|Abstract: ||The marine
phanerogam Syringodium filiforme, known as “manatee grass”, is a common species that grows in coastal areas
associated to Thalassia testudinum. With the aim to describe some of its possible chemical characteristics, this
study was performed with a sample of 1.2kg, collected in March 2009, in Guanabo beach, Havana, Cuba. The
sample was dried (less than 12% humidity) and a total extract prepared; other three extracts were prepared with
the use of solvents of increasing polarity. The phytochemical screening and analytical determinations of each
fraction were undertaken Total polyphenol content was determined using pyrogallol as reference´s standard;
chlorophyll a and b and anthocyanin content were also quantified. Total extract and fractions antioxidant activity
were evaluated by using the free radical scavenging activity assay with 1,1-Diphenyl-2-Picrylhydrazyl reactive
(knowing as DPPH´s method). The phytochemical screening of the different extracts detected the presence of
high concentrations of flavonoids, phenols, terpenes, antocyaninns, reducing sugars and alkaloids. The total
extract and methanol fraction showed significant free radical scavenging properties, while the petroleum ether
fraction showed moderate activity, and the chloroform fraction and the aqueous soluble precipitate (residual
salt) obtained didn’t show antioxidant properties against free radicals. The results of this work confirmed the
potentialities of this species for biological purposes|
