Abstract	Plantain seed is a commonly used medicinal herb, which has been used in traditional medicine. Physical properties are useful information for designers of processing equipment and for industrial processing of plantain seeds. Physical properties of plantain seeds were determined as a function of moisture content by image processing method. Several properties were obtained in the moisture range from 6.44% to 19.95% dry basis. The results showed that the length, arithmetic and geometric diameter of seeds increased from 0.300 to 0.330 mm, 0.222 to 0.276 mm, and 0.231 to 0.280 mm, respectively. The thousand-unit mass increased from 0.205 to a maximum value of 0.230 g, the surface area increased from 0.282 to 0.418 mm2, the porosity increased from 50.46% to 60.30%. The value of empting angle of repose was found to increase from 36.4° to 48.2° and the value of filling angle of repose was decreased gently from 38.9° to 36.8° . As moisture content increased from 6.44% to 19.96% (d.b), the static coefficient of friction for surfaces of iron, galvanized and wood showed an increase of 29.75%, 20.99% and 48.80%, respectively. The results showed that the bulk density decreased from 666.6 to 526.9 kg/m3 and the true density decreased to a minimum value of 1310.6 kg/m3 at moisture content of 15.06% (db).
