Abstract(s)
Salt-tolerant plants, also known as halophytes, could provide a novel source of feedstock
for biorefineries. After harvesting fresh shoots for food, the lignified fraction of Salicornia ramosissima
J. Woods could be used to produce bioactive botanical extracts for high-value industries such as
nutraceuticals, cosmetics, and biopharmaceuticals. The residual fraction after extraction can be further
used for bioenergy or lignocellulose-derived platform chemicals. This work analysed S. ramosissima
from different sources and growth stages. After pre-processing and extractions, the obtained fractions
were analysed for their contents of fatty acids, pigments, and total phenolics. Extracts were also
evaluated for their in vitro antioxidant properties and inhibitory effect towards enzymes related to
diabetes, hyperpigmentation, obesity, and neurogenerative diseases. The ethanol extract from the fibre
residue and the water extract from completely lignified plants showed the highest concentration of
phenolic compounds along with the highest antioxidant potential and enzyme-inhibitory properties.
Hence, they should be further explored in the context of biorefinery.
