Abstract: The diagnosis of powdered liana bark from Landolphiaowariensis (Apocynaceae). This is a micrographic and granulometric study of the powder. The organoleptic parameters have been appreciated. Elements were identified under an optical microscope. The particle size distribution was carried out by sieving and laser microscopy. Characteristic elements of the powder have various geometric shapes. The sizes vary from 0.3 to 0.35m. The powder is fine. The waist line looks like a bell. The mean, mode and median coincide on the same size. Thus the distribution is normal, the studied powder is homogeneous, not adulterated.

Keywords: Landolphiaowariensis, micrograph, granulometry
