Seasonal Fluctuations of Plastochromanol‐8 and α‐Tocopherol Amounts in the Leaves of Cecropia Trees

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Plastochromanol‐8 (PC‐8) is a homologue of γ‐tocotrienol with a longer side chain (eight instead of three isoprene units) and therefore also a representative of the tocochromanol (vitamin E) group. PC‐8 has been determined in various plants and seeds, with Cecropia sp. leaves showing unusually high levels.

Comparative Profiles of Lipophilic Nutrients and In Vitro Antioxidant Activity in Commercial Arabica and Robusta Green Coffee Beans

Journal of the American Oil Chemists' Society, EarlyView.
Integrated compositional profiling of ten commercial green coffee lots showed higher mean total phenolic content, DPPH radical‐scavenging activity, β‐carotene, and total phytosterols in Robusta‐labeled lots, whereas Arabica‐labeled lots showed higher mean total tocopherols and total measured fatty acids.

refloraR: An R package for efficiently retrieving and analyzing plant specimen data from the Herbário Virtual Reflora

Applications in Plant Sciences, EarlyView.
Abstract Premise Advances in the digitization of herbarium collections are enabling open access to specimen data for research and conservation. In Brazil, the Herbário Virtual Reflora (HVR) hosts over 4.8 million high‐resolution images of botanical specimens and their associated data from 86 national and international herbaria.

Herbarium‐based measurements are reliable predictors of fresh plant traits in Neotropical Myrtaceae

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens are increasingly used to extract morphological traits for ecological and evolutionary studies, yet the effects of tissue desiccation on trait measurements remain poorly understood. Here, we tested two hypotheses: (H1) whether higher tissue water content leads to greater measurement changes after herborization and ...

Petal to the metal: The slow road to automating large‐scale phenology labeling for herbarium specimens

Applications in Plant Sciences, EarlyView.
Abstract Premise Herbarium specimens represent critical historical records of plant phenology, yet automating annotation of reproductive structures remains challenging given the diversity of floral morphologies, specimen age and quality, and image quality.
