“…It is well-recognized that different solvents have the ability to extract different types of phytochemicals on the basis of their polarity; henceforth, the biological activity of the extracts can be varied [22][23][24]. Alcohol extracts are more preferable over water extracts in many pharmacological assays, since lipophilic bioactive secondary metabolites; usually phenolics are more easily extracted with alcohol than with water [25].…”

Objective: This study was performed to identify the phytochemicals and comparatively evaluate the antioxidant activity of Calotropis procera and Azadirachta indica by detection of total phenolics, hydrogen peroxide radical scavenging activity, and estimation of condensed tannins in different solvent systems and at different temperatures.Methods: Leaves of C. procera and A. indica were extracted in water, methanol by soaking dried leaf powder at room temperature and also by boiling the leaf powder in water for 30 minutes. Phytochemical tests were performed in all of the extracts. The antioxidant activity was determined by hydrogen peroxide radical scavenging activity. Quantitative estimation of total phenolics and hydrolysable tannins was also performed. Results:The total phenolics in both leaf extracts was obtained maximum in boiled extract (40.7±1.20 mg gallic acid equivalent [GAE]/g dry extract in C. procera and 33.66±1.45 mg GAE/g dry extract in A. indica). The amount of hydrolysable tannins in both leaf extracts was found to be highest in methanol (150±1.88 mg catechin equivalent/g dry extract in C. procera and 144.8±2.63 mg catechin equivalent/g dry extract in A. indica). Conclusion:The study showed promising results indicating that these plants are a good source of antioxidants. The majority of phytochemicals were extracted in distilled water and methanol acts as a good solvent for extraction of tannins, whereas an increase in temperature leads to poor extraction of tannins.

“…Different solvents yield different natural compounds from the material taken and also the extract composition differs from solvent to solvent. Therefore, selection of a solvent for oil extraction is a most critical step for Soxhlet extraction [39]. Hexane, an extensively used solvent for oil extraction has peculiar characters such as excellent oil miscibility, distinguishable boiling point range (63-69°C) and easily recoverable.…”

Abstract:The ever growing demand for the energy fuels, economy of oil, depletion of energy resources and environmental protection are the inevitable challenges required to be solved meticulously in future decades in order to sustain the life of humans and other creatures. Switching to alternate fuels that are renewable, biodegradable, economically and environmentally friendly can quench the minimum thirst of fuel demands, in addition to mitigation of climate changes. At this moment, production of biofuels has got prominence. The term biofuels broadly refer to the fuels derived from living matter either animals or plants. Among the competent biofuels, biodiesel is one of the promising alternates for diesel engines. Biodiesel is renewable, environmentally friendly, safe to use with wide applications and biodegradable. Due to which, it has become a major focus of intensive global research and development of alternate energy. The present review has been focused specifically on biodiesel. Concerning to the biodiesel production, the major steps includes lipid extraction followed by esterification/transesterification. For the extraction of lipids, several extraction techniques have been put forward irrespective of the generations and feed stocks used. This review provides theoretical background on the two major extraction methods, mechanical and chemical extraction methods. The practical issues of each extraction method such as efficiency of extraction, extraction time, oil sources and its pros and cons are discussed. It is conceived that congregating information on oil extraction methods may helpful in further research advancements to ease biofuel production.

“…Resorcinolic lipids and their derivatives have drawn the interest of researchers, given their range of biological properties, which allows these compounds to be used as antibiotic, antifungal, molluscicidal, antitumoral, antiparasitic, and antioxidant agents. 1,2 In 2000, Brady et al 3 isolated five non-isoprenoid octaketide phenolic lipids from the endophytic fungi Cytospora sp. and Diaporthe sp., which were named cytosporones A-E (1-5, Figure 1).…”

A busca por herbicidas eficientes e ambientalmente corretos tem sido foco de numerosos estudos sobre a síntese de compostos isolados de fontes naturais. Citosporonas, as quais são lipídeos fenólicos isolados de fungos, apresentam notáveis propriedades biológicas. Este artigo relata a preparação das citosporonas A, B e C, através de uma rota sintética curta e com excelentes rendimentos. Os compostos sintetizados foram avaliados quanto às suas atividades alelopáticas em sementes de alface (Lactuca sativa L). Citosporona A e seu precursor metilado mostraram notável atividade alelopática, inibindo a germinação de sementes e crescimento das plântulas.The search for efficient, environmentally friendly herbicides has been the focus of numerous studies on the organic synthesis of compounds isolated from natural sources. Cytosporones, which are phenolic lipids isolated from fungi, exhibit noteworthy biological properties. This paper reports the preparation of cytosporones A-C from the same starting material through a short synthetic route, with good yields. All compounds were tested for allelopathic activity on lettuce (Lactuca sativa L) seeds. Cytosporone A and its methylated precursor showed remarkable allelopathic activity, inhibiting seed germination and plantule growth.
