Chemical composition of four different species of the Waltheria genus
This study aimed the phytochemical investigation of four different species of the genus Waltheria (W. douradinha, W. ferruginea, W. indica and W. cinerencens), collected in the Northeast of Brazil. Different species of the genus previously studied showed the presence of flavonoids and alkaloids as major constituents, being compatible with this study, that led to the isolation of eight substances, two lupan-type triterpenes: betulonic (3) and betulinic acid (4), five flavonoids: 5-hydroxy-3, 3′, 4′, 7-tetra-methoxy-flavone (retusine, 1), 5-hydroxy-3, 4′, 7-tetramethoxy-flavone (2), kaempferol-3-O-β- (...

Chemical constituents from Nannoglottis yuennanensis
Publication date: October 2018Source: Biochemical Systematics and Ecology, Volume 80Author(s): Yi Yu, Yang Song, Li Liu, Qiang Sun, Honglei ZhouAbstractSixteen reported compounds (1–16), including two sterols, nine triterpenes and five phenylpropanoids, were obtained from Nannoglottis yuennanensis (Compositae) by chromatographic methods. Their structures were confirmed on the basis of spectroscopic methods. Among them, five compounds were firstly reported from the genus Nannoglottis, while others were obtained from this species for the first time. In addition, this study indicated that genus Nannoglottis could be div...

Phytochemistry of the genus impatiens (Balsaminaceae): A review
Publication date: October 2018Source: Biochemical Systematics and Ecology, Volume 80Author(s): Katarzyna SzewczykAbstractThe genus Impatiens L. belongs to the Balsaminaceae family and includes more than 480 accepted species. This genus grows in tropical and subtropical regions, mostly in tropical Africa, India, southwestern part of Asia, and southern China. Various phytochemical studies have been conducted; however, there are no recent reports that provide a comprehensive summary of the phytochemistry of Impatiens L. The review summarizes literature data on chemical components identified in the species of Impatiens L. The ...

Chemotaxonomic potential of exocrine alkyl esters in julid millipedes (Diplopoda: Julidae: Cylindroiulini)
Publication date: December 2018Source: Biochemical Systematics and Ecology, Volume 81Author(s): Michaela Bodner, Boyan Vagalinski, Günther RaspotnigAbstractThere are numerous chemotaxonomic studies on arthropods, but such are largely missing for millipedes. This appears curious since particularly in millipedes, the major taxa are clearly distinctive by different exocrine products, such as alkaloids (Glomerida), terpenoids (Polyzoniida), phenolics and cyanogens (Polydesmida), and benzoquinones (Juliformia). However, there is low within-taxon variation of the chemicals mentioned which - in almost invariable blends - cha...
