These compounds were evaluated and compared with the antioxidant standards n-propyl gallate, BHT and á α-tocoferol.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2011-10-19T13:38:45Z No. of bitstreams: 1 a04v13s2.pdf: 42054 bytes, checksum: 8621aea98907826677ad3490b8d394b1 (MD5)Made available in DSpace on 2011-10-19T13:38:45Z (GMT).
