Chemical Ecology and Volatile Terpenes Biosynthesis of Arnicas-da-Serra from Brazil
(Brazilian Chemical Soc, 2016-01-01)
Lychnophora (Vernonieae: Asteraceae) is a genus endemic to campos rupestres, which are fragile Habitats from Brazilian Savanas, the Cerrado. Leaves extracts of Lychnophora ericoides (Arnica-da-serra) are commonly used as ...
Allelopathic potential of Tagetes minuta terpenes by a chemical, anatomical and phytotoxic approach
(Elsevier, 2008-12)
The dominant terpenes in the essential oils of the leaves and reproductive structures of Tagetes minuta L. (Asteraceae) were studied throughout its life cycle in a natural population. The anatomy of the secretory cavities ...
A genomic approach to characterization of the Citrus terpene synthase gene family
(Sociedade Brasileira de Genética, 2007)
Volatile emissions of scented Alstroemeria genotypes are dominated by terpenes, and a myrcene synthase gene is highly expressed in scented Alstroemeria flowers
(2012)
Native to South America, Alstroemeria flowers are known for their colourful tepals, and Alstroemeria hybrids are an important cut flower. However, in common with many commercial cut flowers, virtually all the commercial ...
The chemical reactivity of some terpenes investigated by alumina catalyzed epoxidation with hydrogen peroxide and by DFT calculations
(Elsevier Science BvAmsterdamHolanda, 2006)
Allium sativum produces terpenes with fungistatic properties in response to infection with Sclerotium cepivorum
(Elsevier, 2015-07-26)
This study investigated terpene biosynthesis in different tissues (root, protobulb, leaf sheath and blade) of in vitro-grown garlic plants either infected or not (control) with Sclerotium cepivorum, the causative agent of ...
Antimicrobial combined action of terpenes against the food-borne microorganisms Escherichia coli, Staphylococcus aureus and Bacillus cereus
(Wiley, 2009-09)
The aims of this work were to study the antimicrobial activity of nine monoterpenes and the synergistic or antagonistic associations between them, and to relate water solubility, H-bonding and pKa values with antimicrobial ...
Dry and wet seasons set the phytochemical profile of the Copaifera langsdorffii Desf. essential oils
(Taylor & Francis Inc, 2014-08-01)
Dry and wet seasons present in different formations on the Cerrado domain are capable of promoting alterations in the composition of volatile compounds (terpenes) in the essential oil from copaiba (Copaifera langsdorffi ...
Chemical composition of essential oils from the vegetative and reproductive structures of Copaifera langsdorffii Desf
(Taylor &francis Ltd, 2015-05-03)
GC/FID and GC-MS analysis revealed germacrene D, bicyclogermacrene, alpha-cadinol and cubenol as major compounds from aril. Germacrene D, bicyclogermacrene, trans-caryophyllene and delta-elemene are major compounds in ...
