i n a l aticp d ic la e nts medicinal aromatic plants,in ethiopia, r. officinalis is locally known as yetibs qitel used for flavor of various cuisine. three varieties of r. officinalis were registered at wendo genet agricultural research center and aimed to define the physico-chemical properties and antioxidant activities of their essential oils.
the in vitro antioxidant activities of extracts from 54 plant species from 33 plant families were identified .table 1 provides a summary of the plant species that were tested, their family, the portions of the plants that were utilized to generate the test samples, the solvent used during the extraction process, the assay methods, and their
ethnomedicine, antibacterial activity, antioxidant potential
ethanolic extracts of gnidia involucrata steud. ex a.rich. stems and roots were effective antioxidants, with respective 50% dpph free radical inhibitory concentrations (ic 50) of 168.68 and 181.79 µg/ml, followed by that of p. steudneri (ic 50 = 203.11 µg/ml).
in vitro antioxidant activity and polyphenolic content of,introduction: in this study, the antioxidative effectiveness, and polyphenolic content of methanol and aqueous extracts of spices such as lippia adoensis (koseret), nigella sativa (thikur azmud), piper capense (timiz), thymus schimperi (tosign) and trachyspermum ammi (netchazmud), consumed among people of ethiopia were investigated.
ascorbic acid content and the antioxidant activity of common
the present work was aimed to determine the contents of ascorbic acid and the antioxidant activity of eight types of common fruits commercially available in addis ababa, ethiopia using...
novel antioxidants based on polymerized 2,2,4-trimethyl-1,2,poly(2,2,4-trimethyl-1,2-dihydroquinoline) [tmq] was used as a commercial antioxidant. carbon black (high abrasion furnace; haf) was used as reinforcement agent. processing oil was used as a plasticizer.
phytochemical profile and antioxidant capacity of some wild
in vitro, antioxidant activities were evaluated using 2,2-diphenyl-1-picrylhydrazyl (dpph) and ferric reducing antioxidant power (frap) tests. β-carotene and vitamin c content were assessed using spectrophotometric and titration, respectively.
in vitro antioxidant activity and polyphenolic content of,in this study, the antioxidative effectiveness, and polyphenolic content of methanol and aqueous extracts of spices such as lippia adoensis (koseret), nigella sativa (thikur azmud), piper capense (timiz), thymus schimperi (tosign) and trachyspermum ammi (netchazmud), consumed among people of ethiopia were investigated.
investigation of total polyphenol, antioxidant activity for sale
total polyphenol, antioxidant activity, and heavy metal contents in selected ethiopian beers (dashen= b1, harar = b2, habesha= b3, saint george= b4, and walya= b5) were investigated. the average concentration of total phenolic content in b1, b2, b3, b4, and b5 were found to be 219.80, 206.09, 190.24, 193.00, and 212.10 mg gae/l, respectively.
comparative study on chemical composition and antioxidant,ziziphus spina-christi (locally known as kunkura/gava) was collected from north wollo, ethiopia, in november 2018 whereas the three ziziphus jujube fruit species (locally known as umaran, gola, and mundia) were collected from haryana, india, in january 2018 in the morning sessions.
- Is TMQ a good antioxidant?
- TMQ (2,2,4-trimethyl-1,2-H-dihydroquinoline) is an important antioxidant because of relatively low price and ease of application in rubber production technologies. However, due to the limited experimental data and unclear reaction mechanism, the quality of the TMQ product needs to be improved in industry processes.
- What are TMQ polymers?
- TMQ is chemically modified to obtain new derivatives, namely; Ester, Hydarzide, Oxadiazole and Triazole. The synthesized polymers are characterized by Fourier transforms infrared spectroscopy (FTIR) and proton-nuclear magnetic resonance (1 HNMR). The formed polymers are evaluated as antioxidants for styrene-butadiene rubber (SBR) composites.
- How is TMQ synthesized?
- Novel antioxidants based on polymerized 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ) are synthesized. TMQ is chemically modified to obtain new derivatives, namely; Ester, Hydarzide, Oxadiazole and Triazole. The synthesized polymers are characterized by Fourier transforms infrared spectroscopy (FTIR) and proton-nuclear magnetic resonance (1 HNMR).
- What is TMQ used for?
- Poly (2,2,4-trimethyl-1,2-dihydroquinoline) [TMQ] was used as a commercial antioxidant. Carbon black (high abrasion furnace; HAF) was used as reinforcement agent. Processing oil was used as a plasticizer. N -cyclohexyl-2-benzothiazole sulphenamide (CBS) was used as an accelerator.
