that may grow at times as a shrub of 4 m in height. The leaves are lanceolate
to oval and alternately arranged. Flowers are solitary in the axils of leaves.
Compounds and activities: The oleonone-type triterpenes isolated from this
species include (23Z)-feruloyl hederagenin, (23E)-feruloyl hederagenin,
β-amyrin acetate, and β-amyrin palmitate (Chang and Kuo, 2007). The
extracts of this plant species possess antioxidant, antidiabetic, and immu-
nosuppressive properties. The methanol leaf (80%) extract gave the lowest
minimum inhibitory concentration (62.5 µg/ml) and minimum bactericidal
concentration (125.0 µg/ml) against E. coli 0157:H7, E. coli ATCC 25922,
and Bacillus spizizenii (ATCC 6633) (Yakob et al., 2012). This species
