The isolation and structure of 6"-bromo-isoarboreol - the first bromine containing lignan
A new lignan from Gmelina arborea is shown to be 1, 2a-dihydroxy-2e-piperonyl-6e-(6"-bromopiperonyl)-3, 7-dioxabicyclo-[3,3,0]-octane, the first example of a bromine containing ...

The synthesis of lignans and lignan analogs
In this thesis 'E,E'-dibenzylidenesuccinates were shown to exhibit atropisomerism, enantiomerism that originates from hindered rotation about the butadiene carbon - carbon single bond. In addition, the 'E,E'-dibenzylidenesuccinates were found to undergo photochemical electrocyclic reactions and thermal 1,5-sigmatropic hydrogen shifts to give 'cis'-1,2 ...

Serial‐passage testing in wound‐relevant bacteria showed that Norway spruce (Picea abies) resin did not produce confirmed resistance development under the conditions tested. These findings support spruce resin as a natural antimicrobial with low propensity to select resistance.

Polyphenol‐Rich Foods as a Healthy and Sustainable Strategy: Mental Health and Metabolomic Profiling
A 12‐week nutritional intervention with cocoa flavanols and red‐berry anthocyanins in older adults improved emotional well‐being and identified metabolomic signatures associated with the intervention through urinary metabolome profiling. ABSTRACT The so‑called demographic transition has increased the prevalence of chronic diseases in adults over 65 ...

An antiplasmodial lignan from Euterpe precatoria
As a part of a study on new antiplasmodial natural products, a new 8-5′ linked lignan dehydrodiconiferyl dibenzoate (2) and p-hydroxybenzoic acid (1) were isolated from the roots of the palm Euterpe precatoria.

ABSTRACT Sesame (Sesamum indicum L., 2n = 26) is one of the oldest oilseed crops and is often called the ‘queen of oilseeds’ due to its high content of unsaturated fatty acids and natural antioxidants. Despite its long history, the origin and global spread of cultivated sesame remain unresolved.
