Table 2. Total polyphenol and flavonoid contents of Opuntia spp. fruits extracts
| Fruits name | Total polyphenol (mg GAE/g)1) | Total Flavonoid (mg QE/g)1) |
| O. ficus-indica | 17.07±0.082) | 8.65±0.08 |
| O. humifusa | 9.41±0.14*3) | 2.03±0.08* |
1)Total polyphenol and flavonoid contents are expressed as gallic acid equivalents (GAE) and quercetin equivalent (QE), respectively.
2)Each value is mean±SD of ≥3 determinations.
3)*Means within same column are significantly different by Student's t-teat (p<0.05).
