“…Ziziphus species can grow either as trees and shrubs or exclusively as small shrubs or bushes 24) . Previous phytochemical studies on the different species of the genus Zizyphus led to the isolation and characterization of cyclopeptide alkaloids, flavonoids, sterols, tannins, and triterpenoid saponins 25) . Saponins are generally known as non-volatile, surface active compounds that are a structurally diverse class of compounds occurring in many plant species, which are characterized by a skeleton derived of the 30-carbon precursor oxidosqualene to which glycosyl residues are attached.…”

A fundamental chemical enhanced oil recovery (EOR) process is surfactant flooding in which the key mechanism is to reduce interfacial tension between oil and the displacing fluid and hence mobilizing the trapped oil. Surfactant loss by adsorption is one of the most important criteria that governs the economics of the surfactant flooding methods. In addition to this, detrimental effects and high price of currently used surfactants cause EOR process so expensive and unfeasible. This study is aimed to introduce a novel kind of plant based surfactant which is extracted from Zizyphus Spina-Christi tree. In addition, equilibrium adsorption behavior of this novel biosurfactant in aqueous solution on crushed reservoir rocks is presented. A conductivity technique was used to assess the critical micelle concentration (CMC) value in the aqueous phase. Batch experiments were used to understand the effect of adsorbent dose on sorption efficiency as well. Four adsorption models were also employed to make a quantitative description of equilibrium adsorption behavior of surfactant solution. For evaluating the ability of this novel biosurfactant on the surface properties, IFT values of Saponin solution were compared to those of commonly used chemical surfactants in petroleum industry. It is shown that availability and the low cost of the Zizyphus Spina-Christi extract in comparison to common chemical surfactants in petroleum industry make it economically viable for surfactant flooding.

“…Accordingly, The MIC values showed that the lowest level of antibacterial agent from the fruit extract of Ziziphus spina-christi that inhibit the growth of bacteria was ranging between (50-100 mg/ml). (Pawlowska et al, 2009), it was also reported that fruits of Ziziphus spina-christi have good antioxidant and anti-inflammatry effects and it was rich in bioactive phytochemicals such as tannins, steroids, flavonoids, alkaloids, glycosides and terpenoids (Alhakmani et al, 2014).…”

The aim of this review is to report the medicinal plants which have anti- fibrotic effect characterized in different studies. They are summarized which include name of the plants, part used, liver fibrosis model, fraction of plant used and observations. The medicinal plants play an important role in treatment and prevention of liver fibrosis through different physiological mechanism. The effects of medicinal plant may delay the development of liver fibrosis and have potential to reverse or degrade the accumulation of extra cellular matrix. Four different databases are used and 18 plants are included which have the potential for reversal of liver fibrosis. There are also few more plants but they are not characterized well in literature.
