Intra- and interpopulation variability of Balkan endemic - Satureja kitaibelii based on n-alkane profile
Publication date: August 2019Source: Biochemical Systematics and Ecology, Volume 85Author(s): Tanja Dodoš, Nemanja Rajčević, Pedja Janaćković, Jelica Novaković, Petar D. MarinAbstractSatureja kitaibelii Wierzb. ex Heuff. is endemic species of central Balkan that lives along the Balkan mountains range. The aim of this research was to study the variability of n-alkane profiles of four S. kitaibelii populations growing wild in Serbia in regards to biogeography and chemotaxonomy. Using GC/MS and GC/FID, seventeen n-alkane homologues (C19–C35) were identified. n-Hentriacontane (C31) was dominant in all populat...

Phytochemical and chemotaxonomic study on Fallopia aubertii (L. Henry) Holub
Publication date: August 2019Source: Biochemical Systematics and Ecology, Volume 85Author(s): Jinfeng Wang, Gaixia Ma, Jinzhong HuAbstractTwenty reported compounds (1–20), including four sterols, five triterpenes, two anthraquinones, three chromones, two stilbenes and four flavonoids, were obtained from Fallopia aubertii by phytochemical methods. Their structures were confirmed on the basis of spectroscopic methods. Among them, nine compounds were firstly reported from the genus Fallopia, while eight of them were obtained from this species for the first time. In addition, this study discussed the relatonships between...

Chemical composition of floral scents from three Plumeria rubra L. (Apocynaceae) forms linked to petal color proprieties
Publication date: August 2019Source: Biochemical Systematics and Ecology, Volume 85Author(s): Wei-Chang Gong, Shi-Juan Xu, Yan-Hong Liu, Chuan-Ming Wang, Konrad Martin, Ling-Zeng MengAbstractThe floral scents of three forms of cultivated Plumeria rubra L. were evaluated through mass flowering phenology using the dynamic headspace adsorption method and were identified with coupled gas chromatography and mass spectrometry. The forms P. rubra f. acutifolia and P. rubra f. lutea had white and yellow flower petals, respectively, and the flower petals of P. rubra f. rubra were red. Although 68 components of the flower scents of ...

Identification of anthocyanins in the corona of two species of Passiflora and their hybrid by ultra-high performance chromatography with electrospray ionization tandem mass spectrometry (UHPLC-ESI-MS/MS)
Publication date: August 2019Source: Biochemical Systematics and Ecology, Volume 85Author(s): Lilian Cristina Baldon Aizza, Alexandra Christine Helena Frankland Sawaya, Marcelo Carnier DornelasAbstractPlants belonging to the genus Passiflora produce exuberant flowers with characteristic corona filaments that vary widely in size, morphology and color. This variability is thought to be an adaptation to different animal pollinators. In general, Passiflora flowers are pollinated by bees, hummingbirds and bats. The aim of this study was to identify the anthocyanins present in the corona filaments of two wild parent species, P. ...
