Background: Dashtestan, with 6371 km2 area, is situated at 85 km in the east of Bushehr city. Influence of some important ecological factores, such as neighboring to the Persian Gulf, passing two rivers of dalaki and shapoor and also presence of southern continuation of Zagros Mountains are leading to high importance of region in plant biodiversity view point. Objective: Study on the medicinal plant flora of the region and introducing some information of folk medicine and the most useful medicinal species were objected here. Methods: All ancient regions of the Dashtestan were discovered using appropriate geographical maps and then the plant species were gathered from various localities respectively. Vernacular information of collected plants and their usages in the folk medicine were questioned from well experienced people. In final stage the collected plants were identified scientifically after deposition in the herbarium. Results: A total of 85 plant species representing 70 genera and 39 families are identified in the area. The most abundant families of the region are Asteraceae (10 species) and Lamiaceae (8 species) respectively, and the largest genera is Ziziphus (Rhamnaceae) with 6 species. The most folk medicine usage of them is in the remediation of digestive diseases. Conclusion: Traditional usage of medicinal plant is more accepted among the people of area. The most of medicinal herbs are used mainly in remediation of digestive diseases. Considering the culture of society and attention of people to medicinal plants, it may be an attractive object from the farmacological view point. Source

The aim of this study was to investigate antioxidant and antibacterial activities of ethanolic extract of Smyrnium cordifolium Boiss. the ethanolic extract was subjected to screening for its possible antioxidant activity. Namely DPPH free radical scavenging, FTC system and total phenolic compounds were used. Also, Antibacterial activity of ethanolic extract using Gentamicin and Tetracycline as the reference standards were tested against Bacillus subtilis, Enterococcus faecalis, Staphylococcus aureus, Staphylococcus epidermidis, Escherichia coli and Klebsiella pneumoniae. The results revealed good antioxidant activity of the extract. The ethanolic extract of S. cordifolium exhibited an antibacterial activity at different levels against strains reported as the causal agents of diseases and this extract inhibited Gram positive bacteria significantly higher than Gram negative bacteria. Observed antioxidant and antibacterial properties of ethanolic extract of the S. cordifolium in this study showed that this plant might be useful source for the development of new and more potent natural antioxidants and antibacterial. © 2010 Asian Network for Scientific Information.

The use of medicinal plants for the treatment of acne and other infectious skin diseases is very common. Here, pharmacological studies on the medicinal plants which may be effective in the treatment of acne and infective skin diseases published in the databases PubMed and Scopus from the beginning of the year 1980 to the end of April of the year 2013 have been searched and discussed. Keywords including medicinal plants, herbs, botanicals, phytomedicine, phytotherapy, herbal therapy and herbal medicine with dermatology, skin, acne vulgaris, antibacterial, antiviral, antifungal and antimicrobial were entered in the databases. Totally 56 articles concerning clinical and nonclinical studies were found. Afterward, the quality of each study was determined. Examples of such plants include Vitex agnus-castus, Ocimum gratissimum, Aloe vera , Solanum dulcamara, Commiphora mukul, Mahonia aquifolium, Melaleuca alternifolia, species of the genus Eucalyptus, Camellia sinensis and Allium sativum. Medicinal plants can have an important role in the treatment of acne and other infectious skin diseases. However, scant studies have been conducted in this field so far and more studies especially on the efficacy and safety of the plants' clinical use in humans are needed. Source

The present study explores the chemical constitution and antioxidant activity of the essential oils of the aerial parts of Artemisia dracunculus L. and the flower heads of Matricaria chamomilla L. GC-MS analysis revealed the presence of (Z)-anethole (51.72%), (Z)-β-ocimene (8.32%), methyleugenol (8.06%), limonene (4.94%) and linalool (4.41%) in Artemisia dracunculus and (E)-β-farnesene (24.19%), guaiazulene (10.57%), α-bisabolol oxide A (10.21%), α-farnesene (8.7%) and α-bisabolol (7.27%) in M. chamomilla L. The antioxidant activity (AOA) of the essential oils was investigated using DPPH • (2, 2'-diphenyl 1-picrylhydrazyl) free radical scavenging and β-carotene/linoleic acid methods. The essential oil EC 50 values were determined as 3.19±0.13 and 5.63±0.20 mg ml -1 for A. dracunculus and M. chamomilla, respectively. Further, the A. dracunculus L. essential oil (ADEO) and M. chamomilla L. essential oil (MCEO) were able to reduce the oxidation rate of soybean oil under accelerated conditions at 60 °C (oven test).

Background: The rice weevil, Sitophilus oryzae and rice moth, Corcyra cephalonica are major and cosmopolitan insect. Adults of S. oryzae (male and female) and both larvae are insatiable feeders on a great variety of grains. Objective: This study was conducted to estimate the insecticidal effect of essential oils from peppermint, Mentha piperita L. and black pepper, Piper nigrum L. against two major stored product insects. Methods: Essential oils from two species of plants were obtained by clevenger-type water distillation. The major compounds in these essential oils were identified using gas chromatography-mass spectrometry and their insecticidal effect was tested against adults of the rice weevil, Sitophilus oryzae L. and the 3rd instars larvae of rice moth, Corcyra cephalonica (St.). Results: The major compounds found in peppermint were menthol, isomenthone, limonene and cineole and in black pepper were limonene, α and β pinene and caryophyllene. Highest toxicities were observed against S. oryzae populations treated with M. piperita and P. nigrum essential oils with LC50 values of 85.0 and 287.7 μL/L air after 72 hours after commencement, respectively. In the case of C. cephalonica larvae, the LC50 values were 343.9 and 530.5 μL/L air for M. piperita and P. nigrum essential oils at 72 hours after commencement, respectively. These results are attributed to the compounds present in essential oils of M. piperita and P. nigrum. Conclusion: It was resulted that M. piperita and P. nigrum oils have insecticidal effects against S. oryzae and C. cephalonica. For this reasons, the selected plant oils have potential for development of novel insecticides. Source
