leucojum/tyrosine

The results described in these studies proved that the successful in vitro bioproduction of galanthamine from L. aestivum shoot-clumps required mainly the selection of in vitro clones with a genetically determined high ability to produce the desired alkaloids, although the expression of this ability

The fresh bulbs of Leucojum vernum provided seven tyrosine-derived alkaloids; two of them have not been reported before and are named leucovernine and acetylleucovernine. The five known alkaloids were N-demethylgalanthamine, hippeastrine, 9-O-demethylhomolycorine, 5alpha-hydroxyhomolycorine, and

The effects of methyl jasmonate and jasmonic acid on galanthamine production, phenolic acid content and growth of Leucojum aestivum L. shoot culture, cultivated in submerged conditions were investigated. The best time-point for addition of elicitors was during the exponential phase of the culture
