Identifying the polyphenolic compounds and antioxidant activity of Finola oilseed hemp

Identifying the polyphenolic compounds and antioxidant activity of Finola oilseed hemp2019.02.22

Researchers from the University of Messina in Italy have found a specific type of hemp that contains potent antioxidant properties. In their article, which appeared in Phytotherapy Research, they looked at the antioxidant activity of cold-pressed seed oil of finola hemp (Cannabis sativa L. ‘finola’), as well as the polyphenolic compounds present.


For the study, the team evaluated the antioxidant activity of both lipophilic (LF) and hydrophilic fractions (HF) of finola hempseed oil (FHSO).




Researchers used an HLPC analysis to determine the qualitative and quantitative composition of the phenolic fraction of FHSO.

The results revealed the FHSO has high antioxidative properties, based on the results of DPPH radical (146.76 mmol of TE/100 g oil) assay. In addition, an inhibited ??carotene bleaching showed that it quenched a chemically generated peroxyl radical in vitro and showed high ferrous ion chelating activity.


They also found that the reactivity of the hemp towards 2,2??azino?bis (3?ethylbenzothiazoline?6?sulfonic acid) radical cation and ferric?reducing antioxidant power values were 695.2 µmol of TE/100g oil and 3690.6 µmol of TE/100 g oil respectively.


The researchers noted that FHSO has potent antioxidant properties because of the number of phenolic compounds — in particular, flavonoids like flavanones, flavonols, flavanols, and isoflavones — present in the fractions.
