This work was aimed to extract and characterise the essential oils presented in the leaves of Moringa Oleifera using supercritical fluid extraction (SFE) and compare the results against those using the conventional Soxhlet extraction method. The oils extracted were analysed using GC-MS. The compounds were identified according to their retention indices and mass spectra (EI, 70eV). The effects o...

An estimation procedure for biobased carbon content of polyethylene composite was studied using carbon-14 ((14)C) concentration ratios as measured by accelerated mass spectrometry (AMS). Prior to the measurement, additives and fillers in composites should be removed because they often contain a large amount of biobased carbon and may shift the estimation. Samples of resin with purity suitable f...

OBJECTIVE In continuation to the growing evidence for therapeutical potential of Desmostachya bipinnata (Linn) Stapf, the current pharmacological study was carried out to evaluate the diuretic and laxative activity of its hydro-alcoholic extract in rats. METHODS The hydro-alcoholic extract of D. bipinnata whole plant was prepared by using Soxhlet extractor and subjected to analysis by standar...

Macroalgae are one of potential sources for carotenoids, such as fucoxanthin, which are consumed by humans and animals. This carotenoid has been applied in both the pharmaceutical and food industries. In this study, extraction of fucoxanthin from wet brown seaweed Undaria pinnatifida (water content was 93.2%) was carried out with a simple method using liquefied dimethyl ether (DME) as an extrac...

Background: Ribes biebersteinii (Rb) is one of pharmaceutical plants which was used in traditional medicine for decreasing blood sugar. Objective: In this study, effect of aqueous fruit extract of Rb on blood sugar of rats was investigated. Methods: In this research 60 male Wistar rats were categorized randomly in 10 equal groups with two timeframes (7 & 14 days). Extraction of Rb was perfor...

In this study, high performance liquid chromatography (HPLC), ultraviolet (UV), thermagravimetric analyzer (TGA), pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS), and scanning electron microscope (SEM) were used as measurement techniques, contents of chemical composition, pyrolytic products, thermal stability, morphological characterization of Ginkgo biloba leaves (GBL) acted as the i...

Background: Spermatogonial stem cells (SSCs) transmit genetic information to the next generation. For successful transplantation of these cells, culture medium must be optimized. Objectives: This study investigated natural antioxidant grape seed extract (GSE) in comparison vitamin C SSCs. Methods: A Soxhlet extractor was used prepare ethanolic and acetonic extracts, Clevenger apparatus aqueous ...

Scrophularia genus belonging to the family of Scrophulariaceae, is a medicinal plant widely distributed in Iran. In the present study,the anti-malarial activity of different extracts of three Iranian endemic species of Scrophularia including S. frigida, S. subaphylla and S. atropatana, was screened by an in-vitro preliminary assay. The plant materials were extracted successively with n-hexane, ...
