In the present study, anti-IBV (infectious bronchitis virus) activities of (-)-pinenes were studied by MTT assay, as well as docking and molecular dynamic (MD) simulations. The CC₅₀ values of (-)-α-pinene and (-)-β-pinene were above 10 mM. And the maximum noncytotoxic concentrations (TD₀) of (-)-α-pinene and (-)-β-pinene were determined as 7.88 ± 0.06 and 6.09 ± 0.31 mM, respectively. The two c...

BACKGROUND α-Pinene is an important natural product that is widely used in flavorings, fragrances, medicines, fine chemicals and high-density renewable fuels. Currently, α-Pinene used in industry is mainly produced either by tapping trees (gum turpentine) or as a byproduct of paper pulping (crude sulfate turpentine, CST). However, the extraction of it from trees is tedious and inefficient and r...

The objective of the present study was to characterize essential oil Myrciaria tenella (MTEO) leaves, determine effects distillation time (1 5 h), and evaluate its action on acute pain inflammation both in vivo vitro. MTEO obtained by hydrodistillation for 4 h 36 compounds were detected, mainly consisting hydrocarbon terpenes such as β-pinene (21.46%), α-pinene (19.43%), E-caryophyllene (10.89%...

The transition of grasslands to shrubdominated scrubland reduces livestock productivity and contributes to impoverished conditions for humans in arid and semiarid regions worldwide. Many shrubs that are increasing in dominance contain secondary compounds that deter browsing by herbivores. Knowledge concerning the effects of specific compounds in herbivore diets is limited but may provide useful...

Inhalation therapy using essential oils has been used to treat acute and chronic sinusitis and bronchitis. The aim of the present study was to determine the chemical composition of the essential oil of Artemisia capillaris, and evaluate the antibacterial effects of the essential oil and its main components, against common clinically relevant respiratory bacterial pathogens. Gas chromatography a...

Background:Tanacetum vulgare L. (Asteraceae) is a perennial herb that has been used to treat multiple ailments. Regional variability of the chemical composition of T. vulgare essential oils is well-known. Despite these regional chemotypes, most relevant studies did not analyze the complete chemical composition of the T. vulgare essential oil and its constituents in relation to their biological ...

Secondary organic aerosol (SOA) formation from photooxidation of α-pinene has been investigated in a photochemical reaction chamber under varied inorganic seed particle acidity levels at moderate relative humidity. The effect of particle acidity on SOA yield and chemical composition was examined under highand low-NOx conditions. The SOA yield (4.2–7.6 %) increased nearly linearly with the incre...

  Background: The genus Eucalyptus (family Myrtaceae) comprises well-known plants of over 600 species of trees. Although most of the plants are native to Australia, numerous species have been introduced to other parts of the world, including Iran, as economic and ornamental trees in forest trial provenances, where the plants have become source of important fast-growing hardwood trees and Eucaly...

The present study describes radical scavenging capacity (RSC), antimutagenic and antibacterial properties of the essential oil (EO) of the leaves of Eucalyptus gunnii Hook. (Southern Montenegro). Chemical composition was evaluated by gas chromatography-mass spectrometry (GC-MS). In oil, 1,8-cineole (67.8%) and α-pinene (14.12%) were the major compounds comprising almost 82% of total EO. EO exhi...

Studies involving the consumption,metabolism, and elimination of terpenes by small ruminants consuming terpene-laden shrubs as well as those exploring the potential for natural products as rumen modifiers could benefit from a procedure that measures terpenes in both blood and rumen fluid and that is suitable for either serum or plasma. The objective of this study was to modify an existing proce...
