Phytochemical Characterization, In Vitro Antioxidant Activity, and Quantitative Analysis by Micellar Electrokinetic Chromatography of Hawthorn (Crataegus pubescens) Fruit

Table 1

Phytochemical characterization and content of free polyphenolic compounds in Crataegus pubescens fruits.

Group/compound	Concentration
Total carbohydrates (g/100 g extract)	69.8 ± 1.61
Total phenolics (mg gallic acid equivalent/g fruit dry)	168.6 ± 0.9
Total flavonoids (mg equivalents quercetin/g dry fruit)	55.89 ± 0.11
Proanthocyanidins (mg cyanidin/100 g dry fruit)	84.57 ± 1.43
(−)-Epicatechin (mg/100 mg dry fruit)	4.32 ± 0.11
(+)-Catechin (mg/100 mg dry fruit)	9.17 ± 0.20
Chlorogenic acid (mg/100 mg dry fruit)	5.60 ± 0.24

The response factor for estimation of the phenolic content was from the calibration curve using MEKC. The results are shown as the mean ± SD (n = 3).
