Phenolic components, antioxidant activity, and mineral analysis of Capparis spinosa L

In addition to being consumed as food, caper (Capparis spinosa L.) fruits are also used in folk medicine to treat inflammatory disorders, such as rheumatism. C. spinosa L. is rich in phenolic compounds, making it increasingly popular because of its components’ potential benefits to human health. We analyzed a number of individual phenolic compounds and investigated in vitro biological activities of C. spinosa L. Sixteen phenolic constituents were identified using reverse phase-high performance liquid chromatography (RP-HPLC). Total phenolic compounds (TPCs), ferric reducing antioxidant power (FRAP) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging activity were used as determinants of antioxidant capacity. C. spinosa L. exhibited strong antioxidant activity and contained high levels of antioxidant compounds. Gentisic, sinapic and benzoic acid were detected in C. spinosa L. No gallic acid, proto-catechuic acid, proto-catechuic aldehyde, chlorogenic acid, p-OH benzoic acid, vanillic acid, caffeic acid, syringic acid, vanillin, syringaldehyde, p-coumaric acid, ferulic acid or rosmarinic acid were identified. Iron and zinc were present at high levels in samples. C. spinosa L. appears to be a good source of antioxidants and minerals that might serve to protect health and combat several diseases.Key words: Antioxidant, capers, Capparis spinosa L., phenolics

EVALUATION OF THE SLIMMING EFFECTS OF DIET TEA IN BIOCHEMICAL AND MOLECULAR MEANING

The replacement of consumed with foods containing high carbohydrates, fats and proteins exceed that the daily needs of body, causes many health problems, especially obesity. Complicated health problems have been trying to be solved with drugs, but it is not possible to control diseases if obesity is not resolved. Obesity causes inflammation, insulin resistance, vascular endothelial dysfunction, and Low-Density Lipoprotein (LDL) increase. There are very few weight loss drugs with acceptable side effects, and these drugs are not given to people who are not considered obese according to their body mass index. For this reason, people seek the remedy in over the counter (OTC) (mostly products with active ingredients derived from plants) products or herbal teas. These products, which do not have direct effects, have mechanisms that can help and can be supportive with diet and sports. However, these products and teas that cannot be dosed by a knowledgeable healthcare professional can disrupt the balance of the body and cause various diseases. In this study, the effect levels with the mechanisms supporting weight loss on the biochemical parameters of the active substances in the herbal forms sold and consumed as diet tea, were evaluated.                   Peer Review History: Received: 4 July 2021; Revised: 11 August; Accepted: 6 September, Available online: 15 September 2021 Academic Editor:  Dr. Jennifer Audu-Peter, University of Jos, Nigeria, [email protected] UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.  Received file:                Reviewer's Comments: Average Peer review marks at initial stage: 6.0/10 Average Peer review marks at publication stage: 7.5/10 Reviewers: Dr. Gehan Fawzy Abdel Raoof Kandeel, Pharmacognosy Department, National Research Centre, Dokki, 12622,  Giza, Egypt, [email protected]  Dr. Marwa A.

BIOLOGICAL ACTIVITY AND CHARACTERIZATION OF VOLATILE COMPOUNDS OF TEUCRIUM ORIENTALE VAR. GLABRESCENS BY SPME AND GC-FID/MS

EYUPOGLU, Ozan Emre/0000-0002-4449-0537; Alpay Karaoglu, Sengul/0000-0003-1047-8350WOS: 000397284000031This study describes the constituents of phenolic acids, volatile components, antioxidant and antimicrobial activities of Teucrium orientale var. glabrescens. Antioxidant activity of methanolic and aquous extracts were examined by three different methods, namely ferric reducing antioxidant power, cupric reducing antioxidant capacity and 2,2-diphenylpicrylhydrazyl radical scavenging activity. the phenolic constituents were also determined by reverse phase-high performance liquid chromatography. Solid phase microextraction of Teucrium orientale var. glabrescens was analyzed by Gas Chromatography-Flame Ionization Dedector/Mass Spectromerty, Solid-Phase Microextraction (GC-FID/MS, SPME). the antimicrobial activity was studied by agar diffusion method. Extracts showed strong antioxidant and antimicrobial activity and contained large amounts of antioxidant compounds. Rosmarinic acid, p-coumaric acid and p-hydroxybenzoic acid were detected in methanolic extract of plant. Aquous extract was especially effective against Mycobacterium smegmatis. the main chemical classes identified consisted of aldehydes (32.5%), hydrocarbons (29.8%) and monoterpene hydrocarbons (29.8%). Common volatile components of plant detected included nonanal, thuja-2,4 (10)-diene and tetracosane
