Lebialem, South West region of Cameroon; (4°10′N 9°14′E/4.167°N 9.233°E)	Not reported	Crude extracts: Analgesic and anti-inlammatory effect of aqueous extract of the stem bark [14]; crude methanol fruits extracts (40 μg/mL) showed to inhibit growth of CCRF-CEM leukemia cells at about 50 % [16].
Gladiolus quartinianus A. Rich (Iridaceae); 17260/SRF/Cam	Infections of the skin, gut, urogenital system, and upper respiratory tract [17], gonorrhea, infectious conditions, constipation and dysentery [18].

Combretum molle R. Br. ex G. Don (Combretaceae); 33311/ HNC	Fever, abdominal pains, convulsion, worm infections, human immunodeficiency virus (HIV)/acquiredimmune deficiency syndrome (AIDS) related infections [19]; hookworm, snake bite, leprosy, dysentery, general body swellings, arthritic and other inflammatory conditions, sterility, constipation [20, 21]; Parasitic, protozoan, infectious diseases [22], malaria [23]	University of Dschang, West region of Cameroon; (6°30′N 10°30′E/6.500°N 10.500°E)	Mollic acid glucoside [21]); β-D-glucopyranosyl 2α,3β,6β-trihydroxy-23-galloylolean-12-en-28-oate,combregenin, arjungenin, arjunglucoside I, and combreglucoside [24] .
