Abstract
OBJECTIVE A plethora of scientific evidence showed that several plant species from the genus Allium (Alliaceae) possess multiple therapeutic effects. Present paper aimed to examine the antioxidant and antihemolytic activities of the essential oil and methanol extract Allium rotundum L. through different in vitro assays. MATERIALS AND METHODS 1,1-diphenyl-2-picryl hydroxyl radical (DPPH), nitric oxide as well as hydrogen peroxide scavenging, Fe2+ chelating, reducing power and also hemoglobin-induced linoleic acid peroxidation assay systems have been utilized to examine antioxidant effects of these samples. Total amounts of phenolic and flavonoid contents were calculated. The antihemolytic effect was investigated against hemolysis induced by hydrogen peroxide in rat erythrocytes. Also, mineral contents of plant were evaluated by atomic absorption spectroscopy. RESULTS IC50 for DPPH radical-scavenging activity were 284 ± 11.64 for methanol extract and 1264 ± 45.60 µg ml-1 for essential oil, respectively. The extract has shown better reducing effects versus essential oil. The extract also demonstrated better activity in nitric oxide-scavenging activity. IC50 were 464 ± 19.68 for extract and 1093 ± 38.25 µg ml-1 for essential oil. The extract shows better activity than essential oil in Fe2+ chelating system. IC50 were 100 ± 3.75 for extract and 1223 ± 36.25 µg ml-1 for essential oil. The A. rotundum extract and essential oil showed significant H2O2 scavenging effects at dose-dependent manners. IC50 was 786 ± 29.08 mg ml-1 for essential oil. The amounts of eight elements were determined. The concentrations of elements were in the order: Mn> Fe> Zn> Cu> Ni> Cd. CONCLUSIONS The extract showed a higher antioxidant effect in all tested models including DPPH, nitric oxide, reducing power as well as iron chelating and antihemolytic activities than essential oil. The latter showed more potent antioxidant activity in scavenging H2O2 and lipid peroxidation model. Antioxidant activities of extract may be attributed at least in part, due to its phenolic and flavonoid contents.

Abstract
Diabetic retinopathy is one of the most common complications of diabetes. A plethora of literature indicates that oxidative stress may play a central role in the pathogenesis of diabetic retinopathy. One could thus hypothesise that antioxidant therapies may be protective for diabetic retinopathy. Anthocyanins are important natural bioactive pigments responsible for red-blue colour of fruits, leaves, seeds, stems and flowers in a variety of plant species. Apart from their colours, anthocyanins are known to be health-promoting phytochemicals with potential properties useful to protect against oxidative stress in some degenerative diseases. They also have a variety of biological properties including anti-inflammatory, antibacterial, anticancer, and cardio-protective properties. Some reports further suggest a therapeutic role of anthocyanins to prevent and/or protect against ocular diseases but more studies are needed to examine their potential as alternative therapy to diabetic retinopathy. The present article reviews the available literature concerning the beneficial role of anthocyanins in diabetic retinopathy.

Abstract
OBJECTIVES Hypericum (H.) spp. has been used in traditional medicine for their anticonvulsant effect for many years. In spite of many works on this genus, little is known about H. scabrum. In this work, anticonvulsant activity of H. scabrum was investigated. MATERIALS AND METHODS Anticonvulsant activity of aqueous extract was evaluated by pentylenetetrazole (PTZ) induced convulsion and picrotoxin induced convulsion. Also, nitric oxide radical scavenging was investigated as a possible mechanism involved. RESULTS Extract (125-500 mg kg-1, i.p.) significantly delayed the onset of PTZ induced convulsion. At 500 mg kg-1, 100% protection against mortality was observed. At this dose, it significantly prolonged the onset of picrotoxin induced convulsion in mice, too. It showed significant nitric oxide radical scavenging activity. CONCLUSIONS Mechanism of anticonvulsant activity may be through GABA and/or nitric oxide pathway.

