“…At the present time, we may only speculate upon the physiological significance of accumulations of phenolic materials in aleurone cell walls. The occurrence of ferulic acid as a component of wheat flour and other plant tissues is now well established (Ibrahim and Towers 1960;Fausch, Kundig, and Neukom 1963;Levand and Heinicke 1968), but no direct evidence is available which provides for any functional significance. Fausch, Kundig, and Neukom (1963) have suggested that esterification of ferulic acid and other phenolic compounds to cell wall polysaccharides might provide a means of detoxifying these compounds in some plants.…”

In the ungerminated seed, the cell walls of the aleurone layer of wheat (Triticum aestivum cv. Heron) are strongly autofluorescent and are stained by aniline blue, resorcinol blue, toluidine blue, and the periodic acid-Schiff's reaction. Thin-layer chromatography of acid or alkaline extracts and microspectrofluorimetry indicate that the fluorescent component of the wall is ferulic acid. During germina-tion, the ferulic acid disappears from the aleurone cell wall in a specific pattern and its loss is accompanied by loss of stainable substance except in the innermost layer of the wall. These facts suggest that the aleurone cell wall contains a ferulic acid-carbohydrate complex which renders it relatively resistant to the action of the hydro-lases which digest the endosperm.

“…It is covalently linked by ester linkages to polysaccharides and ether or ester bonds to lignin in plant cell walls. In nature, FA is present in various plants such as citrus fruits , wheat , spinach , sugar beet , , cereals , sugar cane bagasse , , neem , pineapple , , and so forth. It has many important applications in the field of medicine such as an antioxidant activity , cholesterol-lowering activity , prevention against thrombosis and atherosclerosis , antimicrobial and anti-inflammatory activity , and anticancer effect .…”

Ferulic acid (FA) is a phenolic antioxidant present in plants, which is widely used in the food and cosmetic industry. In the present study, various agricultural wastes such as maize bran, rice bran, wheat bran, wheat straw, sugar cane baggasse, pineapple peels, orange peels, and pomegranate peels were screened for the presence of esterified FA (EFA). Among the sources screened, maize bran was found to contain the highest amount of EFA. Pineapple peels, orange peels, and pomegranate peels were also found to contain traces of EFA. Alkaline extraction of EFA from maize bran was carried out using 2 M NaOH. Response surface methodology (RSM) was used for optimization of EFA extraction, which resulted in a 1.3-fold increase as compared to the unoptimized conventional extraction technique. FA was analyzed by means of high-performance liquid chromatography (HPLC). Purification was carried out by adsorption chromatography using Amberlite XAD-16 followed by preparative high-performance thin-layer chromatography (HPTLC). The recovery of Amberlite XAD-16 purified FA was up to 57.97% with HPLC purity 50.89%. The fold purity achieved was 1.35. After preparative HPTLC, the maximum HPLC purity obtained was 95.35% along with an increase in fold purity up to 2.53.

“…Reports regarding the presence of ferulic acid, catechin, gallic acid, epicatechin, isomeric N,N′-diferuloylspermidines, hydroxycinnamoyl(di)glycerides, mono-and di-feruloylspermidine, hydroxycinnamic acid amides, hydroxycinnamoylspermidines, and other compounds in PPE are available in the literature. [31][32][33][34][35][36][37][38] To study the coloration of wool using PPE, the color values and color coordinates of the dyed wool were measured and the results are presented in Table I. The color values of the samples dyed using PPE without pre-mordanting were less than that for mordanted samples.…”

“…Pineapple peels are reported to contain ferulic acid, which is known to possess antimicrobial, anti-inflammatory, antioxidant, and UV absorber activities. [31][32][33][34][35] The presence of gallic acid, catechin, and epicatechin, along with ferulic acid, in pineapple peels was reported. 36 The antibacterial activity showed only a marginal increase in the presence of the ferrous mordant.…”

Large quantities of pineapple peel waste are discarded every year that can be used for extraction of useful textile functionalization chemicals. In the present work, pineapple peel extract (PPE) was used for simultaneous dyeing and multifunctional finishing of wool fabric. The PPE was used for dyeing wool fabrics, with and without mordants. The dyed fabrics were characterized and evaluated for color values and fastness properties. The functional properties of the dyed fabrics viz. antibacterial activity, UV protection, and antioxidant activity were evaluated. It was confirmed that wool fabric can be dyed using pineapple peel extract without mordants; however, additional color strength can be gained using pre-mordanting. The dyed fabrics showed light shades with good fastness properties along with excellent functional properties.
