Abstract:
Citric acid-catalyzed ultrasonic extraction is one of the emerging methods of extracting bioactive compounds in plants including Morinda citrifolia leaves. The ultrasonic extraction method offers a shorter operating time, reduces solvent consumption, and is environmentally friendly. This study was conducted to determine the effect of processing parameters citric acid concentration (0.1% w/v, 0.55% w/v, and 1.0% w/v), extraction time (1 min, 6 mins, and 11 mins), and power of extraction (1%, 38%, 75%) which affects the citric acid-catalyzed ultrasonic extraction and to study the effectiveness o

Abstract Currently, the process of releasing patchouli oil is carried out by extraction, water-steam distillation, and hydrodistillation. A new method for extracting patchouli by hydro distillation using electric voltage by ohmic heating has not been widely used. This paper aims to determine the energy requirements for extraction using ohmic heating. The method used is to make an extraction tool using electricity and extract the dried patchouli leaves. The electricity used for extraction is AC electricity with voltages of 90 V, 100 V, and 110 V. The ratio of patchouli to water is 1:12. Observa

The extracts have been analyzed qualitatively and quantitatively to valuate yield and selectivity of extractions of ginsenosides. Water supplied the lowest yield. The yields of extracts with liquid ammonia were higher than those with m ethanol-water (60%). Yields of the ginsenosides Rb1, Rb2, Rc and Rd by extracting with liquid ammonia are about twice as much as those of the extraction with methanol-water (60%).

The ethanol concentration, solid-to-solvent ratio, extraction temperature and extraction time were optimized by using orthogonal array design, an ultrasonic-assisted extraction (UAE) method was formed for extracting total flavonoids from Cassia Seeds. The optimal conditions for total flavonoids preparation were found to be extracted at 55 °C for 40 min with 75% (v/v) ethanol and a solid-to-liquid ratio of 1:30 (g/mL). The UAE was proven more efficient than the conventional extraction (CE) technique, which could be considered a time-saving method. Therefore, the UAE could be a promising candida

Abstract:
Fabric phase sorptive extraction (FPSE) is a new-generation of sample preparation technique that effectively combines representative characteristics of solid-phase microextraction – SPME (equilibrium-based extraction) and solid phase extraction – SPE (exhaustive extraction). FPSE was introduced in 2014 by Kabir A. and Furon K.G. FPSE utilizes a fabric substrate (natural or synthetic such as cotton or polyester) that is chemically coated with a hybrid sorbent (organic-inorganic sol-gel). The entire assembly (fabric substrate coated with the sol-gel polymer) results in a fast and sensitive micro

Abstract:
The paper presents the results of studies on the extraction of phenolic compounds from the leaves of trees of the Salicaceae family, namely aspen and willow. A method for extracting phenolic compounds of salicin and quercetin by extraction using ethyl alcohol as a solvent is described. The method of identification of salicin and quercetin by thin-layer chromatography (TLC) is described. Digital processing of the obtained results was carried out using the computer program “Sorbfil Visualizer” (Krasnodar). The optimal operating parameters of the process, allowing to obtain the highest yield of t

Abstract:
Genetic analysis and mapping in grapes has been difficult because of the long generation period and paucity of genetic markers. In the present work, chromosome linkage maps were developed with RAPD, RFLP and isozyme loci in interspecific hybrid cultivars, and RAPD markers were produced in a V. vinifera population. In three cultivars, there were 19 linkage groups as expected for a species with 38 somatic chromosomes. These maps were used to locate chromosome regions with linkages to important genes, including those influencing powdery mildew and botrytis bunch rot resistance; flower sex; and be

Abstract:
La transición energética, orientada a la descarbonización, debe venir acompañada de la transición de las instituciones políticas, diferenciando entre los Estados productores de petróleo y de minerales estratégicos. Estas instituciones políticas pueden clasificarse en cinco grupos: (i) la propiedad pública sobre los yacimientos, (ii) los mecanismos de captura del ingreso extractivo por el Estado por medio de regalías y otros títulos contractuales; (iii) los mecanismos de captura del ingreso extractivo por el Estado por medio de tributos; (iv) la ordenación y supervisión de los operadores a carg
