What are total phenolics?
Phenolic compounds are important plant constituents with redox properties responsible for antioxidant activity [22]. The hydroxyl groups in plant extracts are responsible for facilitating free radical scavenging.
What is the meaning of phenolic?
phenolic. noun. Definition of phenolic (Entry 2 of 2) 1 : a usually thermosetting resin or plastic made by condensation of a phenol with an aldehyde and used especially for molding and insulating and in coatings and adhesives. — called also phenolic resin.
What is TPC and TFC?
Abstract. The aim of present work was to assess the total phenolic content (TPC), total flavonoid content (TFC), phenolic compounds and antioxidant properties of various extracts of three Ceropegia spp.: Ceropegia spiralis, Ceropegia panchganiensis and Ceropegia evansii from Western Ghats of India.
What is total phenolic content assay?
Total phenolic content (TPC) assay using Folin-Ciocalteu method was used to assess the presence and level of phenolic compounds in each sample. The present study showed that both methanolic and ethanolic extracts of P. minus had the highest TPC and followed by M. minus extracts as compared to the other samples.
What are phenolics used for?
Phenols are widely used in household products and as intermediates for industrial synthesis. For example, phenol itself is used (in low concentrations) as a disinfectant in household cleaners and in mouthwash. Phenol may have been the first surgical antiseptic.
What are flavonoids and phenolics?
Phenolics are the largest group of phytochemicals that account for most of the antioxidant activity in plants or plant products[3]. Flavonoids are the largest group of naturally occurring phenolic compounds, which occurs in different plant parts both in free state and as glycosides.
Which of following is phenolic?
Picric acid is phenolic while others are non-phenolic.
What are examples of phenols?
Phenols are common in nature; examples include tyrosine, one of the standard amino acids found in most proteins; epinephrine (adrenaline), a stimulant hormone produced by the adrenal medulla; serotonin, a neurotransmitter in the brain; and urushiol, an irritant secreted by poison ivy to prevent animals from eating its …
Why do we calculate total phenolic content?
Phenolic compounds have redox properties, which allow them to act as antioxidants [20]. As their free radical scavenging ability is facilitated by their hydroxyl groups, the total phenolic concentration could be used as a basis for rapid screening of antioxidant activity.
How are phenolics classified?
Phenols that contain a carboxylic acid are termed as phenolic acids. If the carboxylic acid functional group is directly bonded to the phenol ring, the phenolic compound is termed as hydroxybenzoic acid.
What is the meaning of the word phenolic?
Definition of phenolic. (Entry 1 of 2) 1a : of, relating to, or having the characteristics of a phenol. b : containing or derived from a phenol. 2 : of, relating to, or being a phenolic. phenolic.
What is phenolic resin used for?
1 : a usually thermosetting resin or plastic made by condensation of a phenol with an aldehyde and used especially for molding and insulating and in coatings and adhesives. — called also phenolic resin. 2 : phenol sense 2.
What is the simplest of the class of phenols?
The simplest of the class is phenol, C 6H 5OH. Phenolic compounds are classified as simple phenols or polyphenols based on the number of phenol units in the molecule.
What is phenol used for in medicine?
Phenol is also used in drugs such as Chloraseptic to treat pharyngitis as an oral analgesic or anesthetic. Phenol and its related compounds are also used in the diagnosis of surgical ingrown toenail, a procedure called phenolization.
