The objective of the present study is to determine possible bioactive compounds of the different extract fractions of entire plant of Nyctanthes arbortristis linn. The present research work was carried out by using GC-MS analysis, while mass spectra of the compounds found in the extract fraction was conducted by using the database of national institute of standard and technology (NIST) having more than 62000 patterns.
Forty components from different extract fraction of entire plant were identified. Active principles with their retention time, area, height of peak, percentage of area of peak were obtained. The research reveals the potential of entire plant of Nyctanthes arbortristis Linn as a good source of bioactive such as fatty acid esters, alcohol, hydrocarbon, aldehyde, ketones, amide, terpenes, sterols that justify used of this plant for its various ailments for traditional practitioners.
Keywords: GC-MS, Nyctanthes arbortristis linn, Phytol, Alpha-Comphenol, Extraction, Furfural.
The flowers of Nyctanthes arbortristis linn was used as stomachic, carminative, astringent to bowel, antibilious, expectorant, hair tonic and in the treatment of piles and various skin diseases 1 and in the treatment of ophthalmic purposes 2. The bright orange corolla tubes of the flowers contain a coloring substance nyctanthin, which is identical with α- Crocetin (C20H24O4) from Saffron. The corolla tubes were formerly used for dyeing silk, sometimes together with Safflower or turmeric 3.
Traditionally the powdered stem bark is given in rheumatic joint pain, in treatment of malaria and also used as an expectorant 4. The bark is used for the treatment of snake bite and bronchitis [1, 5]. The resulting paste of Nyctanthes arbortristis on mixing with Arjuna bark is rubbed on the body to treat internal injury and for joint broken bones . Medicinal used for the treatment of various diseases such as sciatica, chronic fever, rheumatism, and internal worm infections, and as a laxative, diaphoretic and diuretic 6. Leaves are used in cough. Leaf juice is mixed in honey and given thrice daily for the treatment of cough. Paste of leaves is given with honey for the treatment of fever, high blood pressure and diabetes 7. Therefore characterization extracts fraction of medicinal plant necessary due to the numerous benefits to the sciences and society.
MATERIAL AND METHODS
The plant Nyctanthes arbortristis linn were collected from local area of Udaipur in the month of January 2011 and authenticated from Department of botany Nagpur University. Voucher specimen no. 9112 was deposited in university.
All solvents used in this present study such as hexane, Petroleum ether, chloroform and methanol were analytical grade.
Nyctanthes arbortristis linn entire plant powders (500g) were extracted with petroleum ether, Chloroform methanol solvent (1000 ml, 72 h) by using successive hot Soxhlet extractor. After extraction, it was filtered and each solvent was evaporated by using rotary evaporator (Yamato Rotary Evaporator, Model RE 801). The solvent free Petroleum ether, Chloroform and methanol crude extract (11.5g, 10.6g, 9.6g respectively) was obtained that was free from particle and dried under vacuum then fractionation by different solvent by formation of three different faction i.e. Petroleum ether, Chloroform, Methanol then send by GC-MS Study.
Preliminary Phytochemical Screening and Fluorescence Analysis
The fresh plants were subjected to shade drying (22oC) for two weeks and then proceed at laboratory mail. Air dried coarsely powder of plant was 1 kg coarse powder was extracted with petroleum ether, chloroform, ethanol and distilled water in soxhlet extractor by continues successive hot method. Finally the extract was collected and concentrated for various qualitative phytochemical tests and fluorescence analysis in observed under UV 366 nm (Table 1) for identification of chemical constituents present in plant material and results were presented (Table 2, 3, 4).
The GC-MS analyses were carried out in Perkin Elmer, auto system XL GC+.
- Carrier gas: helium with a flow rate of 0.7 ml/min.
- Column temperature : 5minute in 180oC, 180-260oC at 3oC/min., 5minute in 260oC, 260-280 at 0.2oC, and finally 5 in 280oC injector temperature 280oC to 290oC detector temperature.
- Volume injected: 1μL of sample
- Ionization potential: 70 eV

Identification of compound GC-MS chromatogram of Petroleum ether fraction, Chloroform fraction and methanol fraction of Nyctanthes arbortristis linn (Figure 1, 2, 3) showed peaks indicating the presence of 40 phyto-constituents. Interpretation of mass spectrum and GC-MS was conducted by using the database of national institute of standard and technology (NIST) having more than 62000 patterns (Figure 1, 2, 3, 4, 5, 6 and Table 2, 3, 4).
Identification of Compounds
The identity of the compounds in the extract was assigned by the comparison of their retention indices and Interpretation of mass spectrum and GC-MS was conducted by using the database of national institute of standard and technology (NIST) having more than 62000 patterns.
RESULTS AND DISCUSSION
The bioactive compounds present in the different extract fraction of entire plant of Nyctanthes arbortristis linn. The active principles with their retention time (RT), area, height, percentage of area and their structure were presented.
