ABSTRACT
The leaf and stem
bark of Pentaclethrä macrophylla and the leaves of Newbouldia laevis were
analyzed for their phytochemical and anti-microbial properties. The GC-MS
analysis of the stem bark of Pentaclethra macrophylla yielded 10 compounds:
1,2,3- benzenetriol (11.53 %), 1, 4 — methoxy -3- (4- methyl phenoxy) phenyl
ethanone (2.31 %) , 1,2-benzenecarboxylic acid (2.31 .%) , 3-eicosene (2.31 %),
hexadecanoic methyl ester, (4.62 %), n-hexadecanoic acid (20.77 %),
6-octadecenoic acid methyl ester (5.38 %), 6-octadecanoic acid, (25.77 %),
octadecanoic acid (13.25 %) and naphto [-1, 2, 6-] furan -2-one (10.38 %).The
following compounds were identified from the leaf of Newboudia laveis; 2-
phenoxy ethyl beta -2- phenoxy ethyl-3 -phenyl propànoate (1.41%), benzene-(1-methyl
nonadecyl) (1.41 %), 6-phenyl undecane (1.06%), Eicosyne (2.47 %), hexadecanoic
acid methyl ester(13.73 %), nhexadecanoic acid (9.16%), z-octadecanoic acid
(22.81 %) ,9-octadecanoie acid (22.81 %) phytol (23.51 %) Oleic acid (10.56 %)
, octadecanoic acid. (5.97 %) ,squalene (7.75 %) Analysis of the leaf of
Pentaclethra macrophylla gave 8 compounds ; , -2, 15 —octadecedien - 1-ol
acetate (6.90 %) ,hexadecanoic acid (3.14 %), n-hexadecanoic acid (10.69%), 6-
octadecenoic acid (13.84 %) ,octadecanoic acid (8.18 %), (.2H) phenanthrenone
(42.14 %) ,Pregnan-2-one (6.29 %) and -4-methylene-1-methyl-2- (z— methyl
1-propene -1- yl) cyclo hexane (9.43. %). The extracts showed marked inhibition
of the growth of seven selected pathogens; Pseudomonas aeruginosa,
Staphylococcus aureus, Escherichia coli, Salmonella typhi, Candida albicans,
Penicillium and Aspergillus niger. 13 — Benzyl ethyl methyl abietate was
isolated from the stem bark of Pentaclethra macrophylla, the structure was
elucidated using spectrum obtained from 'H and '3C NMR, IR and Mass
Spectrometer. The compound 4, 15 — chloestene -3-yl-benzoate was also isolated
from the leaf of_Pentaclethra macrophylla using similar analytical tools.
