The third seeded Indian will now face Thailand's Kantaphon Wangcharoen tomorrow.
However, it was curtains for Sourabh Verma and Sai Uttejitha Rao Chukka in men's and women's singles competition.
While 12th seeded Sourabh fought hard before going down narrowly 16-21 25-23 11-21 to fifth seeded Brice Leverdez of France, Sai Uttejitha Rao lost 15-21 17-21 to Pattarasuda Chaiwan of Thailand.
In the second game, Zulkarnain had taken a 9-7 lead but Praneeth erased the deficit and marched ahead to close the door on the Malaysian in the 41-minute clash.
