Nowadays, most of the flavor compounds Fig. 1. Structure of trans-anethole (A) on the world market are produced by chemical synthesis or by direct extraction from plants (Bicas et al., 2010). However, chemical synthesis results the toxicity of organic substrates and products, and the frequently in environmentally unfriendly production culture medium (Bertrand et al., 2013; Baeza-Jimenez´ processes and the undesirable formation of by- et al., 2014; Leon´ et al., 1998). products, thereby reducing process efficiency and In this sense, microbial transformation of propenylbenzenes has attracted considerable attention increasing downstream cost (Longo and Sanroman,´ 2006; Wohlgemuth, 2010). Besides, natural flavor becoming one of the most important topics (Hua production by extraction from plants has some et al., 2007; Overhage et al., 2006; Yamada et al., 2007a, 2007b; Zhang et al., 2006). Propenylbenzenes, problems. First, the concentration of the desired compound is commonly low, making the extraction, extracted from plant essential oils, are common isolation and formulation very expensive (Xu et al., aromatic compounds often employed as starting intermediates for the production of various flavors 2007). Second, the level of flavor compounds in plants is influenced by different factors including and fragrances. These compounds can be transformed weather, agronomic conditions, subspecies genotype, by whole microorganisms or some enzymes to give plant age and diseases (LongoFigure and Sanrom 2.

    catalysts Review Catalytic Transfer Hydrogenolysis Reactions for Lignin Valorization to Fuels and Chemicals Antigoni Margellou 1 and Konstantinos S. Triantafyllidis 1,2,* 1 Department of Chemistry, Aristotle University of Thessaloniki, 54124 Thessaloniki, Greece; [email protected] 2 Chemical Process and Energy Resources Institute, Centre for Research and Technology Hellas, 57001 Thessaloniki, Greece * Correspondence: [email protected] Received: 31 October 2018; Accepted: 10 December 2018; Published: 4 January 2019 Abstract: Lignocellulosic biomass is an abundant renewable source of chemicals and fuels. Lignin, one of biomass main structural components being widely available as by-product in the pulp and paper industry and in the process of second generation bioethanol, can provide phenolic and aromatic compounds that can be utilized for the manufacture of a wide variety of polymers, fuels, and other high added value products. The effective depolymerisation of lignin into its primary building blocks remains a challenge with regard to conversion degree and monomers selectivity and stability. This review article focuses on the state of the art in the liquid phase reductive depolymerisation of lignin under relatively mild conditions via catalytic hydrogenolysis/hydrogenation reactions, discussing the effect of lignin type/origin, hydrogen donor solvents, and related transfer hydrogenation or reforming pathways, catalysts, and reaction conditions. Keywords: lignin; catalytic transfer hydrogenation; hydrogenolysis; liquid phase reductive depolymerization; hydrogen donors; phenolic and aromatic compounds 1. Introduction The projected depletion of fossil fuels and the deterioration of environment by their intensive use has fostered research and development efforts towards utilization of alternative sources of energy. Biomass from non-edible crops and agriculture/forestry wastes or by-products is considered as a promising feedstock for the replacement of petroleum, coal, and natural gas in the production of chemicals and fuels.

ABSTRACT The purpose of this research is to quantify the carcinogenic compound safrole in the traditional preparation method of making sassafras tea from the root of Sassafras albidum. The traditional method investigated was typical of preparation by members of the Eastern Band of Cherokee Indians and other Appalachian peoples. Sassafras is a tree common to the eastern coast of the United States, especially in the mountainous regions. Historically and continuing until today, roots of the tree are used to prepare fragrant teas and syrups.

Currently, the etiology of these pathological features is not clearly understood and, therefore, no curative treatment is available. Since the 1990s, hydrogen sulfide (H2S) has been described as the third gasotransmitter with plethoric regulatory functions in cardiovascular tissues, especially in pulmonary circulation. Alteration in H2S biogenesis has been associated with the hallmarks of PH. H2S is also involved in pulmonary vascular cell homeostasis via the regulation of hypoxia response and mitochondrial bioenergetics, which are critical phenomena affected during the development of PH. In addition, H2S modulates + ATP-sensitive K channel (KATP) activity, and is associated with PA relaxation. In vitro or in vivo H2S supplementation exerts antioxidative and anti-inflammatory properties, and reduces PA remodeling. Altogether, current findings suggest that H2S promotes protective effects against PH, and could be a relevant target for a new therapeutic strategy, using attractive H2S-releasing molecules.
