The stem bark of Enantia chlorantha is commonly used for the treatment of malaria and other ailments of the human body such as cough and wound. The plant had been intensely studied for its antimicrobial activities and antipyretic properties. However, the efficacy and mechanisms of action of the plant remain unclear. Therefore, the objective of the present study was to determine the in vitro ant...

A method for the spectrophotometric determination of nitric oxide, nitrite, and nitrate in tissue culture media is presented. The method is based on the nitric oxide-mediated nitrosative modification of sulfanilic acid that reacts with N-(1-naphthyl)ethylenediamine dihydrochloride forming an orange-colored product absorbing at 496 nm. Nitric oxide levels were determined in culture media from th...

INTRODUCTION Intracellular and extracellular oxidative stress triggered by free radicals promotes skin aging, which is designated by atypical pigmentation and wrinkles. The consumption of antioxidants is an efficacious measure to avert symptoms involved in skin aging. AIM The current research was commenced to explore the anti-aging potential of antioxidants present in Tamarindus indica seeds ...

Antioxidants play an important role in protecting the cell from damage caused by oxidative stress (OS). Plants have potential phytochemicals, which possess antioxidant properties. The present study was designed to investigate screening of phytochemcials, antioxidant, and antidiabetic properties ethanolic leaf extracts Psidium guajava varieties (Lucknow 49 TRY G1). were screened for various phyt...

The water and MeOH extracts of the stems of Quercus coccifera L. are screened for their radical scavenging activity against 2,2-diphenyl-1-picryl hydrazyl (DPPH), superoxide (SO) and nitric oxide (NO) radicals spectroscopically. Dose dependent radical scavenging activity was observed and the results were found to be comparable to that of known antioxidant compounds BHA (3-t-butyl-4-hydroxyaniso...

BACKGROUND Production of reactive oxygen species is a common cause in alcohol induced liver diseases. Decoction prepared from the whole plant of Eriocaulon quinquingulare is prescribed to treat liver disorders. The aim of this study was to investigate the hepatoprotective activity and antioxidant capacity of the water extract of E. quinquangulare in vitro. METHOD The aqueous extract of the wh...

Dextrans (α-d-glucans) extracted from Leuconostoc mesenteroides, with molecular weights (MW) of 10 (D10), 40 (D40) and 147 (D147) kDa, were evaluated as antioxidant, anticoagulant and immunomodulatory drugs for the first time. None presented anticoagulant activity. As for the antioxidant and immunomodulatory tests, a specific test showed an increase in the dextran activity that was proportional...

'Mato Peiyu' pomelo (Citrus grandis (L.) Osbeck 'Mato Peiyu') leaves from pruning are currently an agricultural waste. The aim of this study was to isolate essential oils from these leaves through steam distillation (SD) and solvent-free microwave extraction (SFME) and to evaluate their applicability to skin care by analyzing their antimicrobial, antioxidant (diphenyl-1-picrylhydrazyl scavengin...

Extracts obtained from the leaves of various Alocasia species have been used in India as folk remedy for the treatment of various inflammatory ailments including rheumatism and bruise. The ethanolic extract of leaves of Alocasia indica Schott. was evaluated by using different in vitro antioxidant models of screening like scavenging of 1, 1-diphenyl-2-picryl hydrazyl (DPPH) radical, nitric oxide...

BACKGROUND Oxidative stress predisposes the human and animal body to diseases like cancer, diabetes, arthritis, rheumatoid arthritis, atherosclerosis and chronic inflammatory disorders. Hence, this study seeks to determine the antioxidant, anti-inflammatory and anti-arthritic activities of acetone leaf extracts of nine South African medicinal plants that have been used traditionally to treat ar...
