Dyes are one of the most widely used components in different industries. Recently much attention has been focused on the replacement of natural pigments instead of synthetic colors. One of the most important sources for the production of natural pigments are medicinal plants that small number of them used as industrial and some of them are traditionally used. The worldwide demand for natural dyes increases nowadays due to environmental and echo friendly of them. Many of the plants used for dye extraction are classified as medicinal and some of these have recently been shown to possess remarkable antimicrobial and antiinflamtory activities. The present review describes important information about dye-yelding herbs and their medicinal properties.

Basil (Ocimum basilicum), a member of Lamiaceae family, is used in traditional Iranian medicine. Essential oils of basil leaves are composed of phenylpropanoids which are important in treatment of headaches, diarrhea, coughs, warts, worms and kidney malfunctions. The most important phenylpropanoid compounds contain eugenol, chavicol, methyl eugenol, methyl chavicol, myristicin, methyl cinnamat and elemicin. Biosynthesis of phenylpropanoids that passes from shikimate pathway, are regulated by an enzyme group. Phenylalanine amonia-lyase (PAL), cinnamate 4-hydroxylase (C4H), 4-coumarate CoA ligase (4CL), P-coumarate 3-hydroxilase (C3H) and O-methyltransferases (EOMT, CVOMT, COMT) are known as key enzymes regulating at production of phenylpropanoids. The phenylpropanoids are also produced in the area of stress conditions and maintained the plant against biotic and abiotic stresses. The purpose of this study is introducing Basil and its medicinal usages in Iran and an overview of the phenylpropanoid biosynthesis as an important part of the essence in basil and its evaluation of agronomic characteristics.

Results: The results revealed a significant decrease in cauda epididymal, testicular sperm counts and daily sperm production, also percent of sperm-progressive motility in comparison with control group (p≤ 0. 05). Conclusion: Our results of this study show that GSHE causes significant decrease in the sperm motility, count and daily sperm production without any change in body and accessory sex glands weight.

Background: There is an increasing interest in identifying potent cancer preventive and therapeutic agents. Silymarin is a flavonoids complex extracted from the milk thistle (Silybum marianum L. ) seeds. Silymarin was found clinically successful in the treatment of various liver diseases. Silymarin is in the focus of cancer researchers due to its high antioxidant properties. Objective: The present study was aimed to investigate the effect of silymarin on 4T1 cells and compared with taxol. Methods: 4T1 cell line (BALB/c mouse mammary tumors) was cultured in RPMI medium containing FBS 10%. Cells were incubated with 5% CO2 in presence of different concentration of silymarin (25-50-75-100-125 µ g/ml), taxol (1. 25-2. 5-5-10-20 nM) and combination of silymarin and taxol separately for 24, 48 and 72 hours. Cell viability was assessed using trypan blue and MTT staining. The cells morphology was studied using fluorescent dye (Hochest, propidium iodide). Results: Silymarin and taxol showed significant cytotoxic effects on breast cancer cell in a dose and time dependent manner. Condensation and deformation of the nuclei were also observed similarly for both treatments. In combination treatment silymarin enhanced the sensitivity of 4T1 cells to taxol in all doses. Conclusion: The cytotoxic effect of silymarin on mouse mammary tumors was comparable to taxol cytotoxicity. Treatment cells with combination of silymarin and taxol improved the cytotoxic effect of taxol.

Background: Cisplatin is an anti-cancer drug used in chemotherapy. The side effects of this drug include anoretic, nausea, decrease in genital gland function, azoospermia and oligospermia.

Methods: 60 hyperlipidemic type 2 diabetic patients were randomly allocated to C. colocynthis and placebo groups, but only 28 patients in each group completed the study. The patients in C. colocynthis and placebo groups were treated with processed C. colocynthis (100 mg) and placebo capsules (100 mg) three times a day respectively for 1 month. The fasting blood glucose, cholesterol, LDL, HDL, and triglyceride levels as primary outcome and aspartate transaminase, alanine transaminase and creatinine levels as secondary outcome were measured in both groups at the baseline and the endpoint. Results: In the C. colocynthis group fasting blood glucose, cholesterol and LDL levels were significantly reduced at the endpoint compared with the baseline. There were no significant changes in any blood parameters in C. colocynthis group compared with placebo at the endpoint. There were no gastrointestinal, liver and kidney function adverse effects during the study in both groups. Conclusion: The results suggest that processed C. colocynthis fruit extract may be a safe anti-hyperglycemic and anti-hypercholesterolemic agent in hyperlipidemic type II diabetic patients.

