Citharexylum spinosum is an aromati

Citharexylum spinosum is an aromatic plant
belonging to Verbenaceae family. Citharexylum genus
contains approximately 70 species which is found in
Bermuda, West Indies, and southern United States
through Mexico to South America [1]. Normally, it is
cultivated as a street tree which is a popular
ornamental, primarily in tropical and subtropical areas
of the world as an ornamental for its fragrant white
flowers and attractive foliage [2]. There are many
common names including Florida fiddlewood and
Spiny fiddlewood [3]. Common name of Fiddlewood
is obtained from the use of its wood making stringed
instruments by the people of the Caribbean .C.
spinosum is also used in cabinetry [2, 4]. This plant
can be grown height up to 15 m. The ovate to elliptic
leaves are 4-20 cm length. It also contains orange
petioles. Small white flowers are produced throughout
the year on hanging axillary and terminal racemes and
panicles 20-40 cm in length [5, 6]. Various classes of
natural compounds are produced by plants. These
components contain the different purposes according
to functional group appeared in their structure. At least
1,700 compounds are in a class of volatile components
[7, 8]. These volatile compounds such as terpenoids,
fatty acid derivatives, indole and benzenoids play
important role for plant reproduction by attraction of
insects [9-11]. Moreover, isolated aroma compounds
are used as ingredients in perfume and food
industries [9]. The study of volatile compounds in
plants is performed by using solid phase
microextraction (SPME) which is a solvent-free
adsorption/desorption technique. It is applied in many
applications such as investigation of odor components
in foods and beverages [12, 13]. It consists of coated
fibers that are used to extract and concentrate target
compounds form the sample [12]. After extraction, the
fibers are transferred to analyze the target compounds
by gas chromatographic (GC)[12, 13]. Keene [13]
proposed the amount of analyte adsorbed by the fiber
depends on the thickness of the coating and on the
distribution constant of the analyte. The extraction
time is dependent on the period of time required to
obtain precise extractions for the analytes with the
highest distribution constants. Type of fiber is the
important key for improving the extraction efficiency
of SPME. Polarity of target compounds should be
similar to those coated on SPME fiber [13]. A thick
phase coat is the most suitable for extracting volatile
compounds, while a thin coat is the most effective for
adsorbing/desorbing semi-volatile compounds [12]. It
has gained widespread acceptance in many areas in
recent years [14-16].
According to the advantage of SPME, highly
volatile compounds of C. spinosum flowers were
extracted and analyzed by SPME c GC-MS. Three
fibers are applied in this study including 100 µm
PDMS fiber, 75 µm CAR/PDMS fiber and 30 µm
DVB/CAR/PDMS. The quantitative analysis of all
identified highly volatile compounds was also
described.
