Table 1 Total polyphenol and flavonoid contents of Portulaca oleracea L. extracts with different extraction solvent (mg/g)

Extraction solvent	Total polyphenol (mg GAE/g)1)	Total flavonoid (mg QE/g)1)
Water	15.03±0.032)	2.18±0.21
Ethanol	21.08±0.03*3)	5.45±0.76*

Total polyphenol and flavonoid contents are expressed as gallic acid equivalents (GAE) and quercetin equivalent (QE), respectively.
Each value is mean±SD of ≥3 determinations.
^*Means within same column are significantly different by student’s t-teat (p<0.05).
