3.2 Chemical Compositions Comparison in Both Extracts
The tentative chemical compositions of two crude extracts were analyzed using GC-MS (Figures 6 & 7). The
percentages of major components of the extracts are given in Table 2 and 3, which demonstrated an interesting
concoction of compounds with significant antimicrobial activity. According to the results from the GC-MS
(Tables 2 & 3), it is clear that some compounds were present in both extracts which were: cyclobutanol (91.7%)
(Alaaddin et al., 2001); cyclopropyl carbinol (84.5%) (Lumir et al., 2008); alanine (80.9%) (Li et al., 2012);
(r)-(-)-2-amino-1-propanol (80.5%); 4h-pyran-4-one,2,3-dihydro-3,-dihydroxy-6-methyl (92.5%) reported as an
odor compound (Preininger et al., 2009) and based on previous studies, several important biological activities of
this compound were observed by several researchers such as anti-mutagenic activity agent against arylamine and
2-acetoxyacetylaminofluorene (2AAAF)-induced DNA damage in Chinese hamster ovary cells, (Berhow et al.,
2000), anti-alpha-glucosidase activity in patients with diabetes mellitus, (Quan et al., 2003), reactive oxygen
scavenging activity agent (Takara et al., 2007) and also anti-tumour activity (Ban et al., 2007);
1,3-dioxolane-4-methanol,2,2-dimethyl (88.6%) reported as antimicrobial agent (Daniela et al., 2009) ;
pyrimidine-2,4(1h,3h)-dione,5-amino-6-nitroso (82.6%); butanenitrile,2,3dioxo,dioxime,o,o-diacetyl (805%);
1,6,3,4-dianhydro-2-deoxy-beta-d-lyxo-hexopyranose (81.3%); 2-heptanamine,5-methyl (82.1%) and
benzaldehyde, 4-ethoxy (80.2%) (Table 2) in which some of them were reported to be antimicrobial agents
(Ahmedzade et al., 2003).
