The article presents the data on seed germination of Salvia officinalis L. in laboratory and field conditions. The mass of 1000 seeds of the plant is 7-8g. It has been revealed that the optimal sowing time for S. officinalis L. is the spring period. At the same time, laboratory and soil germination of freshly harvested seeds of S. officinalis L. constitutes 70-85%. Plant seeds sprout 15-20 days after sowing. Plant safety in the conditions of Tashkent oasis in the aisles is 70-80%. In the first year of life, plants do not enter the generative phase of development. In recent time, a collection of this plant has been created and methods of mass reproduction, as well as agricultural measures, are being studied.

The main objective of this study was to intensify the extraction of total phenols from Salvia officinalis L. using instant controlled pressure drop (DIC) as a texturing pre-treatment. The effect of solvent type on Total Phenolic Content (TPC) was also studied. TPC was determined using spectrophotometric Folin-Ciocalteau method and external calibration with Gallic acid. The obtained results showed that water was the most efficient solvent to extract total phenols from Salvia officinalis L. Moreover, texturing and expansion by DIC pretreatment had a great impact on polyphenol yields and revealed greater extraction kinetics. Likewise, drying kinetics of DIC-treated sage was enhanced compared to the raw material. DIC-assisted extraction can be considered as a promising technology to use in the case of the Moroccan Salvia officinalis L. as an important Mediterranean source of natural phenols.

In this article, it was found that different standards of mineral fertilizers used to accelerate the medicinal salvia cultivation in the soil and climatic conditions of Tashkent region affect the plant seeds yield. The N90P60K40 norm gave good results for the plants rapid growth when fed with different norms of applied mineral fertilizers. In this case, the data on the cultivation technology of seed seedlings of salvia plant are given.

The quantitative analysis of diterpene acids in raw materials of closely related species of genus Salvia was carried out. The objects of present research were Salvia officinalis L., Salvia tesquicola Klokov and Pobed., Salvia nutans L., which grow in neighboring south (Samara and Orenburg) regions. During analysis different raw materials, such as herbs and leaves, were studied. It was determined that total amount of diterpene acids varies from 1,04% to 1,32% in leaves of different species of Salvia and from 1,13% to 1,67% in herbs of different species of Salvia. The raw material of Salvia nutans contains minimal amount of diterpene acids, but in the raw material of Salvia tesquicola the quantitative analysis shows different results, which depend on the region. The medical raw material of Salvia officinalis, which is cultivated in Samara region, includes sufficient amount of diterpene acids.

Summary The study upon sage (Salvia officinalis L.) has been carried out at the Experimental Section of Department of Vegetables and Medicinal Plants, University of Life Sciences in Lublin. The aim of present study was to evaluate the yield and chemical composition of essential oil extracted from sage leaves harvested from a three-year plantation. The sage herb harvest date in the third year of cultivation had a significant impact on the yield of plants. Higher yield of fresh and dry herb, dry leaves, and essential oil was achieved in August (the second harvest time) than in May (the first harvest time). Chromatographic examination indicated the presence of 50 chemical compounds in sage essential oil. It was a variable percentage of essential oil components depending on the raw material harvest time. The main components of the sage essential oil were: 1,8-cineole (16.08-18.04%), α-thujone (10.40-21.51%) and camphor (5.24-18.08%).

Salvia Officinalis L

Inflammatory diseases of the female genital area are dominant among the total number of gynecological diseases. Among all the variety of medicinal plant materials used in official medicine, salvia medicinal draws attention to itself, which has repeatedly proved its effectiveness in the treatment of inflammatory diseases of the mucous membranes of various origins. That is why the goal was set to develop a technology for obtaining a liquid extract from the leaves of Salvia officinalis L. As a result of the study, a method was developed for obtaining a liquid extract by selecting the optimal extraction conditions. It was found that the optimal raw material-extractant ratio is 1:50, the optimal concentration of the extractant ethyl alcohol is 70%, the infusion time of the extract is 24 hours. To intensify the extraction process, the method of ultrasonic processing of raw materials at the soaking stage was used. The optimal time for processing plant materials with ultrasound was 45 minutes. As a result of using this method to obtain a liquid extract from the leaves of sage officinalis, the yield of phenolic compounds was doubled in comparison with obtaining an extract without sonication of raw materials and amounted to 182.7 mg / g of flavonoids in terms of luteolin-7-glycoside.

Abstract Research exists that evaluates the mechanics of swallowing respiratory coordination in healthy children and adults as well and individuals with swallowing impairment. The research program summarized in this article represents a systematic examination of swallowing respiratory coordination across the lifespan as a means of behaviorally investigating mechanisms of cortical modulation. Using time-locked recordings of submental surface electromyography, nasal airflow, and thyroid acoustics, three conditions of swallowing were evaluated in 20 adults in a single session and 10 infants in 10 sessions across the first year of life. The three swallowing conditions were selected to represent a continuum of volitional through nonvolitional swallowing control on the basis of a decreasing level of cortical activation. Our primary finding is that, across the lifespan, brainstem control strongly dictates the duration of swallowing apnea and is heavily involved in organizing the integration of swallowing and respiration, even in very early infancy. However, there is evidence that cortical modulation increases across the first 12 months of life to approximate more adult-like patterns of behavior. This modulation influences primarily conditions of volitional swallowing; sleep and naïve swallows appear to not be easily adapted by cortical regulation. Thus, it is attention, not arousal that engages cortical mechanisms.
