The objective of this work was to produce, through the thermoplastic extrusion process followed by blowing, manioc starch-based flexible films added with Brazilian pepper oil as an antioxidant and plasticizer agent, and verify if the bioactive compounds contained in the fresh pepper oil are present after the drying step of the thermoplastic extrusion. After analysis by gas chromatography-mass spectrometry volatiles compounds were identified in the films. Pepper oil also  influenced the mechanichal properties of the films.These results suggest that the temperatures used in the process, kept some of the existing compounds in the Brazilian pepper essential oil adhered to the packages. Keywords: Termoplastic extrusion, temperature, bioactivs compounds

 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.

The present study aimed to analyze the chemical composition of the essential oil from Garcinia gardneriana (Planchon & Triana) Zappi leaves and fruits, and to determine its acaricidal activity on Rhipicephalus microplus by larval packet test and larvicidal action on Aedes aegypti by larval immersion test. The chemical analysis of the essential oil by gas chromatography-mass spectrometry identified sesquiterpene hydrocarbons and oxygenated sesquiterpenes in bacupari leaves and fruits, and α-cedrene, α-chamigrene, α-trans-bergamotene, and β-curcumene as major compounds. Essential oil from leaves of G. gardneriana presented acaricidal activity on R. microplus (LC50 = 4.8 mg/mL; LC99 = 10.8 mg/mL) and larvicidal effect on A. aegypti (LC50 = 5.4 mg/mL; LC99 = 11.6 mg/mL), whereas essential oil from the fruits of G. gardneriana showed LC50 = 4.6 mg/mL and LC99 = 8.9 mg/mL against R. microplus and LC50 = 6.4 mg/mL and LC99 = 13.9 mg/mL against A. aegypti. These results thus demonstrate the potential acaricidal and larvicidal activity of essential oil of G. gardneriana, offering new perspectives for the realization of bioassays from this essential oil.

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.

Rhamnus caroliniana (Rhamnaceae), or Carolina buckthorn, is a plant commonly found in the southeastern United States that was used in Cherokee traditional medicine. To date, there have been no reports on the phytochemical constituents of R. caroliniana. The bark of R. caroliniana was collected and extracted with chloroform. The crude chloroform extract was subjected to preparative column chromatography on silica gel leading to the isolation of two anthraquinones (chrysophanol and physcion), the bianthrone ararobinol, the dihydroxynaphthalene torachrysone, and the fatty alcohol 1-docosanol. The bark essential oil of R. caroliniana was obtained by hydrodistillation and analyzed by gas chromatography – mass spectrometry. The major bark volatiles were the anthrone chrysarobin (24.2%), the piperidine alkaloid piperine (15.4%), and the dibenzoxepin pacharin (7.5%).