Abstract
OBJECTIVES Artemisia (Asteraceae) contains more than 400 species. Many of the plants belonging to this genus are known to possess biological properties. In this study, antioxidant and antihemolytic activities of flavonoid rich fractions of A. tschernieviana Besser were evaluated. MATERIAL AND METHODS Plant aerial parts were extracted with 60% acetone. Extract was fractionated sequentially with hexane (HE), ethyl acetate (EA) and water (AQ). Antioxidant and antihemolytic activities of these fractions were assessed. Their antihemolytic activity was determined by H2O2 and cumene hydroperoxide induced hemolysis models. RESULTS AQ fraction showed very powerful activity in 1,1-disphenyl-2-picryl hydrazyl (DPPH) radical scavenging activity with IC50 = 0.12 +/- 0.01 microg ml(-1) that was better than controls (vitamin C, quercetin and butylated hydroxyanisole (BHA)). This fraction showed very powerful reducing power assay that was better than vitamin C (p < 0.01). EA fraction showed higher activity in scavenging nitric oxide with IC50 = 0.14 +/- 0.04 microg ml(-1). In iron chelating activity HE fraction showed the best activity (IC50 = 162.2 +/- 8.7 microg ml(-1)). In scavenging of hydrogen peroxide, AQ fraction showed better activity than control group. This fraction had higher phenol and flavonoid contents. EA fraction showed higher antihemolytic activity with IC50 = 728.8 +/- 29 microg ml(-1). CONCLUSIONS The fractions show very good activities in studied models. Aqueous fractions showed better activity than the others in nearly all tested models. These results can be useful as a starting point of view for further applications of A. tschernieviana aerial parts or its constituents in pharmaceutical preparations after performing clinical in vivo researches.

Abstract
OBJECTIVES Eryngium (E.) caucasicum was found as a new cultivated vegetable plant in northern Iran and used in several local foods. Little information is available on biological properties of E. caucasicum. In this work antioxidant activity of flavonoid-rich fraction of this plant was investigated by eight in vitro assay systems. MATERIALS AND METHODS 1,1-diphenyl-2-picryl hydrazyl radical (DPPH), nitric oxide and hydrogen peroxide scavenging activities, Fe2+ chelating ability, reducing power and hemoglobin-induced linoleic acid peroxidation were used to evaluate antioxidant activities. Antihemolytic activities were evaluated against CuOOH and H2O2 induced hemolysis in rat erythrocyte. RESULTS IC50 for DPPH scavenging activity was 391.2 +/- 14.9, 706.6 +/- 22.3 and 779.7 +/- 16.7 microg ml(-1) for aqueous (AQ), ethyl acetate (EA) and n-hexane (HE) fractions, respectively. There was no difference between reducing power of AQ fraction activity and vitamin C (p > 0.05). IC50 for NO radical-scavenging activity was in order of AQ (133.5 +/- 6.2 microg ml(-1)) > EA (350.1 +/- 14.8 microg ml(-1)) > and HE (639.9 +/- 21.7 microg ml(-1)) fractions, respectively. Extracts showed weak Fe2+ chelating ability. HE fraction showed better activity (173.5 +/- 9.6 microg ml(-1)). Extracts exhibited weak hydrogen peroxide scavenging activity but exhibited very good antioxidant activity against the hemoglobin-induced linoleic acid peroxidation. There was no significant difference between AQ fraction and vitamin C (p > 0.01). Fractions delayed the onset of the CuOOH induced hemolysis. AQ fraction showed very high total phenol and flavonoid contents which was higher than other fractions. High phenol and flavonoid content of AQ fraction may lead to its better antioxidant activity. CONCLUSIONS E. caucasicum fractions exhibited different levels of antioxidant and antihemolytic activities in all tested models. These results can be useful as a starting point of view for further applications of E. caucasicum aerial parts or its constituents in pharmaceutical preparations.

