The Lady Tigers (19-4, 7-2 SEC) were led by Doneeka Hodges' 22 points and Seimone Augustus' 20, while Temeka Johnson tied her own school record with 15 assists to go with 14 points, Wendlyn Jones added 13 points and Hanna Biernacka had 12.
Gunter, absent from her eighth game for medical reasons, became just the third coach in women's basketball history to reach the milestone. She joins Tennessee's Pat Summitt and Texas' Jody Conradt.
"It's wonderful," LSU associate coach Pokey Chatman said about Gunter's milestone victory. "It is special to me because I have been here with her for so long. We always joke about why she reached 700 and it is because she has been doing this for a long time and she's done it really well."
Gunter, who is in her 40th season as a collegiate head coach, has been on the LSU sidelines for 22 years and has 434 wins as Lady Tigers head coach.
LSU and Arkansas (15-8, 3-6 SEC) battled tough in the first 20 minutes with the Lady Tigers taking a 36-32 lead into the locker room at the half. LSU then came out in the second half and put up 56 points on 21-30 shooting for a 70.0 percent clip.
"The most rewarding part of this victory was effort and execution," Chatman said. "Early in the game the effort was there, but the execution was not, but as the game progressed, the effort stayed the same and the execution was there."
