Procedures to evaluate potential of plants as natural food preservatives: Phytochemical characterization, novel extraction technology, and safety evaluation—A comprehensive review

Food Science &Nutrition, Volume 12, Issue 9, Page 6142-6156, September 2024.
The use of plant extracts and EOs as preservatives in food products is a growing trend. Artemisia revealed good antimicrobial and antioxidant effects. Artemisia can be a novel natural agent for food preservation. The recent developments in extraction of Artemisia are discussed.

Laccase-catalyzed coupling of catharanthine and vindoline : an efficient approach to the bisindole alkaloid anhydrovinblastine

, 2009
The efficient enzyme-catalyzed coupling of the indolic alkaloids catharanthine and vindoline was carried out by exploiting the oxidoreductases laccases and atmospheric oxygen.

Integration of cell differentiation and initiation of monoterpenoid indole alkaloid metabolism in seed germination of Catharanthus roseus

New Phytologist, Volume 242, Issue 3, Page 1156-1171, May 2024.
Summary In Catharanthus roseus, monoterpenoid indole alkaloids (MIAs) are produced through the cooperation of four cell types, with final products accumulating in specialized cells known as idioblasts and laticifers. To explore the relationship between cellular differentiation and cell type‐specific MIA metabolism, we analyzed the expression of MIA ...

Structure and Synthesis of Vindolicine and Derivatives

Chemistry &Biodiversity, Volume 21, Issue 4, April 2024.
Abstract This article describes the reaction of vindoline with formaldehyde and trimethyl orthoformate to prepare vindolicine, tris‐vindolicinyl methane and higher molecular weight homologues. The synthesis of 10‐formyl vindoline as an intermediate allowed further exploration of its chemistry, in particular the reaction with acetone which yielded a ...

Catharanthine alkaloids are noncompetitive antagonists of muscle-type nicotinic acetylcholine receptors

, 2010
We compared the interaction of several catharanthine alkaloids including, ibogaine, vincristine, and vinblastine, with that for the noncompetitive antagonist phencyclidine (PCP) at muscle nicotinic acetylcholine receptors (AChRs) in different ...

Improvement of the catharanthine productivity in hairy root cultures ofCatharanthus roseus by using monosaccharides as a carbon source

, 1992
Sucrose, glucose, and fructose as carbon sources in culture medium were assessed in hairy root cultures ofCatharanthus roseus. The cultures preferentially consumed sucrose, resulting in about 40% (dry wt) higher growth rate.

Extraction Rates of Vindoline and Catharanthine from Catharanthus roseus with Supercritical Carbondioxide

, 1993
Vindoline and catharanthine were extracted from the pretreated leaves of Catharanthus roseus using supercritical carbon dioxide and their mass transfer coefficients were determined in various conditions of temperature and pressure.
