Chemical constituents of Allium stipitatum regel (persian shallot) essential oil
A. stipitatum (Synonym: A. hirtifolium) or Persian shallot from Amaryllidaceae family with indigenous name of ''Mooseer'' is one of the important edible Alliums in Iran. It is native and endemic from northwestern to southern of Iran and grows as a wild plant in the Zagross Mountains at high elevations of different provinces with the climate of very cold to moderate cold. In this study, essential oil constituents of A. stipitatum were investigated through gas chromatography/mass spectrometry (GC-MS) technique. After obtaining the chromatograms and mass spectra, the essential compounds of the essential oil were determined. As shown 1-Butene,1-(methylthio)-(Z) (18.21%), Methyl methylthiomethyl disulfide (8.41%), Dimethyl tetrasulfide (6.47%), Piperitenone oxide (4.55%) were the most abundant components and comprised 37.64% of the essential oil (Figure 1). While 2,5-Diethylthiophene (0.07%) and n-Nonanal (0.06%) were detected in lower amounts. The presence of compounds showed mono-sulfur (22.42%), disulfide (1.81%), tri-sulfur (13.57%) and tetra-sulfur compounds (6.47%). The results indicated that the highest amount of sulfur compounds is related to mono-sulfur compounds
Anti-platelet aggregation assay and chemical composition of essential oil from Allium atroviolaceum Boiss growing in Iran.
Plants belonging to genera Allium have widely been acquired as food and medicine. Their wide use was mainly
due to the medicinal properties attributed to these plants over the centuries, lately supported by epidemiological
and research studies. In this study, essential oil constituents of Allium atroviolaceum growing in Shahr-e-kord,
Iran, were investigated through gas chromatography/mass spectrometry (GC-MS) technique. In this essential oil
two major constituents were trisulfide, di-2-propenyl (26.85%) and diallyl disulphide (10.98%) while trans-2-(2-
pentenyl) furan (0.02%) and Limonene (0.06%) have been identified in lower amounts. The in-vitro antiplatelet
activity of essential oil was evaluated, using arachidonic acid (AA) and adenosine diphosphate (ADP) as the
platelet aggregation inducers. The results showed that essential oil of Allium atroviolaceum with IC50; 0.25
mg/ml and 0.47 mg/ml inhibited in-vitro platelet aggregation induced by AA and ADP respectively
Entinociceptive effects of Euphorbia helioscopia extract on Balb/c mice
Background and aims: Euphorbia helioscopia has multiple pharmacological activities, such as antibacterial, antiviral, antifungal,anticancer and/or antitumor, allelopathic, anti-allergic and anti-asthmatic, antioxidant, antinociceptive effect. The aim of the study was to evaluate the antinociceptive activities of Euphorbia helioscopia extract in Balb/c mice, as well as the total flavonoids, phenolic contents, and antioxidant activities of the extract.
Methods: In this study, 90 Balb/c mice were randomly designated into 9 groups. Group 1 received normal saline, groups 2 to 7 received different doses of the E. helioscopia hydroethanolic extract (i.e., 0.05, 0.1, 0.2, 0.4, 2, & 8 mg/kg, i.p.).In addition, groups 8 and 9 received naloxone (1 mg/kg) and extract (8 mg/kg) plus naloxone (1 mg/kg), respectively (Naloxone was injected 15 minutes after extract administration). Then, pain response was evaluated for 30 minutes after the injection of 20 µL formalin (1.5%) in the plantar surface of the mice foot. Further, the beta-carotene-linoleate method was used for measuring antioxidant capacity. Finally, total phenolic and flavonoid content were measured based on Folin-Ciocalteu colorimetric and aluminum chloride colorimetric methods, respectively.
Results: Total phenol and flavonoid content were 49.43 ± 1.8 mg GAE/g dried extract and 30.19 ± 1.96 mg rutin/g dried extract, respectively. Our results showed that during the first 5 minutes (the acute pain step), a significant difference (P<0.05) was observed between the control group and the group which received the E. helioscopia hydroethanolic extract (8 mg/kg). In the next 25 minutes (the chronic pain step), a significant difference (P<0.05) was found between the control group and the group which received 0.1 and 8 mg/kg doses of the extract. Based on the results, naloxone was unable to reverse the antinociceptive effects of the extract and the maximum antioxidant activity of the extract was 1.641 mg/g of rutin equivalent.
Conclusion: In general, this study supports the use of the E. helioscopia extract in folk medicine as the analgesic agent and calls for further investigations regarding elucidating its mechanism of action. Eventually, our findings revealed that the extract of E. helioscopia possessed either antinociceptive or anti-oxidative activities.

