Abstract
Polygonum minus or ‘kesum’ is a traditional Malaysian plant used as flavoring agent and recommended for digestive disorders as well as stomach pain. The leaves are often eaten fresh as a vegetable (salad and ulam), especially among the Malay communities for preventive health care. The physicochemical characterization of nanosize of Polygonum minus in wet mill and dry mill was influenced by ball milling process using planetary ball mill. Particle size analysis employing photon correlation spectroscopy was carried out to record the effect of milling parameters on the particle size produced. Fourier Transform Infra-Red (FTIR) spectrum was recorded for functional groups analysis. The result showed that after ball milling, the average size of particles was reduced while FTIR results showed the peak at region of 1,600-1,500 cm-1 is due to the stretching vibration of carbonyl group and 1300-1,000 cm1 indicate a stretching of C-H group.
