“…The leaves consist primarily of polysaccharides (roughly 60%, two thirds of which corresponds to holocellulose), and the remaining material is largely composed of various phenolic constituents, more specifically lignin, tannin and free and ester-bound phenolic acids (Zapata and McMillan 1979;Agostini et al 1998;Arnold and Targett 2002;Torbatinejad et al 2007). Reported lignin contents of P. oceanica leaves and agaepropili are in the range of 25-30% of their dry weight (Ncibi et al 2009;Khiari et al 2010;Bettaieb et al 2015).…”

“…Lignin synthesis by land plants has been observed as a direct response to microbial infection or physical wounding (Matern et al 1995, Hawkins & Boudet 1996, Dushnicky et al 1998). Other phenolic compounds that commonly occur in seagrasses are believed to have comparable antibiotic properties (Zapata & McMillan 1979, Harnson 1982, Buchsbaum et al 1990, Agostini et al 1998. Increased levels of these compounds in leaves of Zostera manna have been observed as a response to pathogenic infection (Vergeer & Develi 1997).…”

“…Caution should be exercised not to assign non-lignin phenols as part of the lignin structure. Since phenolic compounds are abundant in seagrass tissues (Zapata & McMillan 1979, Harrison 1989, Agostini et al 1998, correction for these substances is required. This is preferably done by elimination of soluble phenols prior to analysis.…”

Using Curie-point Pyrolysis Gas Chromatography Mass Spectrometry [Py-GCMS) and Direct Temperature-resolved Mass Spectrometry (DT-bfS), lignin was detected In highly purified preparations (Milled Wood Lignin = hlWL) of various tissues of the seagrasses Zostera rnarina and Posidonia oceanica. The results ind~cate that P. oceanica contains more lign~n than Z. manna and that roots and rhizomes generally contain more Lignin than leaves. It is concluded that the ability to produce lignin is not lost by the angiosperm ancestors of extant seagrasses upon their colonization of the marine environment. Relative lignin abundances in the different tissues appear to be posltlvely correlated with life span. It is suggested that lignification contributes to the longevity of a tissue by protecting lt against microbial attack, but that deposition of lignin in seagrasses is restricted to tissues that show limited growth.

“…We do not know what the chemical feeding deterrents are present in H. durvillaei or E. acoroides, and we are currently examining the extracts for secondary metabolites. Halophila minor and other seagrasses from Guam have been reported to contain phenolic acids (Zapata & McMillan 1979).…”

ABSTRACT. The role of algal secondary metabolites in determining feeding preferences of adult and juvenile rabbitfish Siganus argenteus was examined in outdoor tanks on Guam. Secondary metabolites could not explain the preferences of these herbivores, although the presence of secondary metabolites appeared to account for the low palatability of some seaweeds, such as Tydemania expeditionis and Microcoleus lyngbyaceus. Other species, including Desmla hornemanni and Halimeda discoidea, that contained secondary metabolites with feeding-deterrent properties were of medium preference. Further species that produced secondary metabolites, including Asparagopsis taxiformis, Caulerpa spp., Chlorodesmis fastigiata, Dictyota spp., and Lragora fannosa were rapidly eaten, and neither their extracts nor their isolated metabolites significantly deterred grazing. Responses to algal chemistry differed between adults and juveniles. Juvenile S. argenteus were not deterred by extracts of T. expeditionis, Halymenia durvillaei, H. discoidea, and Enhalus acoroides, or the isolated metabolites chlorodesmin and flexihn that deterred the adults. As regards morphological defenses, several calcified seaweeds were of mehum preference for both adult and juvenile rabbitfish; however, none of the highpreference seaweeds were calcified, and calcification and toughness were associated with low feeding preference.
