Selective recovery of tropane alkaloids applying liquid membrane technique [PDF]

open access: yes, 2006
A tropine recovery from its solutions applying a liquid membrane technique was studied. Among several studied organic solvents, chloroform showed best extraction ability towards atropine.

Report on the 2016 Proficiency Test of the European Union Reference Laboratory for Mycotoxins for the Network of National Reference Laboratories: Determination of tropane alkaloids in tea and herbal infusions [PDF]

open access: yes, 2017
Tropane alkaloids (TAs) are toxins found in a wide variety of plant species growing in mild climates. The most well-known are Datura, Atropa and Hyoscyamus sp., belonging to the Solanaceae family.

Calystegine degradation capacities of microbial rhizosphere communities of Zea mays (calystegine-negative) and Calystegia sepium (calystegine-positive) [PDF]

open access: yes, 2017
Calystegines are tropane alkaloids produced by the roots of a few plant species. A bioassay was developed to identify roots with a microbial rhizosphere community capable of calystegine degradation (i.e. MCD roots).

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research

open access: yesMass Spectrometry Reviews, Volume 45, Issue 2, Page 429-452, March/April 2026.
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

The study of hyoscyamine in oxidative stress of liver cells in male rat [PDF]

open access: yes, 2017
Background and aims: Increased production of free radicals by endogenous systems and exogenous sources in cells leads to oxidative stress, which damages to the cells of various organs.

Demystifying fungal systematics: A gateway to fungal literacy and societal/ecological relevance through familiar species

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 2, Page 499-515, March 2026.
Fungal systematics can feel overwhelming given the vast species diversity within this kingdom, with numerous subgroups at every taxonomic rank. This often creates a disconnect between the undertsnidng of fungal taxonomic diversity and their societal relevance.

Review on New Techniques in Tropane Alkaloids Production

open access: yesJournal of Medicinal Plants, 2010
Increasing from day to day tendency of human societies to plant based drug usage increased demand of secondary metabolite application. Although artificial production of these compounds greatly progressed, but the only way to achieve these fine medicinal ...

RrMYB2 Regulates Drought Stress via RrJMJ12‐Dependent Epigenetic Modification in Rosa rugosa

open access: yesPlant Biotechnology Journal, Volume 24, Issue 3, Page 1578-1594, March 2026.
ABSTRACT Rosa rugosa (R. rugosa), an economically important crop valued for its fragrance and medicinal properties, is highly susceptible to drought stress under open‐field cultivation. However, the molecular mechanisms underlying its drought response remain largely unexplored.

Tropane Alkaloids: Chemistry, Pharmacology, Biosynthesis and Production [PDF]

open access: yesMolecules, 2019
Tropane alkaloids (TA) are valuable secondary plant metabolites which are mostly found in high concentrations in the Solanaceae and Erythroxylaceae families. The TAs, which are characterized by their unique bicyclic tropane ring system, can be divided into three major groups: hyoscyamine and scopolamine, cocaine and calystegines.

From MS1 to Structure: A Van Krevelen–DBE–Aromaticity‐Based Framework for Annotating Specialized Metabolites via High‐Resolution Mass Spectrometry

open access: yesRapid Communications in Mass Spectrometry, Volume 39, Issue 24, 30 December 2025.
ABSTRACT Rationale Classifying specialized metabolites in untargeted metabolomics remains a major challenge, particularly when relying solely on high‐resolution mass spectrometry (HRMS) data at the MS1 level. Traditional approaches using Van Krevelen diagrams often lack sufficient resolution to distinguish structurally similar metabolite classes ...
