Telfairia occidenlalis possesses high antioxidant activity. However, the antioxidant components of the plant have not yet been identified. This study was undertaken to identify the phenolies in the leaf of the plant. Extract and fractions of the leaf of the plant were analyzed using the HPLC and GCMS. HPLC anal. revealed the presence of gallic acid (22.19μg/mg), catechin (29.17μ/mg), caffeic acid (9.17μg/mg), ferulic acid (0.94μg/mg), sinapic acid (1.91μg/mg) and 4-hydroxy benzoic acid (43.86μg/mg) in the aqueous extract Phenolics fraction contained gallic acid (0.88μ/mg), catechin (2.70μ/mg), caffeic acid (7.92μg/mg), ferulic acid (2.72μg/mg), benzoic acid (6.36μg/mg), p-coumaric acid (1.48μg/mg), quercetin (12.00μg/mg). Only caffeic acid (2.50μg/mg), ferulic acid (0.44μg/mg) and quercetin (8.50μg/mg) were detected in the flavonoid fraction. While GCMS anal. showed the presence of methylparaben; ethylparaben; benzoic acid; 4-hydroxy-2-methoxy-3,5,6-trimethyl-, Me ester; 4-hydroxy-3-methoxy; phenol, 5-methoxy-2-(methoxymethyl)-; phenol, 5-methoxy-2, 3-dimethyl; and phenol, 2-(2-benzothiazolyl)-. This study is the first to reveal the identity of some phenolics components of the leaf of Telfairia occidentalis. In the experiment, the researchers used many compounds, for example, Dimethyl decanedioate (cas: 106-79-6Application In Synthesis of Dimethyl decanedioate).
Dimethyl decanedioate (cas: 106-79-6) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Application In Synthesis of Dimethyl decanedioate
