The chemical constituents of H. suaveolens comprise of essential oils and a few triterpenes (49, 50, 51, 52). Iwu et al. (53) identified in the steam distilled oil 32 terpenoid compounds. The major compounds were limonene thujane, a.-pinene, a.-phellandrine, 3-cyclohexen-l-ol, 4-methyl-l-(l-methylethyl)-3-cyclohexen-1 -ol, 3 -cyclohexen-1 -carboxyaldehyde, elemene, 4,11,11 -trimethyl-8-methylene-bicyclo[7.2.0]undec-4-ene, octahydro-l,4-dimethylazulene, 5.a., 8.p.,H-9.p.,H-10.a.-labd-14-ene 5.a-androst-9(ll)-en-12-one and 5.a.-androstan-2,ll-dione. Fun et al. (54) showed by GC analysis that the oil has high contents of 1,8-cineole (27-38%) and sabinene (12-18%). Analysis of the oil by Thoppil and Jose (55) showed the presence of citronellyl acetate, fl-caryophyllene, piperitone oxide and geranyl acetate. Zollo et al. (56) reported that the most abundant compounds in the oil collected from Cameroon were hydrocarbons (> 58%). Tchoumbougnang et al. (57) reported the presence of sabinene (20.6%), yff -caiyophyllene (17.5%) and bergamotol (10.9%) as the...
