“…Such quality can be ascribed to a relatively high content of total phenolics in the tissues of F. vallesiaca and of phenolic acids in the tissues of C. gryllus. Ferulic and p-coumaric acids are the main phenolic acids present in the cell wall of monocotyledons and especially of Gramineae, as reported by Hartley et al (1990). Theodoru et al (1987) showed that cell walls of barley stems contain p-coumaric (6.79 mg/g), ferulic (3.38 mg/g) and p-hydroxybenzoic acid (0.10 mg/g).…”

 Chrysopogon gryllus and Festuca vallesiaca are components of a number of meadow-pasture communities in Serbia. We performed the analyses of phenolics that influence quality and digestibility of grasses to a great extent. Total phenolics were measured spectrophotometrically and phenolic acids by HPLC analysis. The aboveground parts of C. gryllus contained 10.6 mg/g whereas F. vallesiaca of 21.6 mg/g total phenolics. Bound phenolics dominated over free ones in both species. The content of both free and bound p-coumaric, ferulic, p-hydroxybenzoic and syringic acid was higher in C. gryllus (6.34 mg/g) than in F. vallesiaca (3.96 mg/g). Derivatives of cinnamic acid prevailed in both species compared to the benzoic acid derivatives. Low quality of C. gryllus is connected with its high tissue phenolic acids and mediocre quality of F. vallesiaca with the high content of total phenolics that act unfavourably on digestibility of such grasses.

“…This allows phenolic acids to form cross-links with cell wall macromolecules. [25,26] Hence in the present study, we isolated free (ASFP) and bound (ASBP) phenolic fractions from A. serpyllifolia. The total phenolic content in ASFP and ASBP fractions was found to be 15.1 ± 0.2 mg GAE/g and 0.6 ± 0.09 mg GAE/g respectively.…”

Background: Andrographis serpyllifolia, used as a medicinal plant in traditional practices in India, where in cancer patients are treated using the leaves of A. serpyllifolia. The crude extracts of A. serpyllifolia not only contain a wide variety of phenolic compounds but also show an excellent antioxidant activity. Therefore, this plant might be a good candidate for further development for its antioxidant remedies. However, the biological activities of the phenolic extracts of A. serpyllifolia on cancer have not been studied to date. Objective: To investigate the antioxidant and antiproliferative properties of the phenolics of A. serpyllifolia. Materials and methods: Free and (ASFP) and bound (ASBP) phenolics of A. serpyllifolia were isolated and determined antioxidant and antiproliferative abilities that are required for anticancer properties. Results: Individual phenolic constituents present in each of these fractions and their precise contribution to both antioxidant and antiproliferative activities were determined to justify the traditionally observed result of anticancer properties. Treatment of HeLa cells with ASFP and ASBP showed antiproliferative activity with increased malondialdehyde (MDA) as well as decreased levels of reduced glutathione (GSH). The present experimental data suggest that components within the ASFP may have inherent properties that suppress cancer cell proliferation. The phenolic fractions were also screened for their potential antioxidant activities using DPPH, reducing power, DNA protection, inhibition of lipid peroxidation and protein carbonyls model systems. ASFP exhibited highest antioxidant activity in all the model systems employed to study antioxidant activity. The positive correlation between polyphenolic content of A. serpyllifolia to its antioxidant activity was seen. Conclusion: Potent antiproliferative and DNA protective activity of ASFP and ASBP may contribute significantly against cancer pathogenesis. INTRODUCTIONAndrographis serpyllifolia, an edible, railing and rooting herb known for its traditional medicinal properties. The herb belongs to the family Acanthaceae is widely distributed throughout Deccan and carnatic region of south India [1] and China. Although the related species A. paniculata is well characterized, only a very few studies report the presence of serpyllin, apigen, 7,4'-dimethyl ether and tectochrysin compounds [2,3] and, their implications on bioactivity is not clearly understood. Andrographolide (AG) has been reported as one of the potential active component and believed to be responsible for various bioactivities. [4][5][6] We reported for the first time, the antimetastatic property of pectic polysaccharide [7] and antioxidant activities of crude extracts of A. serpyllifolia. Excessive generation of free radicals is implicated in an ever growing number of disease conditions, including cancer, atherosclerosis, and neurodegenerative diseases. [9,10]

