A Review of Extraction Methods for Obtaining Bioactive Compounds in Plant-Based Raw Materials
(2023) Verep, D.; Ateş, S.; Karaoğul, E.
In recent years, the usage of lignocellulosic biomasses in food supplements has become popular. The studies about the development of reliable and short-term methods in the extraction of these active components in lignocellulosic biomasses and the usage of eco-friendly solvents have increased gradually. Traditional extraction methods take a long time and use a large amounts of organic solvents. In addition, the damages of used organic solvents to the environment are high considerably. For this reason, the need for technologies that reduce the extraction time and reduce the use of organic solvents and environmentally friendly "green chemistry" solvents is increasing day by day. In this review, traditional and modern extraction methods were examined and general application areas of these methods were introduced. Traditional extraction methods include maceration, pressing, infusion, digestion, percolation, decoction, reflux, tincture, distillation, and soxhlet methods, and modern extraction methods including pressurized liquid extraction, supercritical fluid extraction, ultrasonic assisted extraction, microwave assisted extraction, pulsed electric field extraction, enzyme assisted extraction methods, and their variation parameters were investigated. It has been seen that modern extraction methods are performed in less amount of sample, lower volume of solvent, lower energy consumption, and shorter extraction times compared to traditional methods. Within the scope of the study, considering all these, it has been determined that modern extraction methods are more applicable to nature-friendly methods than traditional methods.
Is Somatization Escape From Stigmatization? A Cross-Sectional Study
(2024) Kaçan, H.; Ateş, S.; Üstün, B.
Somatization is a psychiatric condition characterized by repetitive bodily symptoms that cannot be fully explained by the medical condition of the individual and cannot be attributed to another mental disorder. This research aims to examine the relationship between the somatic symptoms of nursing students and their tendency to stigmatize. The research was conducted at two different universities and a total of 438 students participated. The data were collected using the personal information form, the "Somatization" subscale of the SCL-90-R scale, and the Stigma Tendency Scale. The average score of somatization of students was 0,98±0,70 and the average score of Stigma Tendency Scale was 45,39±11,69. It was found that female students, those who did not share their problems, those who had previously applied to a psychiatrist or psychologist and received mental therapy, those who took medication, those who recently felt the need for a psychiatrist or psychologist, students with a diagnosis of mental illness in their family and who knew about mental health and diseases had more somatic problems (p˂0,01). A weak negative statistically insignificant relationship was found between the general and subscale scores of somatization and Stigma Tendency Scale. The students who got high scores from the stigma tendency scale were found to get high scores from the somatization scale, although not statistically significant. Based on this result, it can be said that students with a high stigma tendency experience more somatic symptoms.