Chemical compositions of essential oil and antioxidant activity of dragonhead (Dracocephalum moldavica) in sole crop and dragonhead- soybean (Glycine max) intercropping system under organic manure and chemical fertilizer
Organic manure can be used as an alternative for chemical fertilizers in sustainable agriculture. In addition, compared with sole cropping systems, intercropping is a promising approach for the crop production due to its lower reliance to chemical fertilizers. In this study, grain yield of soybean and biomass, chemical compositions and antioxidant activity of dragonhead essential oil in sole crop and dragonhead-soybean intercropping system under organic and chemical fertilizers were investigated. Land equivalent ratio (LER) was calculated as well. Results indicated intercropping and application of organic manure, increased soybean grain yield and dragonhead biomass. The LER value for soybean: dragonhead with ratios of 1:1 and1:2 under organic manure was greater than 1, indicating superiority of intercropping versus sol crop systems. GC–MS analysis showed that geranial, geranyl acetate, neral and piperitone were major compounds of dragonhead. The geranial and neral contents were increased in sole cropped dragonhead with application of chemical fertilizer, while the piperitone content was enhanced in sole cropped plants fertilized with organic manure. The highest of geranyl acetate content was observed in intercropped dragonhead plants fertilized with chemical fertilizer. Addition of organic manure lead to increase the antioxidant capacity of dragonhead in intercropped plots. The highest antioxidant activity of dragonhead (IC50 = 1.45 μgmL−1) was observed in one row of soybean + two rows of dragohead treated with organic manure. Overall, one row of soybean + two rows of dragohead with use of organic manure was more productive and had the highest LER value, antioxidant activity and a large amount of chemical compositions of essential oil. Thus this treatment could be adopted by the medicinal plant growers for appropriate production of dragonhead. © 2018 Elsevier B.V

Medicinal plants: Past history and future perspective
Human societies have been in close contact with their environments since the beginning of
their formation and used the ingredients of the environment to obtain food and medicine.
Awareness and application of plants to prepare food and medicine have been realized through
trial and error, and gradually human became able to meet his needs from his surroundings.
Information about medicinal plants has long been transmitted gradually and from generation
to generation, a human knowledge has gradually become complete with the formation of
civilizations and the provision of more facilities. Medicinal plants are used as a medical
resource in almost all cultures. Ensuring the safety, quality and effectiveness of medicinal
plants and herbal drugs very recently became a key issue in industrialized and developing
countries. By standardizing and evaluating the health of active plant-derived compounds,
herbal drugs can help the emergence of a new era of the healthcare system to treat human
diseases in the future. Awareness of traditional knowledge and medicinal plants can play a
key role in the exploitation and discovery of natural plant resources. In order to maintain
this knowledge, comprehensive approach and collaboration are needed to maintain historical
records on medicinal plants and use these resources in favour of human beings, before they
are destroyed forever. Therefore, this review was conducted to investigate and describe the
process of using medicinal plants throughout history. This review focuses on the recent
various important challenges in quality evaluation of medicinal plants in the authenticity,
efficacy, toxicity and consistenc

Anchusa italica extract: phytochemical and neuroprotective evaluation on global cerebral ischemia and reperfusion
Stroke is the third leading cause of mortality and disability in industrial countries. Treatment with herbs with antioxidant properties has been reported to be an alternative to the conventional treatments. This study was conducted to investigate the effect of Anchusa italica extract on hippocampal injury induced by transient global cerebral ischemia and reperfusion in the rat. To do so, 50 rats were randomly assigned to five groups; control, sham, ischemia, and 50 or 100 mg/kg of Anchusa italica treated animals. Ischemia was induced by occlusion of carotid artery for 30 minutes. Afterward, behavioral tests and biochemical analyses were conducted. Induction of ischemia/reperfusion caused a decline in learning and passive avoidance memory in rats. Moreover, Anchusa italica caused an increase in learning and improved the passive avoidance memory. Induction of ischemia/reperfusion caused a decrease in the antioxidant capacity of the brain and serum as well as an increase in the malondialdehyde of the brain and serum. Anchusa italica led to an increase in the antioxidant capacity of the brain and serum and decrease in the malondialdehyde of the brain and serum. Overall, because of its protective effects on spatial memory, passive avoidance learning, antioxidant capacity, and lipid peroxidation during ischemia/reperfusion, Anchusa italica might be beneficial in ischemic patients
