INTRODUCTION n Egypt, there are many kinds of tree species planted as street trees, windbreaks and shelterbelts and there are large quantities of wood branches and leaves resulted annually from the pruning process to street trees such as Ficus species and ornamental trees. Therefore, these materials can be used as a useful source for the production of phytochemical substances. I Ficus is a genus of about 800 species and 2000 varieties belongs to family Moraceae occurring in tropical and subtropical forests [1]. Studies on Phytochemical analysis of some Ficus species revealed the presence of phenolic compounds as the major components [2,3,4,5]. Ficus retusa L. (F. nitida Thunb.) or (F. microcarpa L.) commonly known as Chinese anyan is a large evergreen tree and distributed throughout Central India and Australia. Previously it have been reported that the aerial part of F. retusa had a cytotoxic and antifungal activities [6,7]. Additionally, the golden yellow leaves was found to have a high amounts of *Corresponding author (zidan_forest@yahoo.com) flavonoids, carotenoids, triterpenoids, fatty alcohol, steroids, coumarins, flavane-4-hydroxybenzoate and isoflavones [8,9,10]. Mahmoud et al. [11] found a significant inhibitory activity when F. nitida mixed with virus inoculum or applied 48 h before challenge. Dalbergia sissoo Roxb. belongs to family: Fabaceae is commonly known as Indian rosewood [12]. The extract was found to possess antidysentric [13], analgesics and antipyretic [14]. The bark and extracts of wood are bitter used as aphrodisiac, abortifacient, expectorant, antihelmintic and antipyretic [15]. The phytochemical analysis of D. sissoo reported the presence of alkaloids, carbohydrates, saponins, flavonoids, glycosides and steroids [12,15,16]. The extracts from stem bark have been reported to have a good antioxidant activity [17]. From the previous study [18] it was reported that the extracts from F. retusa and D. sissoo had a good antibacterial activity, so that the present study showing the GC/MS analysis of ethyl acetate fractions from the methanol extract of wood and leaves from D. sissoo and F. retusa, respectively. II. MATERIALS AND METHODS Tree material From the previous study [18], the wood and leaves of F. retusa and D. sissoo, respectively, were collected from different locations at Alexandria City, Egypt. Plant vouchers were kindly identified and stored for deposition at the Department of Forestry and Wood Technology, Faculty of Agriculture, Alexandria University. Preparation of extracts The different parts were air-dried under room temperature, ground to fine powder, placed on polyethylene bags and kept away from moisture in a dried place until use [19]. Powdered plant materials (50 g) was extracted with 500 mL of methanol (80%) for 8 h using Soxhlet extractor apparatus at 40°C and the J OURNAL OF FOREST PRODUCTS & INDUSTRIES, 2013, 2(3), 34-41 ISSN:2325–4513(PRINT) ISSN 2325 - 453X (ONLINE ) 35 solvent was evaporated under reduced pressure. The extracts at 4°C until use. The methanol extract from each part was subsequent partitioned using separating-funnel into ethyl acetate, n-butanol and water. These fractions were separated with solvent/solvent group separation procedure [18,20]. The quantification of methanol extract and ethyl acetate fraction from F. retusa leaves and D. sissoo wood was (60.52, 4.22 g/kg o.d.) and (43.19, 6.59 g/kg o.d.), respectively. Chemical Constituents of Fractionated Extracts by Gas Liquid Chromatography/Mass Spectrometry (GC-MS) Apparatus Accordingly, identification of the chemical constituents of fractionated extracts were made using HB5890 gas liquid chromatography (GLC) coupled with HB5890B series mass spectrometer (MS) at Central Lab. Unit in High Institute of Public Health, Alexandria, Egypt. The gas liquid chromatography was equipped with a split less injector at 280ºC, and a flame ionization detector (FID) held at 300°C using helium as a carrier gas. Samples were separated on a capillary column (30m long, and 0.25mm internal diameter) HP-5 (Avondale, PA, USA) of 0.25μm film thickness. The temperature of the gas chromatograph column was programmed from 80°C to 100°C at a heating rate of 15°C /minute, and then increased to a maximum final temperature of 310°C at a heating rate of 5ºC/minute, holding the maximum final temperature for a residence time of 10 minutes. The temperature of ion source in the mass spectrometer was held at 200°C. All mass spectra were recorded in the electron impact ionization (EI) at 70 electron volts. The mass spectrometer was scanned from m/z 40 to 410 at a rate of two scans per second. An integrator automatically calculated peaks areas. Neither internal nor external chemical standers were used in this chromatographic analysis. were lyophilized, weighed and stocked in sealed vials Interpretation the resultant mass spectra were made using a computerized library searching program, and by studying the fragmentation pattern of such compound resulted from mass spectrometry analysis. III. RESULTS AND DISCUSSION Suggested chemical components found in the ethyl acetate fraction extracted from F. retusa leaves F. retusa is a widely distribution tree in streets and roads of Alexandria, moreover, there are large quantitative of leaves resulted annually from pruning process that can be used in various purposes. The chemical composition of the ethyl acetate fraction derived from the methanolic extract from F. retusa leaves, which had 19 organic compounds, were identified by means of GC-MS method. Figure 1 showed the chromatogram chart of these chemical components found in the ethyl acetate fraction. Table 1 presented the characterizations (compound name, retention time, chemical formula, molecular weight and the peak area or yield of the components) of the chemical composition of this fraction. The main compounds presence in the ethyl acetate fraction from the leaves of F. retusa, were 1,2-benzenedicarboxylic acid-dibutyl ester (15.19%); this component was found to have a good antibacterial activity against certain Gram-positive and Gram-negative bacteria [21], phenol,4-(2-aminopropyl)-, (+/-) (9.27%) and R-(2,2,3,3-2H4) butyrolactone (13.24%). Furthermore, the mass spectra (MS) and chemical structures for these compounds were showed in Figures 2, 3 and 4 with the molecular weight (MW) 278, 90, and 151 respectively.
