In this in vivo study, by evaluating a set of physiological parameters and biochemical markers, we investigated the effectiveness of the developed FFIs from Chenopodium quinoa grains in stress conditions induced by daily episodes of immobilization for 36 days. The results of the evaluation of the anxiety-like functions, locomotor, and search activity of rats in the \u201copen field\u201d and \u201celevated plus maze\u201d tests demonstrated the ability of FFIs to reduce stressful behavior induced by immobilization. The improvement in the long-term memory of animals treated with FFIs was noted in the passive avoidance test. Together with the hypolipidemic effect and compensation of transaminase levels, FFIs normalized the excretion of catecholamines in the urine and reduced the levels of malondialdehyde to values of the control group. According to the results of the assessment of FFI acute oral toxicity, the LD50 value exceeded 5000 mg\/kg of body weight, which categorizes the FFIs under hazard class 5\u2014substances with low hazard. The conducted experiment demonstrated the effectiveness of nutritional support with FFIs on the selected stress model. The positive safety profile of FFIs makes them reasonable to study on other stress models and to conduct clinical testing as part of specialized food products in various categories of people exposed to chronic stress.<\/jats:p>","DOI":"10.3390\/molecules27249003","type":"journal-article","created":{"date-parts":[[2022,12,19]],"date-time":"2022-12-19T09:05:09Z","timestamp":1671440709000},"page":"9003","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Anxiolytic and Antioxidant Effect of Phytoecdysteroids and Polyphenols from Chenopodium quinoa on an In Vivo Restraint Stress Model"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2168-2659","authenticated-orcid":false,"given":"Yuliya S.","family":"Sidorova","sequence":"first","affiliation":[{"name":"Federal Research Centre of Nutrition and Biotechnology, 109240 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0015-8735","authenticated-orcid":false,"given":"Vladimir A.","family":"Shipelin","sequence":"additional","affiliation":[{"name":"Federal Research Centre of Nutrition and Biotechnology, 109240 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9755-6002","authenticated-orcid":false,"given":"Nikita A.","family":"Petrov","sequence":"additional","affiliation":[{"name":"Federal Research Centre of Nutrition and Biotechnology, 109240 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergey N.","family":"Zorin","sequence":"additional","affiliation":[{"name":"Federal Research Centre of Nutrition and Biotechnology, 109240 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir K.","family":"Mazo","sequence":"additional","affiliation":[{"name":"Federal Research Centre of Nutrition and Biotechnology, 109240 Moscow, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,12,17]]},"reference":[{"key":"ref_1","first-page":"114","article-title":"Nutrients and Botanicals for Treatment of Stress: Adrenal Fatigue, Neurotransmitter Imbalance, Anxiety, and Restless Sleep","volume":"14","author":"Head","year":"2009","journal-title":"Altern.
