  1. * The three letter codes represent the 'plant, plant part, and solvent' respectively e.g. MLH represents 'Margaritaria discoidea, leaves, hexane' extract. The extraction solvent and plant part letter codes are shown in parentheses. The yields of crude extract range from 0.18% in Margaritaria discoidea stem bark hexane extract (MBH) to 2.12% in Margaritaria discoidea leaves methanol extract (MLM).
