Antioxidant activity of methanolic extracts from three coriander (Coriandrum sativum L.) fruit varieties

Coriander seeds processing: Sequential extraction of non-polar and polar fractions using supercritical carbon dioxide extraction and ultrasound-assisted extraction

“…TF/TP ratio was similar in all extracts (50-60%), however, in case of water extract obtain from fraction 3, this ratio was surprisingly high (>90%). TF of certain samples obtained in this work was significantly lower comparing to TF obtained in methanolic extracts by Msaada et al (2013) (203 -207 mg CE/100 g CS). These authors obtained twice higher TF comparing to TP, which is hardly explainable since flavonoid compounds are subgroup of polyphenols, and TF should always be lower than TP.…”

“…Results of quantified individual polyphenols obtained in this work were consisted with results given in the study of Msaada et al (2013), who performed HPLC analysis on methanolic extracts of three coriander varieties. They obtained values of 1.41-14.78 mg/100 g CS, 0.67-8.76 mg/100 g CS and 0.51-8.36 mg/100 g CS for contents of chlorogenic, caffeic and rosmarinic acids, respectively, while the content of rutin was between 1.10 and 13.96 mg/100 g CS, additionally confirming obtained content of identified compounds in this study.…”

“…TP obtained from fraction 3 was 222.08 and 308.55 mg GAE/100 g ECS for ethanolic and water extract, respectively. Msaada et al (2013) determined TP, TF and antioxidant activity from methanolic coriander extracts, where TP varied from 94 to 109 mg GAE/100 g CS, depending on coriander variety. These results are lower than TP obtained in this work by ethanolic and water UAE (110.53 -308.55 mg GAE/100 g ECS).…”

“…Antioxidant activity of ethanolic extracts of exhausted coriander seeds (24.78 µg/mL) were consisted with antioxidant activity determined in methanolic extracts from three coriander seed varieties (27 -36 µg/mL), previously reported byMsaada et al (2013).…”

Study on Total Phenolic, Flavonoid Contents and Antioxidant Activity of Water Extract of Endemic Plant Satureja Hortensis Leaves

“…In fact, it has been found that antioxidant molecules such as polyphenols, flavonoids, and tannins reduce and discolor DPPH due to their hydrogen donating ability (Msaada et al, 2014). These kinds of extracts have superior control effect on free radicals in comparison with non-polar ones.…”
