- In this study, the seed oil content and fatty acid (FA) profile of 21 populations from 16 wild Salvia species of Iran were analyzed by GC. Patterns of chemical variations of the oils among species were identified via numerical analyses and also the taxonomic status of the infrageneric grouping was outlined in the genus. Salvia species were scored based on the contents of main FAs using principal coordinate analysis (PCO). The results showed that the total oil content in the seeds varied significantly, and ranged from 6.68 to 38.53% dry weight. alpha-Linolenic (18:3 omega 3, 1.69 -53.56%), linoleic (18:2 omega 6, 13.04 - 60.64%), oleic (18:1 omega 9, 6.15 - 27.06%), palmitic (16:0, 3.77-9.27%), and stearic (18:0, 1.78 - 3.05%) acid were identified as five major FAs in the oils. The amount of omega-3 and omega-6 FAs ranged between 1.90 - 53.80% and 13.46 - 60.83% of total FAs in the seed oils, respectively. The results confirmed that FA profiles were distinctive among the species and that they can be used as chemotaxonomic markers. The discrimination of Salvia species according to their botanical classification at intersectional level was supported. In general, seed oils of Salvia species were rich sources of polyunsaturated FAs, except in linoleic and alpha-linolenic acid, and may be valuable for food and pharmaceutical industries.

- The Apiaceae family includes some of the most known medicinal, food and spice species in the world some of which have been used by humans since antiquity. Local people in different regions use many species of the family but the information regarding their uses is scattered. Traditionally used species are good candidates for bioprospecting. Combining traditional uses with phylogenetic data helps in selecting species for bioprospecting. In the present study, an ethnobotanical literature review was conducted to outline a comprehensive overview of the ethnobotanical importance of the family in Iran. To highlight the most ethnobotanically used groups in the family, ethnobotanical data were overlapped with generic phylogeny tree of the subfamily Apioideae. In total, 72 species (17.27%) from 42 genera (33.87%) were found to have ethnobotanical uses. Main uses of the family members were medicinal purposes (67.30%) followed by culinary (25%) and ethnoveterinary (11.11%) uses. Two categories of potential species groups for further bioprospecting investigations have been identified based on the phylogenetic analysis. Based on the findings of the present study, phylogenetic analysis can help in identifying potential groups for bioprospecting studies. More rigorous phylogenetic analysis that combines chemotaxonomy data, ethnomedicinal data and phylogenetic data are necessary to pinpoint exact lineages for specific medicinal properties.

- In this study, physiological and molecular responses of sage (Salvia officinalis) to silver nanoparticles (SNPs) were studied. It is supposed that sage oxidative responses can be activated to overcome the negative effects of SNPs. Results showed the penetration of SNPs via leaf epidermis into the parenchyma cells after foliar application. A significant decrease of photosynthetic pigments and increase of cell injury indicators, the activity of enzymatic antioxidants and also the content of non-enzymatic antioxidants were observed after exposure of sage plants to 50 and 1000 mg l(-1)SNPs compared to control plants. Phenolic compounds generally increased, but not in linear response to the dose level. The most abundant phenolic acid, rosmarinic acid (RA), increased more than eightfold at 100 mg l(-1)SNPs. Furthermore, the content of RA, salvianolic acid A and B was positively correlated with the activity of phenylalanine ammonia-lyase and RA synthase, but not with tyrosine aminotransferase. It could be concluded that the content of phenolic compounds increased in response to lower SNPs concentrations (50 and 100 mg l(-1)). However, the oxidative stress responses continued above these concentrations.
