  This review aims to evaluate the intrinsic properties and different applications of phycocyanin pigment in the food and pharmaceutical industries. In addition, in each section, a detailed history of the research conducted in the field of phycocyanin is presented. Phycocyanin is a blue pigment, a light receiver with antioxidant and fluorescent properties in cyanobacteria, and two algae from the genus rhodophytes and cryptophytes. Phycocyanin pigment consists of two relatively similar subunits α and β. The alpha chain contains one phycocyanobilin attached to cysteine 89 and the beta chain contains two phycocyanobilins attached to cysteines 84 and 155. Phycocyanin is commercially produced from spirulina algae (spirulina platensis), in the form of photoautotrophic cultures, and open environments in large ponds or pools in tropical or subtropical areas at the edges of oceans. This pigment can be extracted from the mentioned algae by using different techniques such as enzymatic method, ultrasound, freezing-defrosting, mineral solvent, homogenization, stress and osmotic shock, high hydrostatic pressure, ultracentrifuge, and ultra homogenization. Depending on the extraction conditions, each method has its advantages and disadvantages, but the enzymatic and ultrasound methods are more efficient than other methods. Phycocyanin has many medicinal and therapeutic properties, including anti-cancer and anti-inflammatory; In addition, the positive effect of this pigment on nerve cells, kidneys, and the immune system has been confirmed. Phycocyanin, having three colorings, antioxidant and antimicrobial properties, has the potential to be used in various food formulations, such as yogurt, cheese, ice cream, etc., which have been proven in various research.

  Citrus aurantium L. seed is a by-product of fruit juice industries. In this research, the main fatty acids and phytosterols in C. aurantium seed oil were evaluated with the aim of nutritional evaluation and its biological properties. The C. aurantium oil extracted by two methods of cold pressing and using hexane solvent.The C. aurantium seed fatty acids composition was analyzed by GC-MS, 1HNMR, and 13CNMR. In addition, the effects of ultrasonic waves and air pressure on the C. aurantium pulp obtained from cold press extraction by n-hexane was studied. The findings showed that the highest oil yields were obtained using ultrasound-assisted extraction (25%) compared to other methods. The five fatty acids including 9-oleic (18.07%), Linoleic (36.69%), palmitic (21.90%), stearic acid (6.6%) and 10-oleic acids (1.1%) were the most phytosterols in C. aurantium seed oil. According to the obtained results, C. aurantium oil can be considered as a new food source. Manuscript profile

  Neem (Azadirachta indica) that belongs to the Meliaceae family has many medicinal properties such as treatment of skin diseases, hypoglycemia, hypertension, cancer, and AIDS. In this study, to investigate the effect of different solvents on the quantity and quality of phytochemical properties of neem collected from Bahoklat area in Chabahar city, a factorial experiment was conducted in a completely randomized design in 2021. Ethanol, methanolic, n-hexane and acetone extracts of neem leaves and fruits were prepared by cold maceration method. Total phenol content, total flavonoid and antioxidant activity were measured by folin-cicalto reagent, aluminum chloride colorimetric and diphenylpicrylhydrazyl free radical scaving (DPPH) methods, respectively. The results showed that the effect of organ type, solvent type and their interaction on all measured traits was significant. Based on the results, the highest amount of total phenol (48.22 mg Gallic acid / g dry weight) was reported in acetone leaf extract, and the lowest amount (2.76 mg Gallic acid / g dry weight) was reported in hexane extract of fruit. In addition, the highest amount of total flavonoids was observed in acetoin fruit and leaf extracts (4.71 and 4.61 mg Quercetin / g dry weight, respectively) and the lowest amount (3.22 mg quercetin / g dry weight) was obtained in the hexane extract of fruit. The highest and the lowest antioxidant activity was detected in ethanolic leaf extract (94.77%) and acetone extract of fruit (12.02%), respectively. Therefore, neem leaf is suggested as a useful source of phenolic compounds and natural antioxidants. Manuscript profile
