---|---|---|---|---|
CE | 4.66 ± 0.14* | 2.10 ± 0.06# | 291.56 ± 3.25 | 871.75 ± 10.41 |

BHT | 4.68 ± 0.03 | 5.07 ± 0.19 | – | – |
The values are expressed as mean ± SEM, n = 3. CE, AA, BHT were abbreviations of C. cainito extract, ascorbic acid and butylated hydroxytoluene, respectively
*P < 0.05 compared with AA; #P < 0.05 compared with BHT by one-way ANOVA followed by Student-Newman-Keuls as post hoc test
