The effect of pomegranate seed oil on human health, especially epidemiology of polycystic ovary syndrome; a systematic review

Abstract

Polycystic ovary syndrome is the most common endocrine disorder in women. Today, medicinal plants have been considered by women, especially in the reproductive and pregnancy ages. Multiple drug treatments and the length of the treatment period often lead to incomplete treatment by patients. Therefore, due to the side effects of chemical drugs, this study was conducted to assess investigate the effect of pomegranate seed oil on polycystic ovary syndrome. The prevalence of polycystic ovary syndrome is increasing by 15 to 20% and clinically includes oligomenorrhea or amenorrhea, hirsutism, and often infertility. Databases such as Cochran library, Medline, PubMed, SID, and Science Direct were used to access the related articles. To collect the required information, first, the articles that had one of the keywords of medicinal plants, polycystic ovary syndrome, plant, pomegranate extract, and menstrual irregularities in their text were searched in databases. All studies from 1985 to 2021 are included in the study. Conjugated linolenic acid (CLN) is a group of geometric and positional isomers of linolenic acid in which double bonds are conjugated. CLN has been reported to have a very strong cytotoxic effect on tissue tumor cells in the body, preventing cancer, reducing the accumulation of triacylglycerol in the liver, polycystic ovary syndrome, and LDL cholesterol in the blood. So far, seven CLN isomers have been identified, including ponic acid in pomegranate seed oil. Conjugated linoleic acid (CLA) is a group of situational and geometric isomers of linoleic acid in which double bonds are conjugated. The positive effects of the two main CLA isomers (cis-9, trans-11, and trans-10, cis-12) include inhibiting the growth of cancer, reducing the risk of atherosclerosis, and reducing body fat.

Evaluation of physicochemical, antioxidant, antibacterial activity, and sensory properties of watermelon rind candy

“…Moreover, watermelon is a considerable source of vitamins such as A, B vitamins (mainly B1 and B6), and minerals including K and Mg [ 6 ]. The therapeutic and pharmacological values of watermelon have been informed, which is associated with antioxidant components such as carotenoids and lycopene [ [7] , [8] , [9] , [10] ]. Lycopene has been revealed to have a protective role against numerous types of cancer [ 11 , 12 ], as well it aids suppressing the inflammations that leads to different diseases including atherosclerosis, asthma, diabetes, arthritis, and cancers, especially, prostate cancer [ 13 ].…”

Measurement of Phenolic Compounds by Spectrometry and Chromatography in Lime Juices

“…Flavonoids are polyphenolic substances isolated from a wide range of plants with many health-related properties due to their high antioxidant capacity [1,2]. ey exhibit various physiological properties such as anti-in ammatory, antiallergic, anticarcinogenic, antihypertensive, and antiarthritic activities [3][4][5][6][7].…”

Influence of green pepper extract on the physicochemical, antioxidant, and sensory properties of stirred yogurt

“…Phenolic compounds, oligosaccharides, and probiotics are constituents of this particular food variety, yet they remain relatively unfamiliar to consumers. Phenolic phytochemicals, which are secondary metabolites derived from plants, make up a significant portion of the diets of both humans and animals ( Bahmani et al, 2022 , Falahi et al, 2019 , Lin et al, 2016 , Sadighara et al, 2016 , Shavali-Gilani et al, 2023 ). Oxidative stress and systemic inflammation are the key pathogenic factors that contribute to the progression of metabolic disorder, insulin resistance, β-cell dysfunction, and ultimately diabetes.…”
