Viburnum tinus L.: Investigation on its spontaneous emission at different phenological stages
Publication date: April 2020Source: Biochemical Systematics and Ecology, Volume 89Author(s): Basma Najar, Benedetta Ferri, Pier Luigi Cioni, Luisa PistelliThe volatile components emitted from different organs of Viburnum tinus L., collected during various developmental stages, were analysed by solid phase micro extraction (SPME) and identified by GC-MS. More than 90% of the identified fraction was represented by non-terpenes in both young and adult leaves (94.2% and 94.3%, respectively), as well as in fruits of different ages: unripe and ripe (red and black) (93.1%, 90.6% and 90.9%, respectively). This latter class was als...

Geographical and seasonal variation in water hemlock (Cicuta maculata) toxins
The objective of this study was to evaluate the variation in cicutoxin and total C17 polyacetylene compounds in water hemlock populations across western North America. Cicutoxin and total C17 polyacetylene concentrations varied among the six collection locations and among plant parts. Tubers contained the highest cicutoxin and total C17 polyacetylene concentrations of all plant parts. Green seeds contained the second most abundant total C17 polyacetylene concentrations. Total C17 polyacetylene and cicutoxin concentrations were also compared in different plant parts at several different phenological stages over the growing ...

Grayanane diterpenoids from the leaves of Rhododendron dauricum
Publication date: April 2020Source: Biochemical Systematics and Ecology, Volume 89Author(s): Xiang Peng, Hanqi Zhang, Xinghua Yuan, Zibo Chen, Jinbo Gao, Yang Teng, Guangmin YaoAbstractPhytochemical investigations on the leaves of Rhododendron dauricum L. (Ericaceae) resulted in the isolation of thirteen known grayanane diterpenoids (1–13). Their structures were determined by spectroscopic data analysis and comparison with the literature. The structure and absolute configuration of grayanotoxin VI (1) was determined by single-crystal X-ray diffraction analysis for the first time. This is the first time to report the isol...

Epicuticular wax variability of Juniperus deltoides R.P. Adams from the central Balkan – Ecology and chemophenetics
Publication date: April 2020Source: Biochemical Systematics and Ecology, Volume 89Author(s): Nemanja Rajčević, Tanja Dodoš, Jelica Novaković, Pedja Janaćković, Petar D. MarinAbstractJuniperus deltoides R.P.Adams is a prickly, evergreen shrub that grows in the East Mediterranean on dry hills and mountains. Needle-like leaves have a thick cuticular layer on the surface, which serves as the ultimate barrier for prevention of water loss. n-Alkanes comprise the biggest part of this hydrophobic wax mixture. These compounds are studied as chemophenetic characters due to their chemical and physiological stability, and strong...
