The current study aimed to determine the activities of the phytochemical constituent (i.e., phenolic and flavonoid total contents) with various concentrations of ethanolic extract of M. calabura leaves (EEMC) to determine the best one and the in vitro antioxidant activities and quercetin content using TLC Densitometry. The extraction was carried out by maceration with various concentrations of ethanol (96% v/v; 70% v/v and 50% v/v) to obtain the ethanolic extract of Muntingia calabura , L leaves. The determination of Quercetin was conducted by Thin Layer Chromatography (TLC) densitometry, and the total phenolic was analyzed with reagent Folin-Ciocalteu while the flavonoid content we identified by applying the colourimetric method. The antioxidant capacity was measured using the radical scavenging assay of 1,2-diphenyl-2-picrylhydrazyl (DPPH). The phytochemical study showed that phenolics, saponins, tannins, and flavonoids were present in all EEMC. The extract obtained by 96% ethanol showed the highest total antioxidant activity, reducing power and DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging activity. The same extract also exhibited the highest flavonoid content. However, the extract obtained by 70% ethanol showed the phenolic content, and the highest quercetin content was obtained by using 50% ethanol. The result from the EEMC analysis indicated that Muntingia calabura leaf extract contains essential bioactive compounds and shows potential as a source of antioxidants in M calabura which uses 96% ethanol solvent and has the highest quercetin content in M calabura using 50% ethanol solvent Keywords: DPPH, Muntingia calabura , phenolic total, antiradical activity, TLC densitometry","PeriodicalId":314392,"journal":{"name":"Journal of Food and Pharmaceutical Sciences","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126548522","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several parts of plants such as bark, root, leaf, stem, etc. are being used torevert abnormalities back to normal, prevent illnesses, or allay symptoms.

Alkaloids have a rangeof pharmacological activities such as antiasthma (e.g. ephedrine), anticancer (e.g. homoharringtonine),antimalarial (e.g. quinine). Other alkaloids possess stimulant (e.g. cocaine, caffeine, theobromine, nicotine)and psychotropic activities (e.g. psilocin), and have been widely used as recreational drugs orin entheogenic rituals. Alkaloids can be toxic too (e.g. tubocurarine, atropine). Although alkaloids act ondiverse metabolic systems in humans and animals, they almost uniformly induce a bitter taste. Thecharacteristics and number of the structures of phenol in polyphenols underlie the unique chemical,physical, and biological (metabolic, therapeutic, toxic, etc.) properties of specific members of the class;e.g. ellagitannin and tannic acid. Generally, foods often contain complex mixtures of polyphenols. Severalpolyphenolic extracts, such as from grape seeds, olive pulp, maritime pine bark, or grape skin, are sold asingredients for functional foods, cosmetics, and dietary supplements. Terpenoids and terpenes are theprimary components of the essential oils of most types of flowers plants. Essential oils are used widely asscents and fragrances in perfumery and also in traditional medicine, such as aromatherapy. Similarly,many plant glycosides are used as medicines.

The possible antioxidant effect of taurine was also studied by measuring its protective effect against cyclophosphamide induced lung injuiry. Taurine produced a concentration dependent relaxation in the isolated tracheal strips and pulmonary arterial rings precontracted by serotonin (2x10-4 mM). The relaxing effect of taurine was not influenced by pretreatment with nitric oxide synthase inhibitor (L-NAME) , cysteinyl leukotreines receptor 1 blocker (montelukast) , H1 receptor blocker (chlorpheniramine) , β-adrenoceptor blocker (propranolol), potassium channel blocker (amiodarone) , cyclo-oxygenase inhibitor (indomethacin) or muscarinic receptor blocker (atropine). Preincubation with adenosine receptor blocker (aminophylline) significantly potentiated the relaxing effect of taurine in the tracheal strips and pulmonary arterial rings. Cyclophosphamide (CYP, 150 mg/kg) administerated i.p. in a single dose was used to produce lung injuiry in rats. CYP caused marked increase in lung lipid peroxides (MDA) and decrease in lung reduced glutathione (GSH). Administration of taurine (1% in drinking water) starting 7 days before CYP and continuing throughout the duration of the experiment (24 hours) improved significantly the lung GSH and MDA.
