“…Different parts of this tree including fruits, leaves, galls, and resin have been used in folk medicine (Bozorgi et al, ). Leaves and fruits of P. atlantica constitute a good source of several bioactive compounds such as essential oils and polyphenols (Gourine et al, ; Peksel et al, ). Numerous experimental studies have focused on the composition of the oil extracted from the fruits (Guenane et al, ; Yousfi et al, , ).…”

This study aimed to determine the effect of the maturation degree on the chemical composition of Pistacia atlantica fruits oil. A total number of 21 samples of fruits at three stages of maturation (unripe, middle maturity, and ripe fruits) were used in this study. Thus, the fatty acid composition was studied; the percentage of the unsaponifiable matter (w/w) and its anti-DPPH (2,2-diphenyl-1picrylhydrazyl) activity were assessed. The total phenolic compound content was also evaluated. The obtained results indicated, for the first time, that unripe fruits oil was characterized by richness in linoleic acid (31.63% AE 3.64%), in unsaponifiable matter (9.29% AE 6.19% w/w), and in phenolic compounds (2.51 mg per 100 g oil). For ripe fruit oil, these values were similar to those of some seed oils (22.41% AE 3.66%, 2.98% AE 1.71% w/w, and 0.13 mg per 100 g oil, respectively). Data analysis by principal component analysis showed that linoleic acid percentage and the unsaponifiable fraction percentage could constitute good markers for these fruits. These two parameters associated with a high level of phenolic compounds seem to distinguish and value the oil of P. atlantica unripe fruits. Thus, the findings revealed that the unripe fruits, rich in bioactive molecules such as unsaturated fatty acids and phenolic compounds, would be the optimal stage of harvesting time. Based on this, we could integrate this natural bioresource in industrial applications.

“…Several works have revealed that plants constitute a major source of natural bioactive compounds, including essential oil [2,3]. Among these plants, P. atlantica has a great value because of the antioxidant activity of its extracts [4,5], the composition of its fruit oil [6,7], its flavonoid content [8] and its anti-cancer activities [9]. All these virtues explain its diverse uses by local populations.…”

Pistacia atlantica fruit oil has been used for a long time by local populations for culinary and medicinal purposes. In this study, the fatty acid composition and tocopherol content were determined in twelve samples of P. atlantica fruit oil at three stages of maturation (immature, intermediate maturity and mature) collected in three different sites from the region of Laghouat. The results indicated a significant difference between the oil of mature fruits (green and black) and the immature ones (light red), which were distinguished by richness in unsaturated fatty acids and tocopherols. The oil from fruits of intermediate maturity (dark red) seems to combine these properties with those of the mature group, including oil yields. Such data emphasize the value of this oil, which needs further investigation.

“…The most effective AChE inhibitory activity of the extracts of P. atlantica leaves has been reported by ethyl acetate and aqueous extracts, probably due to the high phenolic components in these substances [49]. The results of two studies in this domain demonstrated that the aqueous extract of P. atlantica leaves possessed remarkable AChE inhibitory activity with an IC 50 of 0.87 ± 0.55 µg/mL [43] and 58.05 ± 0.12 µg/mL [50], respectively. It should be noted that P. atlantica consists of large amounts of phenolic compounds, possibly associated with the strong AChE inhibitory effect [43,50].…”

Pistacia Genus as a Potential Source of Neuroprotective Natural Products

Neuroprotective agents are able to defend the central nervous system against acute or chronic neuronal injuries. Even with the progress made over the last decades, most of the medications prescribed for the management of neurodegenerative diseases can only reduce their symptoms and slow down their progression. Based on natural product research, there are potential effective medicinal plants and phytochemicals for modulating neuronal functions and protecting against neurodegeneration. Plants in the genus Pistacia are also among valuable natural resources for neuroprotection research based on experiences in traditional medicine. Studies have supported the value of bioactive compounds of the genus Pistacia for central nervous system disorders such as Alzheimerʼs, Parkinsonʼs, multiple sclerosis, cerebral ischemia, depression, and anxiety. Related literature has also revealed that most of the evidence on neuroprotection in the genus Pistacia is in the form of preliminary studies, mainly including models of behavior, motor function, and memory impairments in animals, neural toxicity, cerebral ischemia and seizure models, evaluation of their effects on antioxidant and inflammatory biomarkers, amyloid β aggregation, and acetylcholinesterase as well as investigations into some cellular pathways. Along with the phytonutrients in kernels such as pistachios, various phytochemicals, mostly terpenes, and phenolic compounds have also been identified in different plant parts, in particular their oleoresins, of species in the genus Pistacia. In this review, the pharmacology of neurological effects and related molecular mechanisms of the plants belonging to the genus Pistacia and its active constituents, as well as pharmacokinetics aspects, are discussed.
