“…Soluble phenolic acids have been shown to be abundant in a variety of seagrasses (Zapata & McMillan, 1979;Buchsbaum et al, 1991). Phenol rich seagrass indicated that extracts may have antioxidant activity and antimicrobial activity which may help in preventing a number of diseases through free-radical scavenging activity (Harrison & Chan, 1980;Anggadiredja et al, 1997;Ruberto et al, 2001;Vasanthi et al, 2006). The amount of tannin in the seagrass was found in the average level (2.940-9.800 mg/g) corroborated with the earlier study on seagrasses (Athiperumalsami et al, 2008).…”

“…Three groups of blades in a dark bottle served as a control. Harrison (1978) showed that for intact Zostera americana plants only 6.5% of the total fixed 14C was translocated out of the blades during a 3-h incubation. Clipped HaZoduZe blades continued to grow for more than a week in our laboratory.…”

“…Soluble phenolic acids have been shown to be abundant in a variety of seagrasses (Zapata & McMillan 1979, Buchsbaum et al 1991 and seagrass extracts rich in soluble phenols have been found to inhibit the growth of bacteria and algae (Harrison & Chan 1980). Esterbound phenols may be linked to lignin (Higuchi et al 1967) or cell-wall carbohydrate (Hartley 1973), and are degraded at considerably lower rates than soluble phenols (Wilson et al 1986).…”

Senescent blades from the seagrass Halodule wrightii Aschers were suspended in the water column of Laguna Madre (Texas, USA) for a period of 419 d , representing the longest seagrass decomposition study to date. The initial stage of decomposition was characterized by a rapid loss of organic matter (36 % in 24 d ) attributed to leaching. A total of 76 % of the organic matter from seagrass tissues was lost by the end of the decomposition period. Of the major bulk constituents measured, neutral sugars were most abundant and accounted for 23 % of the ash-free dry wt of the initial senescent material. A complete and early loss of the cyclitol, myo-inositol, a reduction in glucose yields, and a relative enrichment in mannose were the most dynamic features of the neutral sugar fraction. An overall stability series: mannose > fucose > arabinose = rhamnose = galactose = xylose > glucose, reflects patterns of selective degradation of the polymers from which these sugars are derived. Soluble and ester-bound phenolic acids were lost from tissues at relatively high rates. Susceptibility of individual phenolic acids to removal from bulk tissue upon treatment with weak base correlated well to initial losses in the field. Early changes in total CuO oxidation phenol yields from H. wrightii were caused pnmarlly by the relatively rapid loss of soluble and ester-bound phenolic acids. Therefore, we took a new approach to quantlfy lignin-derived phenols by subtracting soluble and ester-bound phenols from total CuO oxldat~on ylelds. When these losses were taken Into account, lignin-derived phenol yields were similar from freshly senescent and highly degraded detntus. Cutln, although initially selectively preserved relative to bulk tissue, was also found at near initial yields In the highly degraded detritus. Overall, the distribution of polymeric constituents (cellulose, hem~cellulose, lignin and cutin) was similar in freshly senescent and highly degraded tissues suggesting that the compounds which comprise the ultrastructure of H, wrightij are degraded at similar rates Photobleached H. wriglitii blades were characterized by a much higher neutral sugar content, slmilar levels of cutin acids and a nearly complete absence of phenols con~pared to freshly senescent tissue. Photobleaching appears to be an important degradative mechanism which yields a polysaccharide-rich detritus that is devoid of the lignin signature characteristic of vascular plant tissues.