Abstract
OBJECTIVES Ferula gummosa Boiss is native to central Asia. This plant has traditionally been used in the treatment of many diseases. The antihypoxic and antioxidant activities of Ferula gummosa roots were investigated. MATERIAL AND METHODS 1,1-diphenyl-2-picryl hydrazyl radical (DPPH), nitric oxide and hydrogen peroxide scavenging activities, Fe2+ chelating ability, reducing power and hemoglobin-induced linoleic acid peroxidation were used to evaluate antioxidant activities. Antihemolytic activity was evaluated by H2O2 induced hemolysis in rat erythrocytes. The total amount of phenolic compounds was determined as gallic acid equivalents and total flavonoid contents were calculated as quercetin equivalents from a calibration curve. RESULTS The extracts showed moderate antioxidant activity in some models. IC50 for DPPH radical-scavenging activity was 579.6 +/- 19.4 microg/ml. The extracts showed weak nitric oxide-scavenging activity between 0.1 and 1.6 mg ml(-1) but showed good Fe2+ chelating ability. IC50 was 895.5 +/- 24.1 microg/ml. The extract also exhibited low antioxidant activity in the linoleic acid model but were capable of scavenging hydrogen peroxide in a concentration dependent manner. Tested extract show moderate activity in H2O2 induced hemolysis in rat erythrocytes which was not comparable with vitamin C. CONCLUSIONS F. gummosa Boiss root showed different level antioxidant and antihemolytic activities. Biological effects may be attributed, at least in part, to the presence of phenols and flavonoids in the extract.

Abstract
OBJECTIVES Hypericum spp. (H.) has been used in traditional medicine for their sedative effect for many years. In spite of many works on this genus, little is known about H. scabrum. In this work antidepressant and its protective effect against hypoxia-induced lethality were evaluated. MATERIALS AND METHODS Antidepressant and its protective effects against hypoxia-induced lethality were evaluated. Antidepressant activity was determined by forced swimming test (FST) and tail suspension test (TST). Antihypoxic activities were determined by asphytic, haemic and circulatory hypoxia models in mice. Also, hydrogen peroxide scavenging activity and cumene hydroperoxide (CuOOH) induced hemolysis also were investigated. RESULTS At all tested doses H. scabrum significantly and dose dependently reduced the immobility periods in FST and TST. Also, extract showed statistically significant antihypoxic activities in three asphytic, haemic and circulatory hypoxia models in mice. The extract showed moderately good scavenging activity with IC50 = 518.8 +/- 20.7 microg ml(-1). Extract inhibited significantly CuOOH induced hemolysis in red blood cells (RBC). CONCLUSIONS H. scabrum aqueous extract showed remarkable antihypoxic and antidepressant effects thus, lend pharmacological justification to the use of the plant extract by traditional medicine practitioners. Mechanism of antidepressant activity of extract may be through nitric oxide pathway.

Abstract
OBJECTIVES Alcea hyrcana Grossh (A. hyrcana Grossh) (malvacea), is native to northern of Iran. Many of the plants belonging to the genus Alcea are known to possess ethnomedical and biological properties. In this study, antioxidant activities of methanolic extracts of flower, seed and leaves of Alcea hyrcana Grossh were evaluated by various antioxidant assays. MATERIAL AND METHODS 1,1-diphenyl-2-picryl hydrazyl radical (DPPH), nitric oxide and hydrogen peroxide scavenging activities, Fe2+ chelating ability, reducing power and hemoglobin-induced linoleic acid peroxidation test were used to evaluate antioxidant activities. The total amount of phenolic compounds was determined as gallic acid equivalents and total flavonoid contents were calculated as quercetin equivalents from a calibration curve. Total phenolic and flavonoid contents also have been determined. RESULTS All extracts showed good antioxidant activities. The A. hyrcana Grossh leaves extract exhibited strong ferrous chelating activity with IC50 = 0.11 +/- 0.01 mg ml(-1), nitric oxide radical scavenging with IC50 = 0.45 +/- 0.01 mg ml(-1) and better reducing power activity than other extracts. The seeds extract showed high scavenging activity against free radicals, including both the hydrogen peroxide and DPPH radicals. Only leaves extract had good activity in linoleic acid model. Seeds extract had significant higher total phenol (68.9 +/- 3.7 mg gallic acid equivalent/g of extract powder) and leaves had higher flavonoids contents (28.3 +/- 2.6 mg quercetin equivalent/g of extract powder) than other parts. CONCLUSIONS The leaves, seed and flower extracts of A. hyrcana Grossh exhibited good but different levels of antioxidant activity in all the models studied. The extracts had good iron chelation, H2O2 and nitric oxide scavenging activities. Antioxidant activities may be attributed, at least in part, to the presence of phenols and flavonoids.

