Background: Melatonin is involved in regulation of circadian rhythm and alleviation of sleep disorders, such as insomniadue to jet lag and shift work, as it plays a major role in synchronization of the sleep/wake cycleMaterials and methods: This study is devoted to extraction and determination of melatonin in Pistacia atlantica using anultrasound-assisted solid-liquid extraction (SLE) combined with UV-Vis Spectroscopy. The volume and type of extractionsolvent, sonication time, and extraction temperature on the extraction efficiency were optimized.Results: Under optimum conditions, use of 30 mL of ethanol and 30 min sonication time caused to achieve the limit ofdetection (LOD) of 0.047 ppm. The method accuracy was confirmed according to the calculation of recovery using standardaddition method that, exhibited the successful applicability of the present method for real sample analysis. In addition, theobtained results were compared to those using gas chromatography/Mass spectroscopy (GC/MS). Combination of SLE andUV-Vis leads to greater sensitivity and lower cost for accurate and repeatable extraction of melatonin from Pistacia atlanticawith acceptable recovery and RSD% (1.04%).Conclusion: Therefore, we efficiently extracted and purified of melatonin from an inexpensive source (Pistacia atlanticafruit). The extracted melatonin can be replaced synthetic drugs.

Background: Oxidative stress and free radicals play a crucial role in muscle fatigue. Pistacia vera (P. vera) contains manyantioxidant substances such as coenzyme Q-10, vitamin E and beta-carotene. The current study has been designed to evaluatethe effects of P. vera seeds (pistachios) on skeletal muscle fatigue in male Wistar rats.Materials and methods: 50 Male Wistar rats were randomly divided into five groups, including the normal, vehicle andtreated groups of pistachio extracts (10, 100, and 1000 mg/kg). Muscle fatigue was induced by treadmills. Animals would runat the speed of 20 m/min on a treadmill until they showed fatigue signs. This protocol was repeated for 10 days. The hydroalcoholic extracts of pistachios were gavaged 30 minutes before the induction of muscle fatigue every day. On the 11th day, ratswere sacrificed and biochemical parameters such as creatine phospho-kinase (CPK), lactate dehydrogenase (LDH) and aspartateaminotransferase (AST) levels were measured in the plasma.Results: The different doses of the pistachio extract led to an increase in the fatigue time on days 2 (100 mg/kg) (p<0.05), 4(10 and 100 mg/kg) (all p<0.05), 5 (10 and 1000 mg/kg) (all p<0.05), 7 (10 and 1000 mg/kg) (all p<0.05) and 9 (100 mg/kg)(p<0.05). The induction of muscle fatigue led to an increase in the serum activity of CPK, LDH and AST (all p<0.01). Thepistachio extract (10 and 100 mg/kg) decreased the serum activities of LDH and AST (all p<0.05).Conclusion: According to the results of this study, it was concluded that pistachios could decrease skeletal muscle fatigue in male Wistar rats.

Background: The cracking of pistachio nuts is the major source of mold contamination as well as pests and aflatoxins.Materials and methods: The effects of deficit irrigation on pistachio-nut cracking were evaluated at two irrigation intervals(25 days and 45 days) and five omissions of the irrigation time. The frequencies of hull early splitting and cracking weredetermined in nuts.Results: All and all, long irrigation intervals and deficit irrigation since late April until early June were critical andincreased the early splitting rate (up to 90%) in comparison with regular irrigation. The highest frequencies of the earlysplitting of pistachios were observed due to the drought stress at early June ranging from 7.7 percent to 9.6 percent. Deficitirrigation in July increased the rate of pistachio hull cracking significantly. The averages of the hull early splitting andcracking formation were by 37 percent and 18.5 percent higher in 45 days of irrigation intervals compared with 25 days,respectively. The contents of B1 and B2 aflatoxins in hull early splitting and cracking were 223.4 µg.kg-1 and 25.47 µg.kg-1,respectively. In hull cracking fruits, aflatoxin B1 and B2 were 111.06 µg.kg-1 and 9.71 µg.kg-1, respectively.Conclusion: In general, to reduce the risks of aflatoxins in pistachio nuts, it is critical to manage irrigation in April andJune.

Aflatoxins (AFs) are fungal subsidiary products that are predominantly generated by Aspergillus flavus and Aspergillusparasiticus strains on cereals, nuts, dried fruits and dairy products under warm and humid conditions. Harmful fungi causespoilage in agricultural crops, and mycotoxins exert harmful effects on humans and livestock. Pistachios (Pistachio vera L) arefrom among the most well-known nut trees extremely susceptible to contamination by aflatoxins and the major contributors todietary aflatoxins. Aflatoxins, in particular aflatoxin B1 (AFB1), are from among the most toxic natural compounds withcarcinogenic effects. Besides, exposure to aflatoxins results in several health-related conditions in humans, including acute andchronic aflatoxicosis, immune suppression, liver cancer/cirrhosis, and stunting. Some traditional and novel control strategieshave been proposed for the elimination of AF prevalent in food crops. The application of nanoparticles is a newly advancedmethod where they are used as antibacterial, antifungal, antiviral, anti-inflammatory, and anticancer agents. Nanoparticles aremost widely used for the molecular detection of pathogens at the early stages of the plant growth and for the control ofdiseases. In this paper, the utilization and effects of nanomaterials on controlling aflatoxigenic fungi and their toxicity onpistachio nuts have been studied.

Background: Aspergillus parasiticus is one of the primary sources of aflatoxin contamination in agricultural crops,especially nuts. Aflatoxin contamination is one of the most challenging problems in the production and exportation ofpistachios.Materials and Methods: In this study, the antifungal effects of the silver-zinc mixture and silver nanoparticles on themycelia growth, spore germination and aflatoxin production of Aspergillus parasiticus have been evaluated.Results: The findings of the current study showed that the concentrations of 1250 ppm of Ag/Zn and 100-200 ppm of Agnanoparticles inhibit mycelia growth and the spore germination of Aspergillus parasiticus in liquid and solid mediasignificantly, but the concentration of 25 ppm of both nanoparticles has no inhibitory effects on the A. pararsiticus growthparameter. The results showed that the rate of inhibitory effects depends on the type of the medium and nanoparticles, but thefungal isolate had no significant effects on nanoparticles’ inhibitory features.Conclusions: Ag/Zn nanoparticles had no regular effect on the reduction of aflatoxin production, yet Ag nanoparticlesreduced the production of aflatoxins, especially aflatoxins B2 and G2.
