Abstract

The fruit of date palm (Phoenix dactylifera L.) is well-known for its several health blessings and dietary values and its wonderful supply of phenolics compounds and holds relatively exquisite antioxidant capacity. Therefore, the goal of this study is to investigate the free radical scavenging efficiency of the five-date types Aseel, Kupro, Karbala Wari, Asul Khurmo and Gajar Wari cultivated in district Khairpur Mir’s. These date varieties were screened with the help of DPPH assay to evaluate their free radical scavenging efficiency in different solvents. From the statistics, it turned into scrutinize that each extract has interesting antioxidant functionality against free radicals. The methanolic extract has more potential to incline the free radicals. It was concluded that the date variety Asul Khumro is shown excellent activity because it possesses lowest IC50 value 17.823µg/mL, followed by Gajar Wari 20.679 µg/mL in methanolic solution while Kupro 20.937µg/mL in Methanol + Water solution then relaxation of different date varieties at their mature Tamar level. It is concluded from the results that all dates fruit varieties at their final mature stage holds higher antioxidant potency and indicated that these date fruits have natural antioxidants.

Highlights

The fruit of date palm (Phoenix dactylifera L.) is well-known for its several health blessings and dietary values and its wonderful supply of phenolics compounds and holds relatively exquisite antioxidant capacity
It's far pronounced from literature that Alligue possess the lowest EC50 Value 0.62 mg/ml followed via Deglet Nour (1.53 mg/ml), Kentichi (1.68 mg/ml) and khouet Kenta (1.96 mg/ml) cultivated in Tunisian through the DPPH method (Saafi, et al, 2009)
The capability of the methanolic extract of those dates to scavenge Free radicals (ABTS stands for 2,2'-azino-bis (3ethylbenzothiazoline-6-sulfonic acid and DPPH stands for 1,1-Diphenyl-2-picryl-hydrazyl) may be attributed to the presence of two principal types of antioxidant compounds (Saafi et al, 2009). It is evident from the report of Ahmed (-) that the date varieties, the EC50 values of Saudi Arabia date sorts turned into screened via DPPH assay and the result indicates that Ajwa variety suggests lowest EC50 value 2.90 mg/ml accompanied with the aid of Sukkari 4.30 mg/ml and Khalas 6.60 mg/ml in water extract and in alcoholic solution Ajwa 3.80 mg/ml possess lowest EC50 value Sukkari 4.10 mg/ml and Khalas 9.10 mg/ml, the decrease the EC50, the higher the antioxidant capacity (Saleh, et al, 2011)

Summary

Introduction

The fruit of date palm (Phoenix dactylifera L.) is well-known for its several health blessings and dietary values and its wonderful supply of phenolics compounds and holds relatively exquisite antioxidant capacity. The capability of the methanolic extract of those dates to scavenge Free radicals (ABTS stands for 2,2'-azino-bis (3ethylbenzothiazoline-6-sulfonic acid and DPPH stands for 1,1-Diphenyl-2-picryl-hydrazyl) may be attributed to the presence of two principal types of antioxidant compounds (Saafi et al, 2009) It is evident from the report of Ahmed (-) that the date varieties, the EC50 (half maximal effective concentration) values of Saudi Arabia date sorts turned into screened via DPPH assay and the result indicates that Ajwa variety suggests lowest EC50 value 2.90 mg/ml accompanied with the aid of Sukkari 4.30 mg/ml and Khalas 6.60 mg/ml in water extract and in alcoholic solution Ajwa 3.80 mg/ml possess lowest EC50 value Sukkari 4.10 mg/ml and Khalas 9.10 mg/ml, the decrease the EC50, the higher the antioxidant capacity (Saleh, et al, 2011). The intention of this work is to know the antioxidant potency of 5 date palm fruits extracts at their mature (Tamar an Arabic word to show the mature or ripped level of dates) level with water, methanol, and the mixture of water: methanol (50:50) in step with the technique described by using Blois (1958)
