In vitro androgenetic cultures of Hyoscyamus niger L., H. albus L. and alkaloid content assay
Acta Societatis Botanicorum Poloniae, 2014 In vitro cultures of Hyoscyamus niger L. and H. albus L. anthers were initiated which resulted in obtaining androgenectic plants and callus cultures. The leaves of these pants and the callus cultures were subjected to analysis (TLC, GC for the presence ...

Nature Communications, 2023 Tropane alkaloids (TAs) are synthesized by some species in Solanaceae. Here, the authors assemble the genomes of two representative TAs producing species, show that gene loss shapes uneven distribution of TAs in Solanaceae, and identify a cytochrome P450

ChemistryOpen, Volume 15, Issue 8, August 2026.Low‐molecular‐weight phenolic acids in M. autumnalis were associated with antioxidant activity, AChE, and hCA inhibition effects, whereas flavonoid‐rich S. junceum displayed BChE‐oriented inhibition effect and antibacterial activity. LC‐MS/MS‐based metabolite profiling linked distinct chemical compositions to bioactivity patterns, supporting further ...

Parallel modification of tropane alkaloids
, 2001 Various tropane alkaloids have been prepared by structural modification of the readily available natural product, scopolamine 1. Reaction of isocyanates with 6,7-dehydrotropine 5 provided a number of urethanes 6a-e. Reductive amination of tropinone 7 and

Plant Biotechnology Journal, Volume 24, Issue 8, Page 4823-4843, August 2026.ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

Food Frontiers, Volume 7, Issue 4, July 2026.This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...