“…This research has focused on factors such as core lignin composition and concentration, lignin-carbohydrate and phenoliccarbohydrate complexes, lignin encrustation, hemicellulose encrustation and cellulose crystallinity (Van Soest 1975;Gordon et al 1977;Jung et al 1983;Sawai et al 1983;Garleb et al 1988;Garleb et al 1991;Hatfield 1993;Iiyama and Lam 2001). Studies involving various methodologies have consistently indicated that phenolic constituents are among the factors most inhibitory to the digestibility of plant cell wall polysaccharides (Jung et al 1983;Graham and Åman 1984;Hartley and Ford 1989;Borneman et al 1990Borneman et al , 1991Jung et al 1991;Yosef and Ben-Ghedalia 2000;Iiyama and Lam 2001).

These cross-linkages lead to dramatic changes in mechanical properties (Kamisaka et al 1990;Kroon et al 1999) and have been likened to "spot-welding a steel mesh frame" (Iiyama et al 1994).…”

“…Grabber et al (1998) reported that the rate of polysaccharide degradation by rumen microorganisms decreases in the presence of ferulic acid dimers. Hartley and Ford (1989) showed that ferulic acids of cell wall materials negatively influenced the digestibility of cell wall polysaccharides due to the cross-linkages. Graham and Åman (1984) reported that ferulic acid restricted the digestibility of forage by ruminants.…”

. 2005. Hydroxycinnamic acids and ferulic acid esterase in relation to biodegradation of complex plant cell walls. Can. J. Anim. Sci. 85: 255-267. Ferulic acid (3-methoxy-4-hydroxycinnamic acid), present in complex plant cell walls, is covalently cross-linked to polysaccharides by ester bonds and to components of lignin mainly by ether bonds. Ferulic acid has also been shown to occur in dimer-and trimerized forms through oxidative coupling between esterified and/or etherified ferulic acid residues. These cross-links are among the factors most inhibitory to digestion of complex plant cell walls in ruminants. Recently obtained information on ferulic acid and ferulic acid esterases in relation to complex plant cell wall biodegradation is reviewed. A focus of the review is on structural characteristics of plant cell walls associated with ferulic acid, physicochemical properties of ferulic acid esterase and synergistic interaction between ferulic acid esterase and other accessary cell wall degrading enzymes on the release of ferulic acid and plant cell wall biodegradation. L'acide férulique (acide 3-méthoxy-4-hydroxycinnamique) présent dans la paroi cellulosique des plantes évoluées, se lie par covalence aux polysaccharides grâce à des ponts ester ainsi qu'aux composantes de la lignine principalement grâce à des ponts éther. On sait aussi que l'acide férulique se rencontre sous la forme de dimères et de trimères consécutivement à un couplage oxydatif entre ses résidus estérifiés ou éthérifiés. Ces liens croisés figurent parmi les facteurs qui entravent le plus la digestion de la paroi cellulosique des plantes complexes par les ruminants. Les auteurs passent en revue des données récentes sur l'acide férulique et ses estérases, et sur la digestion de la paroi cellulosique des plantes évoluées. Ils insistent en particulier sur les caractéristiques structurales de la paroi cellulosique associées à l'acide férulique, sur les propriétés physicochimiques de l'estérase de l'acide férulique et sur l'action synergique de l'estérase de l'acide férulique et des enzymes accessoires à la dégradation de la paroi cellulosique sur la libération de l'acide férulique et la digestion de la paroi cellulosique par les ruminants.
