Nogueira, 36, returned to the cage on Saturday after nearly a year-long layoff due to an arm injury he sustained in a loss to Frank Mir in December. He submitted Dave Herman in the second round via armbar.
When asked if the win was possibly a good opportunity to step away on a high note, Nogueira smiled and answered he has plenty left.
"I still can fight," Nogueira said. "I feel amazing and I'm still hungry. I feel good physically. I'm very happy to be a part of the co-main event in Brazil and I want to be back fighting in Brazil next year or anywhere (UFC president Dana White) puts me."
Injuries have limited Nogueira (34-7-1) to just five appearances in the last three years. He underwent hip surgery in 2010 and came back strong with a knockout win against Brendan Schaub at UFC 134 in Brazil.
White praised the former Pride champion for his win over the athletic Herman, saying the veteran heavyweight, "blows my mind."
"Dave Herman is a monster," White said. "He's a big athletic guy and I thought it was going to be a rough night for Nog.
"The guy is a warhorse. He's fought all the best in the world. I told him when he came out, I'm honored to have you here fighting in the UFC. He's the nicest guy in the world, he's been incredibly successful and I couldn't be happier for him."
