Butanol fraction was evaluated for antidepressant-like effect in the tail suspension, forced swimming and open field tests. All animals were treated with BF (5, 10 &amp; 20\u2009mg\/kg) thirty minutes prior to the tests. On the other hand, monoaminergic neurotransmission involvement was probed by pre-treating animals with yohimbine hydrochloride (1\u2009mg\/kg, \u03b12 antagonist), prazosin (62.5\u2009\u00b5g\/kg, \u03b11 antagonist), propranolol (2\u2009mg\/kg, non-selective \u03b2 antagonist), sulpiride (50\u2009mg\/kg, D2 receptor blocker), haloperidol (0.2\u2009mg\/kg, non-selective D receptor blocker), metergoline (4\u2009mg\/kg, i.p., a 5HT-receptor blocker) and PCPA (100\u2009mg\/kg, i.p., inhibitor of tryptophan hydroxylase), fifteen minute before treatment with BF (10\u2009mg\/kg). Identification of the major bioactive constituents was done by HPLC. The findings show that BF (5 &amp; 10\u2009mg\/kg) significantly decreased immobility in despair tests of depression without effect on locomotor activity. The data also shows that anti-immobility effect of BF (10\u2009mg\/kg) in the TST was reversed by prazosin, yohimbine, haloperidol, sulpiride, metagoline and PCPA but not with propranolol. Bioactive principles present are caffeic acid, rutin, morin and quercetin. In conclusion, our findings show that BF produces antidepressant-like effect, which may be dependent on its interaction with the monoaminergic system.<\/jats:p>","DOI":"10.1055\/a-0651-7939","type":"journal-article","created":{"date-parts":[[2018,8,2]],"date-time":"2018-08-02T23:10:13Z","timestamp":1533251413000},"page":"53-60","source":"Crossref","is-referenced-by-count":14,"title":["Butanol Fraction of Olax Subscorpioidea Produces Antidepressant Effect: Evidence for the Involvement of Monoaminergic Neurotransmission"],"prefix":"10.1055","volume":"69","author":[{"given":"Adebayo","family":"Adeoluwa","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Therapeutics, Faculty of Basic Clinical Sciences, College of Medicine and Health Sciences, Afe Babalola University Ado Ekiti, Ekiti State, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Oladele","family":"Aderibigbe","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Therapeutics, Faculty of Basic Medical Sciences, College of Medicine, University of Ibadan, Ibadan, Oyo State Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Isaiah","family":"Agboola","sequence":"additional","affiliation":[{"name":"Department of Pharmacognosy and Herbal Medicine, Faculty of Pharmacy, Niger Delta University, Wilberforce Island Bayelsa State, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toyin","family":"Olonode","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Therapeutics, Faculty of Basic Clinical Sciences, College of Medicine and Health Sciences, Afe Babalola University Ado Ekiti, Ekiti State, Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Benneth","family":"Ben-Azu","sequence":"additional","affiliation":[{"name":"Department of Pharmacology and Therapeutics, Faculty of Basic Medical Sciences, College of Medicine, University of Ibadan, Ibadan, Oyo State Nigeria"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"194","published-online":{"date-parts":[[2018,8,2]]},"container-title":["Drug Research"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/www.thieme-connect.de\/products\/ejournals\/pdf\/10.1055\/a-0651-7939.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2018,12,21]],"date-time":"2018-12-21T23:41:52Z","timestamp":1545435712000},"score":1,"resource":{"primary":{"URL":"http:\/\/www.thieme-connect.de\/DOI\/DOI?10.1055\/a-0651-7939"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2018,8,2]]},"references-count":0,"journal-issue":{"issue":"01","published-online":{"date-parts":[[2018,12,21]]},"published-print":{"date-parts":[[2019,1]]}},"URL":"https:\/\/doi.org\/10.1055\/a-0651-7939","relation":{},"ISSN":["2194-9379","2194-9387"],"issn-type":[{"value":"2194-9379","type":"print"},{"value":"2194-9387","type":"electronic"}],"subject":[],"published":{"date-parts":[[2018,8,2]]}}}
