AB  - This study has explored the effect of three phytohormones application, based on α-naphthyl acetic acid, named INCIT 1, INCIT 8 and INCIT K, on the root system growing potential and rooting stimulation of Thymus pannonicus All. cuttings. This plant is highly reputable not only in a folk medicine, but also recognized in the business sector, due to a multiple uses and beneficial effects on human health.
The research was located in Veliko Središte, Vršac (Serbia) and conducted in May, 2021. The cuttings were dipped in a powdered formulation of phytohormones and placed in plastic containers pre-filled with commercial substrate. The phytohormone-free variant was taken as a control. After 2 months, the cuttings were removed and the morphological and biological properties (polyphenols content and antioxidant activity by DPPH radical and FRAP method) were measured.
Based on the morphological results, all of treated samples showed satisfactory behaviour, whereby the most suitable phytohormone to stimulate the growth of cuttings was INCIT 8, in which the average weight of the aboveground vegetative part of the plant and root mass were higher for more than 60% in relation to the control; the number of roots were about 25% higher, whereby the mass of the whole plant was almost 3 times increased. Considering the biological activities in a 5% aqueous infusions of the samples, it was found that the polyphenols content and the antioxidant activity were lowered in treated samples, with relation to the control, excluding the sample INCIT 8 where the FRAP value was slightly increased, while the inhibition of DPPH radicals was higher by around 15%.
The applied phytohormone treatment may ensure economically viable yields of standard or even improved plant quality. In the following period, it is expected that all of treated adult plants will have a higher content of biologically active substances.

AB  - The objective of this work was to study the relation between the manufacturing conditions of microcrystalline cellulose (MCC), its physicochemical properties and its tableting behavior. Two different preparation procedures were used to produce MCC from wheat straw, utilizing an acid hydrolysis method, either using only sulfuric acid or combination of sulfuric and hydrochloric acid. The tableting behavior of obtained MCC samples and mixtures of MCC with ibuprofen was studied using a dynamic powder compaction analyzer. It was observed that some of the obtained MCC samples showed better flowing properties than commercially available Vivapur® PH101 and also very high values of tensile strength, solid fraction and elastic recovery. This can be linked with its good compaction behavior, but on the other hand it can cause problems with the disintegration of the tablets. In mixtures with ibuprofen, MCC samples showed lower values of tensile strength, while on the other hand elastic recovery did not seem to be much affected, still exhibiting very high values. According to the obtained results, it can be concluded that MCC obtained from the agricultural waste could have satisfactory properties for tablet preparation by the direct compression method. Further studies are needed to optimize process conditions in order to achieve better physicochemical characteristics, especially in terms of elastic recovery.
