of her nearest competitor, World Student Games champion Joanna Linkiewicz of Poland.
