BACKGROUND Diabetes mellitus is one of the most common endocrinal disorders and medicinal plants continue to play an important role in the management of this disease. In this study, Rosa canina was investigated for the antioxidant and α-amylase inhibition activities. MATERIALS AND METHODS Methanolic extract of Rosa canina was investigated for its potential antioxidant activity. The extracts' ...

The presence of phenolic, flavanoid and tannin compound content in the methanolic extract of Garcinia atroviridis were investigated in this study using UV-Vis Spectrometry and consequently find the relationship between the chemical contents with the antioxidant activity. Garcinia atroviridis has phenolic content the highest followed by flavonoid and tannin content. The antioxidant activities of...

Pomegranate (Punica granatum L.), Lythraceae, is mainly grown in Mediterranean region. It is one of the major cultivated productions of Iran, which have been used in folk medicine for many centuries. It has been proved that pomegranate has a high antioxidant activity and is effective in the prevention of atherosclerosis. This study compares the antioxidant activity, total phenolic and flavonoid...

Variations in total phenolic and flavonoid contents as well as antioxidant activity of Bellis perennis (common daisy) flowers were investigated. The flowers were collected monthly (from March to October, i.e., during the usual flowering season of the plant) at three localities in three different years. Total flavonoids were determined spectrophotometrically by two methods: by formation of a com...

BACKGROUND Scrophularia striata (Scrophulariaceae family) is an herbaceous plant that is traditionally used for treatment of microbial infections. OBJECTIVES Antimicrobial and antioxidant activity of different extracts (methanolic, ethanolic, aqueous and ethyl acetate) from S. striata aerial parts was evaluated. MATERIALS AND METHODS The antimicrobial activity of different extracts from S. ...

This study developed an efficient and reliable system for inducing polyploidy in Anoectochilus formosanus Hayata, a top-grade medicinal orchid. The resulting tetraploid gave a significant enhancement on various agronomic traits, including dry weight, fresh weight, shoot length, root length, leaf width, the size of stoma, and number of chloroplasts per stoma. A reduction of the ratio of length t...

Endogenous and exogenous antioxidants are used to neutralise free radicals and protect the body from free radicals by maintaining the redox balance. The antioxidant properties of Dracaena sanderiana leaves were evaluated using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, and the total phenolic and flavonoid contents were measured. The classes of secondary metabolites were evaluated through p...

Microctis Folium, the leaves of Microcos paniculata L., is a commonly used herbal tea material. The methanol extract of Microctis Folium and its principle compounds vitexin (1), isovitexin (2) and isorhamnetin 3-O-β-D-rutinoside (3) were investigated for their α-glucosidase inhibitory effects. The extract showed strong α-glucosidase inhibitory effect (IC₅₀ = 61.30 μg/mL) and the three flavonoid...

The migration of flavonoids from low-density polyethylene (LDPE) film (0.4%, w/w) to aqueous food simulants over 16 weeks at 0, 15, and 30 °C was investigated. The migration amount of total flavonoids was calculated based on the rutin contents determined by high-performance liquid chromatography (HPLC). Diffusion and partition coefficients, along with the activation energy (Ea) were calculated ...
