“…We have recently shown that S. filiforme detrital leaves are a source of L-chiro-inositol (Nuissier, Diaba, & Grignon-Dubois, 2008). In continuation of our studies toward the evaluation of seagrasses as a new source of bioactive compounds, we focused on phenolic compounds.…”

“…Similarly, thalassiolins A, B and C were isolated from Thalassia testudinum [17] as anti-HIV agents. L-Chiro-inositol was isolated from Syringodium filliforme [18]. Detritus of seagrasses Zostera noltii and Zostera marina was screened as a new source of zosteric acid [19] and rosmarinic acid [20].…”

This paper discusses the determination of minerals content (cadmium, cobalt, chromium, copper, nickel, lead, manganese, magnesium, iron, zinc, sodium, potassium and calcium) of six seagrass samples, Enhalus acoroides, Thalassia hemprichii, Halodule pinifolia, Syringodium isoetifolium, Cymodocea serrulata and Cymodocea rotundata using inductively coupled plasma optical emission spectrophotometry and flame photometer. Principal component analysis (PCA) and hierarchical cluster analysis revealed different mineral compositions of the seagrass samples. Among the 13 elements investigated, Ni 1.513, Na 690.167 and Ca 220.333; Cr 3.957; Mn 23.427, Zn 17.593 and Fe 156.567; Cd 0.357, Co 0.431, Pb 2.040, Mg 912.733 and K 300.9; Cu 7.8 mg/kg dry weight, respectively, were found at high concentrations in E. acoroides; T. hemprichii; H. pinifolia; S. isoetifolium and C. rotundata. PCA analysis confirmed the presence of three components with 91.28% of the total variance. The toxic elements Pb, Cr and Cd were also found in all six seagrasses, although the concentrations were below the permissible limits proposed by the World Health Organization.

“…A pure sample of LCI (72 mg) was isolated from a crude aqueous extract of C. nodosa (12 g), following the silylation-desilylation process we have previously developed [25]. The purity was confirmed by 1 H NMR and the rotatory power was measured on a Perkin Elmer 241 polarimeter at 25°C ([α] D 25 = -67.8, c = 0.5, H 2 O).…”

“…We have recently reported the isolation of LCI and CA from the dead biomass of the tropical seagrass Syringodium filiforme [25,26], and CA from the temperate Cymodocea nodosa [27]. Considering the economic potential of these two substances within the pharmaceutical, cosmetic, and food industries, it appears of interest to evaluate the potential of other tropical members of Cymodoceaceae.…”

Background: Detrital leaves from seagrass of the Cymodoceaceae family were assayed for biologically active molecules that have commercial as well as societal benefits. Objective: We focused on L-chiro-inositol, a very rare natural occurring cyclitol, and chicoric acid, a polyphenolic compound, in which both applications were found in the nutraceutical segment. Method: Six species of seagrass belonging to the genera Syringodium, Cymodocea and Halodule were collected from their native habitat. The L-chiro-inositol content of the crude aqueous extracts prepared from different batches of Cymodocea nodosa flotsam was measured by quantitative 1H-NMR spectroscopy. High concentrations were found with values ranging from 22.2 to 35.0 mg.g-1 plant dw. The presence of L-chiro-inositol in the tropical species C. rotundata, C. serrulata, Syringodium isoetifolium, and Halodule pinifolia was also characterized by qualitative NMR. The chicoric acid content of crude aqueous methanolic extracts prepared from C. rotundata, C. serrulata, S. isoetifolium, and Halodule pinifolia was determined by quantitative HPLC-DAD. The values found ranged from 0.39 to 6.15 mg.g-1 dry weight. Chicoric acid was unambiguously identified as the major phenolic in S. isoetifolium, and Halodule pinifolia, while it was found in mixture with flavonol derivatives in C. rotundata and C. serrulata. Flavonol derivatives are also of interest for their bioactivity. Result: Considering the demonstrated therapeutic applications of L-chiro-inositol and chicoric acid, their high value on the nutraceutical market, and their rare occurrence in the plant kingdom, their presence in Syringodium, Cymodocea and Halodule detrital leaves makes this abundant biomass of interest for dietary and pharmaceutical applications. Conclusion: These results show that there is a real potential for harvesting beachcast Cymodoceacea.
