Phytochemical composition and cultivar‐dependent variation in colored lettuce (Lactuca sativa) and their α‐amylase inhibitory activity

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND This study investigated cultivar‐dependent variation in the phytochemical composition of lettuce (Lactuca sativa) using liquid chromatography–tandem mass spectrometry (LC–MS/MS) profiling and high‐performance liquid chromatography (HPLC) quantification, with a focus on enzyme inhibitory activity. RESULTS Significant differences were

Unveiling chemical composition of peppermint oil and its bioactivities compared with (R)‐(+)‐limonene: antimicrobial, antibiofilm, and insecticidal perspectives

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Peppermint (Mentha piperita L.) essential oil (MPEO) is recognized for its broad‐spectrum antimicrobial properties and potential applications in food preservation. This study aimed to determine whether the bioactivity of MPEO is attributable to (R)‐(+)‐limonene or whether the complete essential oil provides higher efficacy due to ...

Alkaloids and Sesquiterpenes from the South China Sea Gorgonian Echinogorgia pseudossapo

open access: yesMarine Drugs, 2011
Five zoanthoxanthin alkaloids (1–5) and four sesquiterpenes (6–9) were isolated from the South China Sea gorgonian Echinogorgia pseudossapo. Their structures were determined on the bases of extensive spectroscopic analyses, including 1D and 2D NMR data ...

Influence of crosslinker on the properties of terpene‐based poly(high internal phase emulsion)s

open access: yesPolymer International, EarlyView.
Myrcene was polymerized and crosslinked with hydrophilic monomeric and oligomeric dimethacrylates within high internal phase emulsions to produce hierarchically porous bio‐based poly(high internal phase emulsion)s with tuned morphology and mechanical properties.

Kinetics of anionic polymerization of β‐myrcene in hydrocarbon solvents

open access: yesPolymer International, EarlyView.
The process of anionic polymerization of β‐myrcene in hydrocarbon solvents was examined by kinetic studies and quantum chemical calculations. Abstract The kinetics of anionic polymerization of β‐myrcene initiated by sec‐butyllithium were examined in saturated and unsaturated hydrocarbon solvents, i.e. cyclohexane, cyclohexene, 4‐vinylcyclohexene and dl‐

Unsaturated biobased polyesters from bicyclic α‐pinene‐based diols

open access: yesPolymer International, EarlyView.
We present the synthesis of four biosourced unsaturated polyesters made from chiral terpene‐based diols and esters of renewable diacids. The resulting materials harbor a bicyclic pinene ring in their backbones which leads to enhanced thermal properties while still conferring susceptibility to enzyme hydrolysis for chains having a cis alkene.
