- چکیده:
- چکیده انگلیسی: Ducrosia anethifolia (DC.) Boiss. is belongs to the Apiaceae family. It is one of the three species of Iranian Ducrosia Boiss. species growing wild in several areas of the country. In this research, we extracted the essential oil and it analyzed by GC/MS. The analysis of essential oil from leaves of D. anethifolia about 19 constituents was identifed and percentage composition was determined (94.9%). The major constituents identified by this method were α-pinene (70.3%), β-myrcene (6.9%), β-pinene (6.3%), limonene (4.9%). So, extracts of this species extracted by maceration method and antioxidant activity evaluated by 1,1-diphenyl-2-picrylhydrazyl (DPPH•). Results showed that antioxidant activity of D. anethifolia in ethanolic and ethyl acetate extracts are less than Butylated hydroxytoluene (BHT) as a synthetic antioxidant which used for positive control. Although, antioxidant activity of ethanolic extract is more than ethyl acetate extract, but inhibitory power of this extracts is low.

- چکیده:
- چکیده انگلیسی: The aim of the present work was to investigate the ability of Cocopeat to remove of lead (II) from aqueous solutions. The effects of different parameters such as particle size, adsorbent dosage, pH, contact time, agitation speed and concentration on the removal process has been investigated. The maximum removal of lead ion (92.5%) took place in the pH range of 4 contact time in 30 minutes and initial concentration of 30 mg.L-1. Results indicated that the Langmuir model gave a better fit to the experimental data in comparison with the Freundlich equation. The process followed pseudo-second-order kinetics.

- چکیده:
- چکیده انگلیسی: Objective: Eucalyptus (Fam. Myrtaceae) is a medicinal plant and various Eucalyptus species possess potent pharmacological actions against diabetes, hepatotoxicity, and inflammation. This study aims to investigate essential oil compositionfrom leaves and flowers of E. microthecaand E. viminalisleavesgrowing in the Southeast of Iran.
Materials and Methods: The aerial parts of these plants were collected from Zahedan, Sistan and Baluchestan province, Iran in 2013.After drying the plant materials in the shade, the chemical composition of the essential oils was obtained by hydro-distillation method using a Clevenger-type apparatus and analyzed by GC/MS.
Results: In the essential oil of E. microtheca leaves, 101 compounds representing 100%, were identified. Among them, α-phellandrene (16.487%), aromadendrene (12.773%), α-pinene (6.752%), globulol (5.997%), ledene (5.665%), P-cymen (5.251%), and β-pinene (5.006%) were the major constituents. In the oil of E. microtheca flowers, 88 compounds representing 100%, were identified in which α-pinene (16.246%), O-cymen (13.522%), β-pinene (11.082%), aromadendrene (7.444%), α-phellandrene (7.006%), globulol (5.419%), and 9-octadecenamide (5.414%) were the major components. Sixty six compounds representing 100% were identified in the oil of E. viminalis leaves. The major compounds were 1, 8-cineole (57.757%), α-pinene (13.379%), limonene (5.443%), and globulol (3.054%).
Conclusion: The results showed the essential oils fromthe aerial parts of Eucalyptus speciesare a cheap source for the commercial isolation of α-phellandrene, α-pinene, and 1, 8-cineole compounds to be used in medicinal and food products. Furthermore, these plants could be an alternative source of insecticide agents.- انتشار مقاله: 22-08-1393

- چکیده:
- چکیده انگلیسی: Objective: Boerhaavia elegans L. (Nyctaginaceae) is a medicinal plant used for the treatment of kidney disorders, urinary tract disorders and blood purification in Baluch tribe. The aim of present study is to evaluate the antioxidant propertyof B. elegans species for the first time.
Materials and Methods: Different parts (leaf, stem and fruit) of the plant were extracted by using various solvents (water, methanol, chloroform and ethyl acetate) and evaluated for their antioxidant activity using DPPH (2, 2-diphenyl-1 picryl hydrazyl) and FRAP (ferric reducing antioxidant power) methods. In addition, total phenolic content was determined by Folin–Ciocalteu reagent.
Results: Antioxidant results were expressed as IC50. The antioxidant power in DPPH and FRAP assay were evaluated as shown in decreasing order: Methanolic extract > Aqueous extract > Ethyl acetate extract > Chloroform extract, for all parts of the plant. In both methods of antioxidant assay and Folin-Ciocalteu method, methanolic extract of leaf exhibited the highest activity and the most phenolic content IC50= 6.85ppm and 16.41 mg GA/g d w respectively. Total phenolic content had a positive relationship with antioxidant capacity in extracts and there was a high correlation (r=1.00, p<0.01) between antioxidant activities as determined by both antioxidant assays for various parts.
Conclusion: The results of the experiments showed that B. elegans extract had significant antioxidant effects. This high antioxidant activity may be linked to phenolic contents of the plant but complementary investigations are suggested in order to determine active elements.- انتشار مقاله: 24-12-1392

- چکیده انگلیسی: Objective: Scutellaria luteo-caerulea Bornm. & Snit. is one of the species of genus Scutellaria, within the family of the Lamiaceae, that is used for immune system stimulation and antibacterial effects in traditional medicine in Iran. The aims of this study were to analyze essential oils and mineral element contents of leaves of S. luteo-caerulea in flowering stage of development.
Materials and Methods: The essential oils were obtained by hydrodistillation of the leaves of S. luteo-caerulea and were analyzed by gas chromatography mass spectrometry (GC/MS). Moreover, microwave digestion with atomic absorption spectrophotometry were used for the mineral elements assay.
Results: Ninety-seven constituents were detected. Between them, the major components were trans-caryophyllene (25.4%), D-germacrene (7.9%), and linalool (7.4%). Determination of mineral elements showed that the highest minerals were Ca2+ (65.14±1.95 µg/ml) and K+ (64.67±3.10 µg/ml).
Conclusion: Presence of different essential oils and rich sources of Ca2+ and K+ candidate this plant as an auxiliary medication in different diseases, but more complementary researches are needed about its potency and side effects.- انتشار مقاله: 07-05-1392

- چکیده انگلیسی: Abstract
Objective: The current study summarizes the updated information concerning the ethnopharmacology, Phytochemistry, and pharmacology of Otostegia persica Boiss. (Lamiaceae), an endemic medicinal plant in south and southeast of Iran.
Materials and Methods: Information was collected through bibliographic investigation from scientific journals, books, theses, reports, and electronic search (databases SCOPUS, Google Scholar, Web of Science, and Science Direct). Moreover, documentation from unpublished resources and ethnobotanical surveys has been used. The present review covers the literature available from 2003 to 2013.
Results: In traditional systems of medicine, this plant is reputed for treating diabetes, arthritis, gastric discomfort, headache, rheumatism, sedative activities, regulating blood pressure, and hyperlipidemia. Phytochemical screening of active components and mineral element evaluation of this species have been reported. Several types of diterpenoids and flavonols including morin, kaempferol, and quercetin are identified from the plant. Most of the pharmacological activity of this plant resides in its flavonoid fraction which causes antimicrobial and antioxidant activities. Various pharmacological studies on O. persica show antimicrobial, antioxidant, anti-inflammatory, anti-diabetic, anti-aphid, and hepatoprotective activities.
Conclusion: Being an endemic plant of Iran, this species is an important medicinal herb which can be used for various purposes. This review might be helpful for scientists and researchers to find new chemical entities responsible for its claimed traditional uses and discover new lead compounds for diseases mentioned.- انتشار مقاله: 16-03-1392
