| Summary: | Polysaccharide was extracted from the leaves of (Molokhia) Jew’s-mallow by hotwater extraction using trichloro acetic acid(TCA) to removal of protein from the
polysaccharide ,precipitation with ethanol, and obtained a polysaccharide yield from
4.2% based on wet weight source. The biochemical composition of the polysaccharide
contains total carbohydrate,sulfateandprotein77.6%, 8.6%, 0.63%, respectively.
Phytochemical tests were carried out for polysaccharide. The previous studies
indicated the presence of glycoside, phenol and tannin in polysaccharide from Jew’smallow. However, the presence of both alkaloids and saponins was not observed .The
Fourier transform infrared (FTIR) spectral analysis of the polysaccharides consist of
carboxyls and sulfate groups.The anticoagulant activity of polysaccharide was
evaluated by activated partial thromboplastin time (APTT) and prothrombin time (PT)
assays with respect to heparin The results obtained by APTT assay, through the
increase in coagulation time, the increase in blood coagulation time with increased
polysaccharide concentration, the 100 μg/ml polysaccharide concentration had the
longest time of 210Sce and was compatible with the concentration of1000 (IU/ ml) of
heparin.However the time of PT did not have any apparent effectiveness in increasing
the time of coagulation at all concentration compared with heparin. |
