Phenolic variation among Chamaecrista nictitans subspecies and varieties revealed through UPLC-ESI(-)-MS/MS chemical fingerprinting
(2019-01-19)
Introduction
Comparative analysis of metabolic features of plants has a high potential for determination of quality control of active ingredients, ecological or chemotaxonomic purposes. Specifically, the development of ...
Fingerprinting of cerrado species based on cork lipophilic constituents
(Elsevier B.V., 2020-02-01)
Cerrado is a savanna ecosystem of central and southeastern Brazil. Many woody species of cerrado have thick layers of cork. The present work aimed to characterize, by GC/MS analysis, the constituents of n-hexane extracts ...
