The leaves of "Justicia adhatoda" contains phytochemicals such as alkaloids, tannins, saponins, phenolics and flavonoids. Phenolics, sometimes called "phenols", consist of an aromatic 6-carbon ring bonded to a hydroxy group. The ABTS radical cation is reactive towards most antioxidants including phenolics, thiols and Vitamin C. All these except caffeic acid are members of the flavonoid category of phenolics. One of the common secondary compounds used by "Pinaceae" are phenolics or polyphenols. Thermosets are subdivided into several resin systems including epoxies, phenolics, polyurethanes, and polyimides. Some examples of phenolics used for defense in plants are&colon; lignin, silymarin and cannabinoids. Phenolics are active ingredients in some household disinfectants. Phosphomolybdic acid is used as a reagent for staining phenolics in thin layer chromatography. Use of ferric chloride (FeCl) tests for phenolics in general. Vitamin C and phenolics are present in red raspberries. Similar to cherries, strawberries, and raspberries, almonds are also rich in phenolics. This is possible due to the action of lichen phenolics such as usnic acid derivatives. Resveratrol is a flavinoid belonging to the phenolics family. Other more detailed chemical research has elucidated the difficulty of isolating individual phenolics.
