In vitro antioxidant activity of extracts lotus rhizome with different solvent by gradient extraction was determined. The yield and total phenolic content were 1,1-diphenyl-2-picrylhydrazyl hydrate (DPPH) radical scavenging assay β-carotene-linoleic acid conducted to assess the extracts. Results showed that butanol extract highest. order in as follows: water < petroleum ether chloroform ethyl a...

background: considering the wide consumption of some synthetic antioxidants and their probable negative health effects, in this study, the protective effects of satureja hortensis l. extracts in stabilizing soybean oil against oxidation at different concentrations (200 and 400 ppm) were tested. methods: the aerial parts of s. hortensis l. were collected from isfahan province and extracted with ...

Phlomis crinita is a plant species of the family Lamiaceae including more than 100 perennial herbs, shrubs, and sub-shrubs native to Mediterranean, Central Asia, India. This commonly good natural source various secondary metabolites. Therefore, present study was conducted determine phenolic content antioxidant activity hydromethanolic (PC ME) aqueous extracts AQE) aerial parts P. crinita. Total...

Objective(s): The purpose of this study was to evaluate variations in yields, volatile composition and biological activities of essential oils (EOs) obtained from the aerial parts of Zhumeria majdae collected from five localities of the south of Iran. Materials and Methods: The EOs were analyzed using gas chromatography and gas chromatography-mass spectrometry techniques. The antioxidant activi...

Objective(s): Mindium laevigatum is an endemic plant of Iran and Turkey and is widely used as blood purifier, antiasthma and antidyspnea in traditional medicine. Chemical composition of volatile materials of the plant and its antioxidant, antimicrobial and cytotoxic activities were reported in this study. Materials and Methods: Simultaneous distillation-extraction (SDE) and GC-Mass-FID analysis...

Heme detoxification through crystallization into hemozoin has been suggested as a good target for the development of screening assays for new antimalarials. However, comparisons among the data obtained from different experiments are difficult, and the IC(50) values (the concentrations of drug that are required to inhibit 50% of hemozoin formation) for the same drug vary widely. We studied the e...

The monohydroxy carotenoid from the moth Cerura vinula has been shown to be /?,/?-caroten-2-ol on the basis of electronic, infrared, proton magnetic-resonance, and mass spectra. On acid treat­ ment in the presence of molecular oxygen this carotenoid is dehydrogenated to 4',5-retro-ß,ßcaroten-2-one. The identification of /?„/?-caroten-2-ol by its retro product, its time course of acetylation, an...

Essential oils of two wild-growing Artemisia species collected from west of Iran during the flowering stage were obtained by hydro-distillation and analyzed by gas chromatography (GC) and gas chromatography/mass spectrometry (GC–MS). Under the optimum extraction and analysis conditions, 23 and 19 constituents were identified in A. fragrans and A. hausskenechtii which represented 92.96% and 90.2...

Coconut is widely used as a food source in producing countries, and during consumption, the waste that generated needs to be reduced through by-products processing ensure environmental sustainability. This study aimed assess functionality of (endo- mesocarp) coconuts at early mature stages. The aqueous ethanolic (50 100% ethanol water) extracts coconut were evaluated for DPPH radical scavenging...
