- Abstract
The primary objective of this study was to valorized Vitex agnus-castus residues in terms of phenolic com-pounds. The effects of extraction time {30--360min), solid to liquid ratio (0.1-0.3 g>DryBiomass/mlsoivent), type of solvent and different tissue types (leave, roots and seeds) on total polyphenols, o-diphenols, total flavonoids and anthocyanins were evaluated. The highest total polyphenol (31.5 mgcaffekAcidEquivaient/gDryBiomass) and diphenol (12.4mgcaffeicAcidEquivaient/gDiyBiomass) contents were obtained from methanolic extract of leaves after 180 min using a solid/liquid ratio of 0.1 gDryBiomass/mlsoivent, while total flavonoids, reached a maximum value of 19.4 mgcatechinEquivaient/gDiyBiomass after 360 min under the same conditions. Roots of V. agnus-castus were found to be a good source of anthocyanins with the highest yield of 0.62mgMaividinEquivaient/gDryBiomass/mlsolvent using ethanol as a sol-vent (180min and 0.2gDryBiomass/mlSoivent). The maximum antiradical power (178.5 xlextract/|J.gDPPH) was exhibited by the methanolic leave extract obtained after 360 min at solid/liquid ratio of 0.3 gDryBiomass/mlSoivent.