Abstract
OBJECTIVES The Ferula genus (Umbelliferae) is a rich source of gum-resin and is much utilized in folklore medicine. This study is designed to examine antioxidant and antihaemolytic activities of Ferula foetida regel flower, stem and leaf extracts. MATERIALS AND METHODS 1,1-Diphenyl-2-picryl hydrazyl radical (DPPH), nitric oxide and H2O2 scavenging activities, Fe2+ chelating ability, reducing power and hemoglobin-induced linoleic acid peroxidation were used to evaluate antioxidant activities. Antihaemolytic activity was evaluated by H2O2 induced hemolysis in rat erythrocyte. Total phenolic compounds were determined as gallic acid equivalents and total flavonoid contents were calculated as quercetin equivalents from a calibration curve. RESULTS The leaf aqueous-ethanol extract showed the highest activity in DPPH radical scavenging activity. All extracts showed weak nitric oxide scavenging activity. The stem extract had better activity in nitric oxide scavenging model than the other extracts (IC50 = 896.9 +/- 21.9 microg ml(-1)), but it was not comparable to quercetin (p < 0.001). The leaf extract exhibited better H2O2 scavenging and Fe2+ chelating activity than the other parts. The extracts exhibited good antioxidant activity in linoleic acid peroxidation test but were not comparable to vitamin C (p < 0.001). Extracts showed weak reducing power activity. The stem extract showed better antihaemolytic activity than the flower and leaf. The flower extract had higher phenolic contents. The extracts exhibited different levels of antioxidant and antihaemolytic activities in all tested models. CONCLUSIONS This study showed remarkable antioxidant and antihemolytic activities in Feruia foetida. Biological effects may be attributed to the presence of phenols and flavonoids in the extract. It is very promising for further biochemical experiments.

Abstract
OBJECTIVES Biebersteinia multifida is a common herb known in Iran. Its roots have been used locally in folk medicine of western region of Iran in the treatment of many diseases. The antioxidant activity and its inhibition of erythrocyte hemolysis were investigated. MATERIAL AND METHODS 1,1-diphenyl-2-picryl hydrazyl radical (DPPH), nitric oxide and hydrogen peroxide scavenging activities, Fe2+ chelating ability, reducing power and hemoglobin-induced linoleic acid peroxidation were used to evaluate antioxidant activities. Antihemolytic activity was evaluated by H2O2 induced hemolysis in rat erythrocyte. The total amount of phenolic compounds was determined as gallic acid equivalents and total flavonoid contents were calculated as quercetin equivalents from a calibration curve. RESULTS Root had higher phenol contents (80.1 +/- 3.1 mg ml(-1)) and showed highest activity in DPPH radical-scavenging activity (95.9 +/- 3.2 microg ml(-1)). It also showed better reducing power than other parts. In Fe2+ chelating, leaf extract was the most potent (789 +/- 33 microg ml(-1)). Extracts exhibited good H2O2 scavenging in a concentration dependent manner. All extracts exhibited good protection against hemoglobin-catalyzed peroxidation linoleic acid system. In nitric oxide scavenging model, root extract showed the best activity (696 +/- 2.7 microg ml(-1)). Root and leaf extracts contained total phenol and flavonoids contents than other extracts. Tested extracts show weak activity in H2O2 induced hemolysis in rat erythrocyte which was not comparable with vitamin C. CONCLUSIONS Biebersteinia multifida extracts exhibited different levels of antioxidant and antihemolytic activities in all tested models. Biological effects may be attributed, at least in part, to the presence of phenols and flavonoids in the extracts.

