The essential oil isolated from the flowers of Alstonia scholaris and growing all over the country of Bangladesh, was analyzed by gas chromatography-mass spectrometry (GC-MS). Sixty compounds were identified in the flower oil. The essential oil compositions of flower oil 2-Dodecyloxirane (31.83%), Benzene, 1,2-dimethoxy-4-(2-propenyl)- (8.49%), Spinacene (6.09%), 1,54-Dibromotetrapentacontane (5.13%), 2,6,10,15-Tetramethylheptadecane (4.91%), Terpinyl acetate (3.74%), Linalool (2.22%), Tritetracontane (2.17%), 1-Cyclohexanol, 2-(3-methyl-1,3-butadienyl)-1,3,3-trimethyl- (1.78%), 9-Methyl-5-methylene-8-decen-2-one (1.58%) as the main constituents.

Essential oil obtained by hydro-distillation from fresh leave of Alpinia nigra was analyzed by Gas Chromatography Mass Spectrometry (GC-MS). Fifty three compounds were identified in the leaf oil. The main essential oil compositions were 1,5,9,9-Tetramethyl-1,4,7-cycloundecatriene (24.92%), 6,6-Dimethyl-2-methylenebicyclo[3.1.1]heptanes (12.90%), 5-Amino-6-(2 fluoroanilino)furazano[3,4-b]pyrazine (12.18%), 4,11,11-Trimethyl-8-ethylenebicyclo[7.2.0]undec-4-ene (10.76%), 6-(3-Fluorobenzyl)-1,2,3,4,5,6-hexamethyl-2,4-cyclohexadien-1-ol (5.77%), 1,6,10-Dodecatrien-3-ol, 3,7,11-trimethyl-, (E)-(5.41%), Caryophyllene oxide (2.61%), 5,5-Dimethyl-4-[(1E)-3-methyl-1,3-butadienyl]-1-oxaspiro[2.5]octane (2.44%), 1,5,5,8-Tetramethyl-12-oxabicyclo[9.1.0]dodeca-3,7-diene (1.96%), Sabinen (1.79%), D-Limonene (1.39%), α-Cadinol(1.20%). © All Rights Reserved.

Background: This study was subjected to investigate different pharmacological properties of ethanol extract of Solena amplexicaulis root. Results: The extract contains flavonoid, alkaloid, saponin and steroid compounds. The extract exhibited excellent antioxidant activity in DPPH radical scavenging activity. The extract also showed potent activity in brine shrimp lethality bioassay. The LC50 value was found to 44.677 μg/ml. The extract showed better anti-bacterial activity against gram-negative bacteria. In antifungal assay, the maximum 79.31% of anti-mycotic activity was observed against Aspergillus ochraceus while minimum 44.2% against Rhizopus oryzae. MIC value ranged between 1500-3000 μg/ml. The extract was found moderately toxic with a 24-hr LD50 value of 81.47 mg/kg in Swiss albino mice. The degree of inhibition by the ethanolic extract of the root was found less than that of standard analgesic drug diclofenac sodium. The extract also showed moderate anti-inflammatory and antinociceptive activity and anti-diabetic property. Reducing power of the extract was comparable with standard ascorbic acid. Moderate in vitro thrombolytic activity, lipid peroxidation inhibition property, metal chelating ability and stress-protective activity was also observed. Conclusion: Ethanol extract of Solena amplexicaulis root can be valuable for treatment of different diseases. © 2014 Kabir et al.
