The paper studies the morphology, conductivity and electrochemical properties ofcarbon materials, obtained from raw plant materials at different condition of hydrothermalcarbonization, using low-temperature porometry, impedance spectroscopy and galvanostaticcharge/discharge. It is set, that in porous structure of carbon materials micropores are dominant;when carbonization temperature increased the specific surface and pore volume decrease morethan 10 times. The temperature growth results in increasing the electrical conductivity of thecarbon material more than 6 orders. It is found, that the maximal value of specific capacity(1138 mА·h/g) has an electrochemical system based on porous carbon carbonized at 1023 K

Raw Plant Materials

Environmental monitoring and assessment of the prospects for extracting biologically active substances (BAS) from various types of plant biomass requires the development of simple and fast methods for measuring their content in raw materials. A new approach for measuring the content of various flavonoids groups in plant raw material using 1H NMR spectroscopy has been developed, which allows to characterize its resource capabilities and study the effects on their composition different environmental factors without complex sample preparation and standard samples.

Camptotheca acuminata plantations were established in southern Louisiana in an effort to provide raw plant materials for deriving camptothecins, compounds having antitumor activity. This study was conducted to evaluate the growth and camptothecin distribution within the trees. It was found that all plant parts contained camptothecins following 1 year of growth in the field. Branches, roots, and stems accumulated significantly higher concentrations of camptothecins than leaves. Bark was significantly higher in camptothecin concentration than wood. Younger and older tissues within a growing season were not significantly different in camptothecin concentrations. High correlation in camptothecin concentration was found between branch and stem, root and stem, and root and branch, whereas little correlation was observed between bark and wood, and leaf and any other plant component. Field-grown C. acuminata has the observed characteristic of multiple current-year branching. The proportion of bark in term of dry weight and dimension decreased as trees increased in diameter. Dried shoots (bulk) contained 0.042% camptothecin, and dried roots (bulk) contained 0.051% camptothecin. Keywords: Camptotheca acuminata, medicinal plants cultivation, camptothecin content, camptothecin distribution, biomass.

The aim of the research was to study the variability of the content of polysaccharides and flavonoids of Bidens cernua herb, depending on the terms of harvesting, drying conditions and place of growth on the territory of the Republic of Belarus. It was shown that the maximum polysaccharide content was observed in the phase of budding and mass flowering of the plant. Unlike polysaccharides, the content of flavonoids in the budding phase was significantly lower than in the mass flowering phase (p<0.05), which accounts for the maximum content of flavonoids, and in particular, luteolin-7-O-glucoside. The highest polysaccharide content was noted for raw plant materials undergone natural drying or at 40 and 60 °C without ventilation. An increase in the drying temperature or the use of ventilation during drying led to a significant decrease in the content of this group of biologically active substances. The content of flavonoids of Bidens cernua herb, dried at elevated temperature with ventilation, regardless of the drying temperature used, was higher than the content of this group of biologically active substances in comparison with samples of raw plant materials subjected to natural drying (p<0.05). A higher flavonoid content was also noted for Bidens cernua herb, dried without ventilation at 40 and 60 °C. The content of polysaccharides and flavonoids of Bidens cernua herb, depending on the harvesting region, varied between 35.64–90.52 mg/g and 23.11–49.86 mg/g, respectively, and was most dependent on the amount of precipitation per year region. Based on the results obtained, it is recommended to harvest Bidens cernua herb during mass flowering and to dry at 40 °C without ventilation.

Hptlc Method

Introduction- HPTLC uses include phytochemical and biochemical analyzes, ayurvedic medicine quantification and quantification of active ingredients, formational fingerprinting and adulterant testing of formulations. HPTLC can be used as a simple tool for tracking the consistency of plant-based raw plant materials and formulations. The source of many biomarkers is Sammoha Loha Vati. The HPTLC method has been used to classify and measure the bark of leaves and branches. Aim & Objective- Identification and authentication of raw drugs used for Sammoha Loha Vati through HPTLC. Observations- 1. Stationary phase, 2. Mobile phase, 3. Optimization, 4. Preparation of Sample and its use, 5. Separation, 6. Detection. Conclusion and Finding- The use of HPTLC for the screening of pharmaceutical compounds for antimicrobial activities is emerging. Requirements for the testing of new incoming products and their integration into regulatory frameworks are of great significance for the future of HPTLC.

Nutritional Strategies

AbstractIn the current post-antibiotic era, botanicals represent one of the most employed nutritional strategies to sustain antibiotic-free and no-antibiotic-ever production. Botanicals can be classified either as plant extracts, meaning the direct products derived by extraction from the raw plant materials (essential oils (EO) and oleoresins (OR)), or as nature-identical compounds (NIC), such as the chemically synthesised counterparts of the pure bioactive compounds of EO/OR. In the literature, differences between the use of EO/OR or NIC are often unclear, so it is difficult to attribute certain effects to specific bioactive compounds. The aim of the present review was to provide an overview of the effects exerted by botanicals on the health status and growth performance of poultry and pigs, focusing attention on those studies where only NIC were employed or those where the composition of the EO/OR was defined. In particular, phenolic compounds (apigenin, quercetin, curcumin and resveratrol), organosulfur compounds (allicin), terpenes (eugenol, thymol, carvacrol, capsaicin and artemisinin) and aldehydes (cinnamaldehyde and vanillin) were considered. These molecules have different properties such as antimicrobial (including antibacterial, antifungal, antiviral and antiprotozoal), anti-inflammatory, antioxidant, immunomodulatory, as well as the improvement of intestinal morphology and integrity of the intestinal mucosa. The use of NIC allows us to properly combine pure compounds, according to the target to achieve. Thus, they represent a promising non-antibiotic tool to allow better intestinal health and a general health status, thereby leading to improved growth performance.

Plastic is a material that is used to a great extent. Nowadays Petroleum based plastics are widely used for the commercial purpose. This kind of plastics can take more than a century to degrade. Man made plastics have Polyurethane and Polyethylene polymers. It cannot be easily degraded by micro organisms as it don’t recognize as food. When burned plastics release cancer causing carcinogenic chemicals that are harmful to people and the environment. One eco friendly alternative the current commercial plastic is “Bio plastics”. Bio plastics are biodegradable plastics that have components derived directly from renewable raw plant materials. Seven type of bioplastics were made using various combinations of renewable raw materials and plasticizers. In this project, Cassava starch is used as a main biopolymer for the production of bio degradable bags.
