The effect of the plant parts (leaf, flower, stem and seed) on antioxidant activity, bioactive compounds, fatty acids and mineral contents of chaste (Vitex agnus-castus L.) plant

Abstract

Total phenolic and flavonoid amounts of the Vitex agnus-castus plant were displayed to be between 1146.43 (seed) and 1724.21 mgGAE/100 g (flower) to 4250.00 (seed) and 9264.29 mg/100 g (stem), respectively. Vitex agnus-castus parts contained total carotenoids ranging from 3.79 (flower) to 20.81 µg/g (leaf). In addition, Vitex agnus-castus parts contained total carotenoids ranging from 3.79 (flower) to 20.81 µg/g (leaf). Antioxidant activities of the parts of chaste plant changed between 18.39 (seed) and 19.05 mmol/kg (stem). Statistically significant differences were detected in quantities of phenolic constituents in Vitex agnus-castus plants depending on the plant parts (p < 0.05). Catechin and rutin quantities of the parts of chaste plant were displayed to be between 185.54 (leaf) and 311.60 mg/100 g (flower) to 137.39 (flower) and 217.77 mg/100 g (stem), respectively. Oleic and linoleic acid quantities of the oils of the chaste plant parts were characterized to be between 16.62 (leaf) and 17.72% (seed) to 37.68 (leaf) and 65.21% (seed), respectively. Chaste plant parts contained the highest amounts of Ca, followed by K, S, Mg, P, Fe, Mn, Zn, B and Cu in decreasing order. A significant diversity and variability was observed between the chemical properties of Chaste plant part extracts.
