The objective of this study was analysis of the secondary metabolite products. Bioactives are chemical compounds often referred to as secondary metabolites. Sixteenth bioactive compounds were identified in the methanolic extract of Mentha pulegium. The identification of bioactive chemical compounds is based on the peak area, retention time molecular weight and molecular formula. GC-MS analysis of Mentha pulegium revealed the existence of the Erythritol , Cyclohexanone , 3-methyl-,(R)- , 2,4-Dihydroxy-2,5-dimethyl-3(2H)-furan-3-one , 1-Oxaspiro[2.5]octan-4-one ,2,2,6-trimethyl-, cis- , Terpinyl formate , Acetamide , N-methyl-N-[4-(3-hydroxypyrrolidinyl)-2-butynyl]- , Pulegone , 2-Oxabicyclo[3.3.0]oct-7-en-3-one , 7-(1-hydroxypentyl)- , 2(3H)-Naphthalenone ,4,4a,5,6,7,8-hexahydro-1-methoxy- , 2-Cyclopenten-1-one , 2-(2-butenyl)-4-hydroxy-3-methyl-,(Z)- , (5β)Pregnane-3,20β-diol 14α,18α-[4-methyl-3-oxo-(1-oxa-4- , 2-(4-(But-2-yl)phenyl) propnoic acid , Nootkaton-11,12-epoxide , 2-Heptanone , 6-methyl-6-[3-methyl-3-(1-methylethenyl)-1-cyclo , Cholestan-3-ol , 2-methylene-, (3β,5α)- , 1-Heptatriacotanol and Digitoxin.

Objective: This study is designed to hunt for the presence of bioactive compounds from three marine sponges collected from Kovalam.Methods: Zoochemical analysis is performed to screen for the presence of secondary metabolites. Based on those results, only two sponges which showed a significant presence of secondary metabolites has been subjected to gas chromatography-mass spectrometry (GC-MS) analysis to identify the unknown chemical compounds present in those sponges.Results: On analyzing the results, two sponges, namely, Dysidea herbacea and Sigmadocia pumila, has shown a significant presence of secondary metabolites while the third sponge Acanthella elongata have shown moderate presence of secondary metabolites. Since the first two sponges results are remarkable, these two samples have been subjected to GC-MS analysis to separate and identify the unknown chemical compounds present in the sample.Conclusion: Samples, namely, D. herbacea and S. pumila, indicated the presence of several components. From both the sponges, eleven different secondary metabolites were identified by GC-MS. Most of these compounds are widely used in cosmetic, pharmaceutical, and other industries and therefore a vital source for industrial biotechnology and related products in healthcare and skincare.Keywords: Dysidea herbacea, Sigmadocia pumila, Acanthella elongata, Secondary metabolites, Gas chromatography-mass spectrometry analysis, Bioactive compounds.

Background: Conium maculatum is known as highly toxic plant, due to piperidine alkaloids present in the aerial parts. In a first attempt, in various tap root samples, however, alkaloids could not be detected. The present study describes active compounds in the tap roots from 16 populations harvested at maturity. The compounds were extracted with dichloromethane from root pieces of single plants and analyzed by gas chromatography–mass spectrometry. Ten bioactive compounds were evaluated: five furocoumarins, two prenylated coumarins, two aliphatic C17-polyacetylenes and the phenylpropanoid elemicin. A high variability could be observed, the highest concentrations were measured for falcarindiol, xanthotoxin and isopimpinellin, the lowest for elemicin. In sum C. maculatum roots contained comparable amounts of compounds that are characteristic for Apiaceae, and also occur in vegetables as carrots, parsnip, parsley or celeriac.

Entomopathogenic nematodes (EPNs) are known to be highly pathogenic to insect pests, due to their associated symbiotic bacteria, which produce virulence factors, exo-enzymes and other harmful secondary metabolites to conquer, kill, and degrade their insect hosts. However, these properties are not fully characterized. This study reports on the antimicrobial activities of Photorhabdus sp. strain ETL, symbiotically associated to an insect pathogenic nematode, Heterorhabditis zealandica, against human pathogenic bacteria and toxigenic fungi, as well as the non-targeted profiling of its secondary metabolites (SMs) using gas chromatography coupled to high-resolution time-of-flight mass spectrometry. Fatty acids including 3-eicosene, (E)-; 5-eicosene, (E)-; eicosene; 9-octadecenamide; undecanoic acid with shown antimicrobial activities were detected. This provided more insight on the composition and bioactivities of SMs produced by the Photorhabdus sp.

 Objective:The objective of this study is to characterize the phytoconstituents of Tiliacora racemosa Colebr. using gas chromatography mass spectrometry (GC-MS).Methods: Preliminary phytochemical and physicochemical analysis was carried out using standard procedures. GC-MS analysis of methanolic extract was carried out using Thermo GC-Trace Ultra version: 5.0, Thermo MS DSQ with a DB 35MS capillary standard non-polar column and gas chromatograph interfaced to a mass selective detector (MS DSQ II) with Xcalibur software.Results: Preliminary phytochemical screening revealed the presence of alkaloids, flavonoids, phenols, tannins, triterpenoids, steroids, proteins and amino acids, carbohydrates, saponins and coumarin. Quinones, anthraquinones, glycosides and fixed oil were absent. GC-MS analysis revealed the presence of 28 compounds of which quinic acid (retention times [RT]: 15.65) and inositol, 1-deoxy-(CAS) (RT: 19.24) was observed as abundant compounds.Conclusion: The presence of various bioactive compounds confirms the medicinal importance and it’s application for curing various diseases by traditional practitioners. However, isolation and characterization of potential bioactive compounds would lead to drug formulation.

Toxic normal hydrocarbon (NH), nonadecane in the methanolic extract of the whole of cabbage samples collected from different districts of Bangladesh was analyzed by GC-MS. It was observed that NH deposition on the samples takes place in different morphological parts of the biological materials. The NH, nonadecane, was found in the cabbage samples collected from the highway road side by the extraction of methanol. The identification and quantification of the title compounds have not been reported previously in the cabbage sample.   Keywords: Cabbage; brassica oleracea var. capitata f. alba; quantification; normal hydrocarbon, nonadecane, GC-MS
