Abstract(s)
This work searched for the phyto-therapeutic potential and nutritional value of seeds
from the halophyte Cladium mariscus L. (Pohl.), aiming at its use as a source of bioactive ingredients
for the food industry. Hence, the nutritional profile, including minerals, of seeds biomass was
determined; food-grade samples were prepared, and their phytochemical fingerprinting assessed.
Extracts were evaluated for in vitro antioxidant potential, inhibitory capacity towards enzymes related
to neuroprotection, diabetes, and hyperpigmentation, and anti-inflammatory properties, along with a
toxicological assessment. Sawgrass seeds can be considered a proper nutritional source with a good
supply of minerals. All extracts had a high level of total phenolics (65.3–394.4 mg GAE/g DW) and
showed a chemically rich and diverse profile of metabolites that have several biological properties
described (e.g., antioxidant, anti-inflammatory). Extracts had no significant toxicity (cell viabilities
> 80%) and were overall strong antioxidants (particularly at radical scavenging and reducing iron),
effective tyrosinase inhibitors (55–71 mg KAE/g DW), showed anti-inflammatory properties (30–60%
NO decrease), and had moderate capacity to inhibit enzymes related to neuroprotection (AChE
3.7–4.2, BChE 4.3–6.0 mg GALE/g DW) and diabetes (α-glucosidase 1.0–1.1, α-amylase 0.8–1.1 mmol
ACAE/g). Altogether, results suggest that sawgrass seeds have the potential to be exploited as a new
food product and are a reservoir of bioactive molecules with prospective applications as ingredients
for value-added, functional, and/or preservative food products
