RESUMO
Background: Eremostachys laciniata is known as "Chelle-Daghi" in Iran and its rhizomes are used as an emollient to relieve rheumatoid arthritis
Objective: A phytochemical study was performed on 15 populations of Eremostachys laciniata to qualify the phytochemical variations
Methods: Plants collected from their natural habitats and dried rhizomes of E. laciniata were milled and then Soxhlet-extracted by MeOH, and then total phenols were determined calorimetrically by the Folin-ciocalteau reagent and iridoid glycosides were measured by TLC method
Results: The results of MeOH extracts showed that the highest amount with 14.85 gr/plant was obtained in the Areshtanab population. The populations had a significant effect on total phenolic concentrations [P < 0.001] and the Areshtanab with 0.281 mg GAE/g DW had higher phenolic levels than other populations. The results of TLC of iridoids showed that 15 populations had about 11 iridoids components. Cluster analysis by using Ward's method detected that the studied populations of E. laciniata were separated into three different groups
Conclusion: In summary, higher values of the total phenols and iridoids in the Areshtanab, Malek-Kian, and Til populations were considered to indicate higher levels of phytochemical heterogeneity and significant diversity between populations, which could be used to domesticate and develop the breeding programs

RESUMO
The aim of this review was to represent a category of applied plant biostimulants and to highlight the effect of their application on morphological and phytochemical properties of medicinal plants in in vivo and in vitro conditions and their mechanism of action. Plant biostimulants, safe for both human beings and the environment, are substances or materials, except for nutrients and pesticides, which have the ability to beneficially modify plant growth and have been accepted over the past decade. Plant biostimulants have natural and synthetic origin. The natural biostimulants contain amino acids, bacteria, seaweed, yeast, chitosan, phytohormones, and also plant growth regulators [synthetic hormones], phenolic compounds, inorganic salts, essential elements, and other different substances are some examples of synthetic biostimulants. The plant biostimulants through different mechanisms of action [such as nitrogen assimilation] are sustainable management practice for production of medicinal plants, increasing biomass production, and enhancing secondary metabolites synthesis and it is investigated and shown in many studies in recent years. Furthermore, there are many reports on positive effects of biostimulants and elicitors application on medicinal plants in in vitro culture condition. Some products of companies active in the formulation of biostimulants in Iran are mentioned in this review. In conclusion, yield response in medicinal plants to biostimulants application showed that each medicinal plant responds in a different way based on the chemical composition and components of biostimulants, the timing and rate of application

RESUMO
Polyploidy is one of the widespread phenomena in plant kingdom, which has a vital role in evolution and speciation of plants and is usually accompanied by significant changes in morphology, cell and organ size, expression patterns of genes, respiration and phtotosynthesis, regeneration ability, fertility, biochemistry and metabolom of plants. Therefore polyploidy, especially tetraploidy, has been widely applied in modification of various characteristics of plants. The diversity of traits resulted by the induction of polyploidy, depends on the genotype and species and therefore is not always useful. Though tetraploidy usually results in fewer seeds and decrease of fertility but in cases where the increase in biomass or concentration of medicinal compounds is of importance, it can be efficiently applied for breeding of medicinal plants. Autotetraploidy doubles the gene dosage and allotetraploidy collects the useful allels of a biosynthetis pathway in a resulted hybrid and therefore may improve the production of secondary metabolites. According to the importance of herbal medicine and increasing demand for medicinally important secondary metabolites in our country, we describe the effects of polyploidy on various characteristics of medicinal plants and the methods of induction and selection of polyploid plants in this
