Vitamin D in plants: Occurrence, analysis and biosynthesis

Jäpelt, Rie Bak

DTU Food — 2011

for many is vitamin D present in several plants. The hypothesis, which is the background for this PhD thesis, is that plants can be a source of vitamin D for humans as well as for animals. The overall aim was to study the occurrence and biosynthesis of vitamin D in plants to test this hypothesis. Most work

Microalgae contain both vitamin D3 and provitamin D3, which suggests that vitamin D3 exist in the plant kingdom and vitamin D3 has

LC–MS/MS with atmospheric pressure chemical ionisation to study the effect of UV treatment on the formation of vitamin D3 and sterols in plants

Jäpelt, Rie Bak; Silvestro, Daniele; Smedsgaard, Jørn; Jensen, Poul Erik; Jakobsen, Jette

Food Chemistry — 2011, Volume 129, Issue 1, pp. 217-225

Some plant species are known to cause calcium intoxification in grazing animals. This has been attributed to the presence of vitamin D3-like activity. However, research into the presence of vitamin D3 in plants has been limited. One reason for this may be limitations in the analytical methods
