ANTILIPOPEROXIDATIVE EFFECT OF THREE EDIBLE PLANTS EXTRACTS: VISCUM ALBUM, ARUM DIOSCORIDIS AND EMINIUM SPICULATUM

Abstract

In this study, evaluation of the antilipoperoxidative activity of the aqueous, boiled and nonboiled, and methanolic extracts of Viscum album (leaves, stems and fruits), Arum dioscoridis and Eminium spiculatum leaves against lipid peroxidation (LPO) induced by a rat liver homogenate model was undertaken. LPO was induced by ascorbate/FeCl2 mixture and evaluated using thiobarbituric acid reactive species assay. Nonboiled aqueous extracts exhibited the highest LPO inhibition percent, followed by methanolic and boiled aqueous extracts. Moreover, LPO inhibition percent was dose dependent, where 1.65 × 10−2 mg/mL caused the highest inhibition percent in all aqueous extracts. Aqueous extracts of A. dioscoridis and E. spiculatum exhibited significantly lower LPO inhibition percents than V. album parts, which were comparable to those obtained from the aerial parts of the positive control (Rosmarinus officinalis). Antioxidant capacity was the highest in V. album stems and leaves in all methods of extraction, and was comparable to the R. officinalis results, while V. album fruits, A. dioscoridis and E. spiculatum leaves possessed approximately 50% of antioxidant capacity using all methods of extractions. These results suggest that these plants can be used as a condiment during food processing, to improve the quality, enhance flavor, increase the nutritional value and increase the shelf life of processed food. PRACTICAL APPLICATIONS Viscum album, Arum Dioscoridis and Eminium Spiculatum can be used to improve the quality, boost the nutritional value and prolong the shelf life of processed food.

Hydroalcoholic extract of Arum orientale ameliorates myocardial infarction induced by isoproterenol in rats

“…Our results demonstrated that only moderate doses of hydroalcoholic extract of A.orientale decreased serum MDA levels that shows dose independent effects. In line with our results, Janakat & Al-Thnaibat [38] showed that aqueous extracts of A. dioscoridis has anti-lipid peroxidation activity. These findings could be due to presence of flavonoids and phenolic compounds in structure of Arum species because these compounds have radical scavenging and antioxidant activities [11].…”

Screening of Phytochemicals and Antioxidant Activity of Arum Dioscoridis Seeds

“…Ido Izhaki (1998) determined amino acid and protein content of A. dioscoridis grown in East Mediterranean. Janakat and Al‐Thnaibat (2008) studied on antilipoperoxidative activity of the methanolic extract of A. dioscoridis leaves against lipid peroxidation induced by a rat liver homogenate model. They studied lipid peroxidation of their leaves on rat and have reported that A. dioscoridis may be used in food processing because of their high antioxidant capacity leading to antilipoperoxidative effect (Williams et al .…”

Chemical Composition of Amurca Generated from Jordanian Olive Oil

“…Methanolic extract of amurca caused significant LPO inhibition (96.1%), while freshly pressed olive oil caused 53.1% LPO inhibition. This can be attributed to high total phenolic compounds and antioxidant activity that inhibits MDA formation [24,25]. Figure 2 shows the chromatogram of phenolic compounds of amurca extract.…”
