Storage Effect on Phenols and on the Antioxidant Activity of Extracts from Anemopsis californica and Inhibition of Elastase Enzyme

الملخص EN

The amount of total phenols and flavonoids and the antioxidant activity of leaf, stem, and rhizome methanolic extracts from a commonly consumed Anemopsis californica under different storage conditions were investigated.

Storage conditions were at 50, 25, 4, and −20°C, protected or not from light, during 180 days.

The inhibition of the elastase enzyme was also evaluated.

The results demonstrated that leaf, stem, and rhizome methanolic extracts of Anemopsis californica maintain approximately up to 97 and 95% stability in phenolic content and antioxidant activity, respectively, when stored during 60 days at −20°C in the dark.

Additionally, these extracts, principally from leaf and rhizome, showed an elastase inhibitory effect by 75 and 71.8%, respectively.

Therefore, this study provides the basis for further research on the anti-inflammatory activity.

On the other hand, Anemopsis californica could comprise a good alternative of use as antioxidant in foods.
