This study was designed to put into consideration both the in vitro and in vivo investigations on Talinum triangulare (Tt), an herbaceous perennial plant that is a native of tropical America and one of the most important vegetables in Nigeria.
Total phenolic contents in (mg GAE/100 g), flavonoid contents, the ferric reducing antioxidant properties (FRAP), 2, 2-diphenyl-1-picrylhydrazyl (DPPH), hydroxyl free radical scavenging ability (OH-) and iron chelating ability were carried out in vivo using standard described methods while GSH, GPx, catalase and SOD were determined in vivo using standard described methods.
In the three different solvents extraction of T. triangulare that were studied in vitro, it was noted that ethyl acetate and ethanolic fractions of T. triangulare showed potent antioxidant activity against DPPH and iron chelating property with high phenolic content except Hydroxyl free radical scavenging ability that showed highest value in the aqueous extract, while the Reduced GSH indicated the highest in the parameter determined in vivo.
The antioxidant properties showed in this solvent extractable component probably could have been the basis for the enhanced activities of antioxidant enzymes at very lower dose in the examined tissue homogenates. Therefore, T. triangulare can thereby serve as a means of Preventing some of major degenerative diseases challenging Humans.
本研究旨在综合考虑对三角叶马齿苋(Talinum triangulare,Tt)的体外和体内研究。三角叶马齿苋是一种多年生草本植物,原产于热带美洲,是尼日利亚最重要的蔬菜之一。
采用标准描述方法在体内测定(mg GAE/100 g)总酚含量、黄酮含量、铁还原抗氧化能力(FRAP)、2,2-二苯基-1-苦基肼(DPPH)、羟基自由基清除能力(OH-)和铁螯合能力,同时采用标准描述方法在体内测定谷胱甘肽(GSH)、谷胱甘肽过氧化物酶(GPx)、过氧化氢酶和超氧化物歧化酶(SOD)。
在体外研究的三角叶马齿苋的三种不同溶剂提取物中,注意到三角叶马齿苋的乙酸乙酯和乙醇提取物对DPPH显示出强大的抗氧化活性和具有高酚含量的铁螯合特性,除了羟基自由基清除能力在水提取物中显示出最高值,而还原型谷胱甘肽在体内测定的参数中显示最高。
这种溶剂可提取成分中显示的抗氧化特性可能是在所检测的组织匀浆中极低剂量下抗氧化酶活性增强的基础。因此,三角叶马齿苋可以作为预防一些挑战人类的主要退行性疾病的一种手段。
