Anticoagulant Activity of Polyphenolic-Polysaccharides Isolated from Melastoma malabathricum L.

Figure 3

FT-IR spectrum of F1, F2, and F3. Active anticoagulant fractions F1, F2, and F3 were purified by solid phase extraction (SPE) from Melastoma malabathricum Linn. leaf hot water crude extract, and fractions were determined to have significantly prolonged activated partial thromboplastin time (APTT). Red line represented F1. Green line represented F2. Blue line represented F3.