Background: rhizobacteria are specific group of soil microorganisms that aggressively colonize the rhizosphere and rhizoplane, and substantially improve plant growth and efficiency via direct or indirect mechanisms. Objective: To investigate the growth promoting effects of rhizobacteria strains on cuttings growth and variations of essential oils content and yield in Salvia officinalis. Methods: In this research, different rhizobacteria including Pseudomonas putida (strains 41 and 159) and fluorescence (strain 23) with different growth promoting characteristics was used first on stem cuttings and later on aerial parts of S. officinalis L. (with final concentration of 109 CFU/ml). The essential oils were isolated from aerial parts of the plants by hydro-distillation method and then subjected to GC and GC-MS apparatus to determine the oil constituents. Results: Results showed that the dry weight of above and below ground parts of plants were increased in response to employed rhizobacteria inoculation. The highest root and leaf dry weight were observed in plants treated with Putida strain 159 which is caused increase of 45% and 33% compared to control untreated plants, respectively. Also, the highest essential oil yield was obtained in plants treated with putida strains, and the lowest of that was gained in control plants and also plants treated with fluorescence strain. The most abundant essential oil components were cis-Thujone, camphor, 1, 8-cineol, camphene, α-pinene, viridiflorol, α-humulene, borneol and trans-meta-mentha-2, 8-diene. Conclusion: Results from the current research indicate the plants inoculation with rhizobacteria had positive impact only on the major constituents of the essential oil compared to controls.

Background: Thymus kotschyanus Boiss. & Hohen. is an Iranian medicinal plants that grows in different areas of Iran such as Mazandaran, Gilan, Azarbayejan, Kurdistan and Tehran. Objective: The objective was to identify the essential oil content and composition in 15 Iranian populations of T. kotschyanus. Methods: The essential oils content and composition of 15 Iranian populations of T. kotschyanus were studied in a randomized complete block design (RCBD) with three replications. The aerial parts of thyme populations were harvested in the full blooming stage. The essential oils contents were obtianed by clevenger apparatus. For accurate measurement of the essential oils compounds, the oil samples analyzed by gas chromatography (GC) and gas chromatography coupled to mass spectrometry (GC– MS). Results: The results showed that the populations of T. kotschyanus had significant (p<0. 01) differences in respect of essential oil contents. The highest essential oil content was found in the populations of Tehran, East Azarbayjan-I and East Azarbayjan-IV. The maximum thymol content was identified in the Kordestan-I population (40. 42%) and the highest content of carvacrol was related to Kerman (33. 08) and Zanjan-III (30. 49%) populations, respectivily. Also, the thyme populations had significantly (p<0. 01) differences in essential oil compositions except of carvacrol. Generally, 23 compounds in the essential oils were identified. The main constituents were carvacrol, thymol, borneol, 1. 8-cinole, cymne (ortho(, carvacrol methyl ether, (z)caryophyllene, camphor, and linalool. Conclusion: Although, the populations of T. kotschyanus were planted in the same ecological and agronomical conditions, they had significant differences in terms of phytochemical traits, which probably could be due the genetic factors.

Background: The genetic diversity among plants derived from tissue culture is called somaclonal variation, which provides a valuable source of genetic variation for the improvement of medicinal plants. Objective: The present study was conducted to investigate the efficiency of molecular markers in detection of somaclonal variation and to assess the importance of DNA methylation in occurrence of genomic changes. Methods: The genomic DNA of a normal plant and eight abnormal regenerated plants from calluses cultured in different conditions were extracted using modified Delaporta method. The AFLP procedure was performed with application of two different double digestion methods using restriction enzymes. The digested fragments were ligated to appropriate adaptors and amplification was carried out using appropriate primers. Also percentage and component of essential oil were indicated by GC/MS analysis. Results: Analysis of banding patterns showed high differences in amount of polymorphism detected between two different double digestion methods. According to the results of cluster analysis based on the Jaccard's similarity coefficient, all tested plants divided into two main group. While the first group contained only normal sample, other abnormal samples were placed in the second group. Phytochemical analysis showed that the important secondary metabolites such as Limonene, Fenchone, Estragole, Anethole didn’ t produce in invitro culture condition. In contrast some metabolites like Cineol, Terpineol, 2, 4 Decadienal produce just in invitro culture. Conclusion: The results indicated that the used method has the potential to be used for assessment of somaclonal variations in regenerated plants. Additionally, considering characters of served enzymes in this study, phenotypic variations in abnormal plants that are resulted from somaclonal variation can be related to genome methylation.
