Dutee competed the 100m heats within an hour of reaching Taiwan from Beijing and five hours later ran the finals which she won in 11.50secs to bag the gold.
Her timing was far below the Olympics qualification standard of 11.32 secs.
Long jumper Ankit Sharma leapt 7.67m on his last attempt to also seal a gold medal.
Dutee was part of the national record breaking women's 4x100m relay quartet which finished fourth in the IAAF World Challenge event in Beijing yesterday and she few from the Chinese capital to Taiwan where she reached two hours before the start of her event.

"Poor girl, she had to compete after a tiring flight and within one hour," Ramesh added.
Dutee will also run in the women's 4x100m relay finals tomorrow. Ramesh also said that his ward was disappointed as she could not compete in the individual 100m sprint event in Beijing as she was told to withdraw at the last minute despite her name was in the start list.
It's learnt that the organisers kept Dutee as a reserve runner on the condition that she would compete in case another athlete withdraws from the race.
Dutee had gone to Beijing with a big hope that she will be able to qualify for Rio Olympics by competing with stronger rivals. She had missed the Rio qualifying standards by one-hundredth of a second in the Federation Cup National Athletics Championships in New Delhi last month with a timing of 11.33secs.
Dutee will have two more events to try and qualify for the Olympics -- one each in Kazakhstan and Kyrgyzstan -- next month, besides the National Inter-State Championships in Hyderabad also next month.
