This research paper presents findings of an investigation about antibacterial effect of methanol/water fractions as well as cytotoxic activity of the extracts obtained from Pedicularis wilhelmsiana (Scrophulariaceae) which grows in Azarbaijan/Iran by agar well diffusion method and brine shrimp lethality test successively. Phytochemical study of this plant was determined as well. A combination o...

Electrochemical oxidation of leaves extract of lemon verbena and the flowers extract of echium amoenum have been studied in the absence and presence of barbituric acid and 1,3 dimethyl barbituric acidin aqueous solutions and biological pH, using cyclic voltammetry method. The results showed that the electrochemically generated compounds in leaves extract of lemon verbena and the flowers extract...
Our aim in this study was to provide further support to the hypothesis that phenolic compounds may play an important role in the anticarcinogenic properties of olive oil. We measured the effect of olive oil phenols on hydrogen peroxide (H(2)O(2))-induced DNA damage in human peripheral blood mononuclear cells (PBMC) and promyelocytic leukemia cells (HL60) using single-cell gel electrophoresis (c...
objective(s): in food industry, the inhibition of tyrosinase is very important, because this enzyme catalyzes the oxidation of phenolic compounds found in fruits and vegetables into quinones, which contribute in undesirable color and taste of fruits and vegetables. teucrium polium l. var. gnaphalodes (lamiaceae), a wild-growing flowering plant that has many applications in food preparations and...
in the present study the volatile organic compounds of e. azerbaijanica rech.f. were identified. phytochemical assessment of meoh extract of aerial parts of this plant was also performed and its free radical scavenging properties was evaluated. the essential oil of the air-dried aerial parts was obtained by hydro-distillation using a clevenger type apparatus. the oil was then analyzed by gas ch...
background and objectives: phlomis olivieri benth. (lamiaceae) is a medicinal plant widely distributed in iran. in the present study, we have investigated the phytochemical constituents, antioxidant activity and general toxicity potential of the aerial parts of this species. methods: silica gel (normal and reversed phases) and sephadex lh-20 column chromatographies were used for isolation of co...
Anthocyanins (Anths) in olive (Olea europaea L.) fruits at different degrees of pigmentation were assessed nondestructively by measuring chlorophyll fluorescence (ChlF). The method is based on the comparison of the ChlF excitation spectra from olives with different pigmentation from green to green-red, reddish-purple, and purple. The logarithm of the ratio between the fluorescence excitation sp...
