Vindoline, the major alkaloid in cultures of Catharanthus roseus shoots, reached 2 mg g(-1) dry wt after 27 d in culture. Maximal vindoline accumulation coincided with maximum activities of deacetoxyvindoline 4-hydroxylase, deacetylvindoline acetyl-CoA acetyl transferase and tryptophan
[Simultaneous determination of vindoline, catharanthine and anhydrovinblastine in Catharanthus roseus by high performance liquid chromatography].

Vindoline was extracted from the leaves of Catharanthus roseus over the ranges of 35-70 degrees C and 100-300 bar using supercritical carbon dioxide with and without the addition of 3 wt % ethanol as a cosolvent. The vindoline contents in the extracts were determined by HPLC and identified by LC/MS.

Catharanthus roseus cell cultures were exposed to different conditions in order to induce alkaloid metabolism. The exposure to jasmonate and fungal elicitors resulted in the transcriptional activation of tryptophan decarboxylase and in the accumulation of the monoterpenoid indole alkaloids
Vindoline formation in shoot cultures of Catharanthus roseus is synchronously activated with morphogenesis through the last biosynthetic step.

OBJECTIVE
The Madagascar periwinkle (Catharanthus roseus) produces the monoterpenoid alkaloid vindoline, which requires a specialized cell organization present only in the aerial tissues. Vindoline content can be affected by photoperiod and this effect seems to be associated with the morphogenetic

Vindoline concentrations in the leaves of 70 CATHARANTHUS ROSEUS of 3 cultivars were analyzed by HPLC, and 3 plants were selected for starting callus cultures on different media. When the initial calli were analyzed using a vindoline-specific RIA, the assay suggested a vindoline content of about 10
[Distribution and accumulation of vindoline, catharanthine and vinblastine in Catharanthus roseus cultivated in China].

OBJECTIVE
The content of vindoline, catharanthine and vinblastine in the root, stem, leaf, flower and fruit of Catharanthus roseus at various developmental stages were determined, and the biomass allocation was also determined to find the best harvest time.
METHODS
The content of vindoline,

From differentiated plants of Catharanthus roseus (L.) G. Don, a specific enzyme was isolated and named acetyl-CoA : 17-O-deacetylvindoline 17-O-acetyltransferase, acting on the biosynthetic formation of the Aspidosperma type alkaloid vindoline.The enzyme shows a high selectivity towards different
Late enzymes of vindoline biosynthesis : S-Adenosyl-L-methionine: 11-O-demethyl-17-O-deacetylvindoline 11-O-methyltransferase and unspecific acetylesterase.
