Investigation and dynamic changes of phenolic compounds

Research has found that using ylang-ylang in aromatherapy may help improve anxiety, depression, and high blood pressure. L. Picariello, A. Rinaldi, F. Martino, F. Petracca, L. Moio, and A.

This condensation leads to the formation of cis- and trans-5-hydroxy-2-methyl-1,3-dioxane as well as cis- and trans-4-hydroxymethyl-2-methyl-1,3-dioxalane. The smell of these substances is sensed as sweet and is characteristic for Port wine [ 13]. Shah G, Shri R, Panchal V, Sharma N, Singh B, Mann AS.

Aromatherapy Car Blends Compatibility The transformations of anthocyanins and tannins lead to colour changes of red wines: from reddish, characteristic of young red wine, to mauve or red-brown characteristic for mature wine [ 66]. According to [ 67], dye polymerization reactions do not depend on oxygen and are initiated due to elevated temperature. On the other hand, other studies [ 45, 51] showed the effect of oxygen on these phenomena by the following mechanisms: This systematic review investigated the clinical effects of inhalation aromatherapy for the treatment of sleep problems such as insomnia. Studies on sleep problems and inhalation aromatherapy, published in Korean and international journals, were included in the meta-analysis Direct condensation reaction between tannins (nucleophilic C6 or C8 carbons of (+)-catechin, (-)-epicatechin, or procyanidins) and the electrophilic C4 carbon of anthocyanin. The colourless condensation products are oxidized to flavylium ion with an intense red colour [ 53, 54] (2) As a result of the addition reaction, in the acidic environment, the proton is added to the ethanal. The resulting electrophilic carbocation reacts with the C6 or C8 carbons of the flavanol and then, after dehydration, with the C8 carbon of anthocyanin (present in a colourless form). The compound formed as a result of these reactions may then be protonated to form coloured condensation products of anthocyanins and flavan-3-oles connected by an ethyl bridge. According to this mechanism, malvidin 3-glucoside reacts with various procyanidins [ 1]. Acetaldehyde can also mediate the condensation of anthocyanins leading to formation of oligomeric methylmethine-linked anthocyanins. These compounds are not stable and can undergo further reactions with malvidin 3-glucoside or carboxypyrano-malvidin-3-glucoside forming orange or blue pigments, respectively [ 9] (3) Because of the reaction between the vinylphenol molecule and the C4 and C5 carbons of anthocyanin, followed by the oxidation of the resulting compound, a pyran ring is formed. The reaction between the flavylium ion and the catechin molecule with a vinyl group at the C8 carbon produces pigments with a red-orange colour (pyranoantocyanins) and other compounds that are resistant to pH changes and decolourization by the SO 2 [ 5]. The indirect products of polymerization reaction are ethylidene and vinyl-linked anthocyanins and flavanols and vinyl-pyranoanthocyanins [ 51]It causes oxidation of phenolic compounds to the corresponding quinones, which are then polymerized, resulting in yellow-brown pigments. This reaction involves the iron and copper atoms that catalyze oxidation reactions. The main compounds associated with the browning of white wine are not only (+)-catechin, (-)-epicatechin, and dimers of proanthocyanidins B1-B4 but also coumarin and stearic, ferulic, and coffee acids, if they react with the mentioned compounds (2) It oxidizes tartaric acid to the glyoxylic acid forming bridges between the phenolic compounds, leading to their condensation, and copper and iron atoms are the catalysts. The colourless adducts of the two molecules of (+)-catechin connected through the carboxymethine bridge as a result of dehydration are transformed into yellow-brown xanthylium salts (3) It oxidizes phenolic compounds, resulting in hydrogen peroxide generation, which in turn oxidizes ethanol to acetaldehyde. Acetaldehyde forms bridges between (+)-catechin molecules (giving dimers joined by ethyl bridge) and also between dimers resulting from the oxidation of tartaric acid. This leads to the formation of brown pigments, the intensity of which is proportional to the degree of polymerization Oxygenation of must increases the concentration of esters such as acetates (propyl, isobutyl, isoamyl, 2-phenylethyl, and ethyl) and ethyl esters (ethyl propanoate, ethyl isobutanoate, ethyl butanoate, ethyl hexanoate, ethyl octanoate, ethyl decanoate, ethyl laurate, ethyl palmitate, ethyl pyruvate, and ethyl lactate) as well as butyl lactate and hexyl lactate. The amount of higher alcohols (propanol, isobutanol, isoamyl alcohols, phenylethyl alcohol, butanol, hexanol, heptanol, octanol, and decanol) also rises. An increase in the concentration of esters while maintaining a relatively low concentration of higher alcohols may lead to the intensification of the fruity aroma [ 34]. With regard to volatile compounds, [ 35] obtained different results. They showed that the content of volatile compounds significantly depends on the yeast strain, and under partial oxygenation of the must, lower concentrations of most esters and acids were obtained, while higher amounts of alcohols were observed [ 35]. Phenolic compounds in intact fruits are mostly found in vacuoles, but as a result of their damage (at the stage of harvesting and subsequent stages of fruit processing), these compounds are released. Consequently, enzymes belonging to the oxidoreductase class may cause oxidation of these compounds (in particular hydroxybenzoic and hydroxycinnamic acid esters, such as coumaric acid and caftaric acid) [[ 3]; Morales et al., 2015].
