Chemical diversity of accessions of the in vivo germplasm bank of Varronia curassavica (Jacq.) Agronomy
Queiroz, Túlio Barroso; Fonseca, Francine Souza Alves da; Mendes, Aretusa Daniela Resende; Azevedo, Alcinei Mistico; Martins, Ernane Ronie.
Varronia curassavica (Jacq.) is a shrub and perennial plant native to Brazil that has therapeutic, anti-inflammatory and cicatrizing properties. The objective of this work was to study the chemical diversity of the native populations of this species maintained in the in vivo germplasm bank from Montes Claros, Minas Gerais, Brazil. The essential oils of 10 accessions analyzed in triplicate were obtained by hydrodistillation. Fifty-five compounds were detected, 46 of which were identified by GC-MS analysis. Essential oil yield ranged from 0.1 (VC-9) to 1.22% (VC-3) among the studied accessions. Three groups were formed by cluster analysis. Group A presented lower relative abundance of the compounds α-humulene (1.4%) and β-caryophyllene (8.5%). Conversely, in...

Métoyer, Benjamin; Lebouvier, Nicolas; Hnawia, Edouard; Thouvenot, Louis; Wang, Fengrui; Harinantenaina Rakotondraibe, Liva; Raharivelomanana, Phila; Asakawa, Yoshinori; Nour, Mohammed.
The first chemotaxonomic study based on volatile components of Porella viridissima (Mitt.) Grolle is reported. The GC-MS analysis of ether extract was performed; ten santalane and five pinguisane-type sesquiterpenes were identified together with perrottetianal A as major diterpene. Most of detected santalane-type sesquiterpenes are reported for the first time in liverwort. P. viridissima was found to belong to the chemotype III (pinguisane/sacculatane) and shared chemical similarities with P. navicularis. Perrotettianal A was isolated and has shown strong cytotoxicity against ovarian cancer.