Abstract
OBJECTIVES Pistacia lentiscus has traditionally been used in the treatment of many diseases. Its resin was investigated for its mineral contents, anti-inflammatory and antioxidant activities in rats. MATERIAL AND METHODS Inhibition of carrageenan induced edema was used to evaluate anti-inflammatory activity. Fe2+ chelating ability, 1,1-diphenyl-2-picryl hydrazyl radical (DPPH) and nitric oxide scavenging activities were used to evaluate antioxidant activities and mineral contents were determined by atomic absorption spectroscopy. Gallic acid content was determined by HPLC. RESULTS Resin produced statistically significant inhibition of edema at all doses when compared to the control groups. A 100% inhibition of inflammation was observed at 800 mg/kg i.p. Resin exhibit no toxicity up to 3 g/kg body weights i.p. in mice. Weak DPPH and nitric oxide scavenging activities were observed but showed good Fe2+ chelating ability (IC50 = 162 microg ml(-1)). The amount of elements was decreased in the order: Cu > Fe, Zn > Mn > Ni, Cd. Gallic acid content was 0.1 mg/g resin. CONCLUSIONS These experimental data support the use of Pistacia lentiscus resin as an antiinflammatory and antioxidant agent.

Abstract
Iron chelating activity of 16 extracts from 11 medicinal plants has been determined to find alternative sources with lower side effects in thalassemic patients. Thalassemia is characterized by iron overload and chelation therapy reduces iron-related complications and thereby improves quality of life and overall survival. Because of poor oral bioavailability, short plasma half-life and severe side effects of available chelators, this screening may be useful in this area. Extracts were prepared by soaking dry material of the selected plant in appropriate solvent. Phenol and flavonoid content of the extract were measured by Folin Ciocalteu and AlCl3 colorimetric assays. Phenol content of the extracts varied between 8.4-194.9 mg g(-1) of extract. The highest chelating activity was found in aerial parts of Leonurus cardiana and Grammosciadium platycarpum which had high amount of phenol and flavonoid contents. All extracts contained various amount of flavonoids from 5.9 to 90.9 mg g(-1) of extract. Weak correlations were found between phenolic and flavonoids contents and iron chelatory activity with R2 = 0.40. Extracts with high phytochemicals and chelating activity can be candidate as a good source of new agents for thalassemic patients.

Abstract
Current research into free radicals has confirmed that plants rich in antioxidants play an essential role in the prevention of many diseases. The potential antioxidant activities of Pterocarya fraxinifolia bark and leaves investigated employing six in vitro assay systems. IC50 for DPPH radical-scavenging activities were 3.89 +/- 0.09 for leaves and 41.57 +/- 1.30 microg mL(-1) for bark, respectively. The leaf extract exhibited a good reducing power at 2.5 and 80 microg mL(-1) that was comparable with Vit C (p > 0.05). The extracts also showed weak nitric oxide-scavenging activity and Fe2+ chelating ability. The peroxidation inhibition of extracts exhibited values from 92 to 93% at 72nd h, almost at the same pattern of Vitamin C activity (p > 0.05). Based on higher total phenol and flavonoid contents in leaves, higher antioxidant activities were observed in leaf extract. In addition, chemical composition of leaf essential oil was determined. The major compound was bisabolol oxide A (23.6%). Sesquiterpenes and monoterpenes are the major compounds in leaves essential oil. Presence of these compounds may be a reason for the good antioxidant activity of leaf extract.

Abstract
In this study antioxidant activity of methanol extract of Sambucus ebulus L. flower was investigated employing various in vitro assay systems, i.e., DPPH and nitric oxide radical scavenging, hydrogen peroxide scavenging, reducing power, iron ion chelating power and linoleic acid. IC50 for DPPH radical-scavenging activity was 228 +/- 12 microg mL(-1). The extract showed very high activity in the reducing power assay that was comparable with positive control, vitamin C. The extract showed good nitric oxide-scavenging activity (IC50 = 309 +/- 14 microg mL(-1). It was found that antioxidant activity was dose dependent i.e., activity was increased with the increase of their concentrations. The extract showed very weak activity in iron ion chelating (IC50 = 1.3 +/- 0.07 mg mL(-1)). It is showed very good activity in scavenging of hydrogen'peroxide. IC50 for scavenging of extract was 59.5 +/- 3.3 mcirog mL(-1). The extracts exhibited no activity in linoleic acid model. The total phenolic content of flower was 56.3 +/- 2.81 mg gallic acid equivalent g(-1) of extract powder and total flavonoid content was 14.5 +/- 0.72 mg quercetin equivalent g(-1) of extract powder by reference to standard curve.
