Provenancing Flower Bulbs by Analytical Fingerprinting: Convallaria Majalis

The origin of agricultural products is gaining in appreciation while often hard to determine for various reasons. Geographical origin may be resolved using a combination of chemical and physical analytical technologies. In the present case of Lily of the Valley (Convallaria majalis) rhizomes, we investigated an exploratory set of material from The Netherlands, three other European (EU) countrie...

Determination of progesterone in vegetative organs and cell organelles of Convallaria majalis L. by radioimmunoassay.

Progesterone was extracted from leaves and subterranean parts of Convallaria majalis L. and quantified by radioimmunoassay. During the stage of flowering the content of progesterone in rhizomes was by a factor of four higher than in leaves and by a factor of ten higher than in roots, whereas five weeks later the level of progesterone was unchanged in rhizomes and roots but was elevated in the l...

Origin of Cardenolides in Rhizomes and Roots of Convallaria majalis L. Biogenesis in situ or Transport from Leaves?

After administration of sodium fl —14C]acetate to rhizome or root cuttings of Convallaria maja­ lis L. two of the main cardiac glycosides were isolated and examined for incorporated radioactivity. With a detection limit of 0.0003% of incorporated label it can be assumed, that the subterranean organs o f C. majalis are not capable of cardenolide biogenesis de novo. Interconversions on the carden...

Steroidal Glycosides from Convallaria majalis Whole Plants and Their Cytotoxic Activity

Phytochemical examination of Convallaria majalis (Liliaceae) whole plants yielded 15 steroidal glycosides (1-15), including nine new compounds (4-6, 10-15) with a lycotetrose unit. The structures of the new compounds were determined using two-dimensional Nuclear magnetic resonance (NMR) analyses and chemical methods. The isolated compounds were evaluated for cytotoxicity against HL-60 human pro...

The impact of extensive clonal growth on fine-scale mating patterns: a full paternity analysis of a lily-of-the-valley population (Convallaria majalis).

BACKGROUND AND AIMS The combination of clonality and a mating system promoting outcrossing is considered advantageous because outcrossing avoids the fitness costs of selfing within clones (geitonogamy) while clonality assures local persistence and increases floral display. The spatial spread of genetically identical plants (ramets) may, however, also decrease paternal diversity (the number of s...
