The glucosinolate patterns in seeds of five ISATIS TINCTORIA and two ISATIS INDIGOTICA accessions were assessed with a recently developed and validated LC-MS assay for direct analysis of glucosinolates without prior desulfatation. Glucosinolate peaks were identified with in-source fragmentation and detection of the sulfate anion ( M/Z = 97), and by MS/MS experiments. The glucosinolate patterns of the seeds showed characteristic differences compared to leaves. Glucoisatisin and epiglucoisatisin…

Glucosinolates: Novel sources and biological potential

In this chapter, some of the most recent information on glucosinolate-containing plant families is presented and it was shown that only a limited number of the reported 120 GLs are available in fair quantities, acceptable for further investigation of the biological potential.

Insights into glucosinolate accumulation and metabolic pathways in Isatis indigotica Fort.

Ten different GSLs with their accumulation patterns and 132 genes involved in the GSL metabolic pathway were explored, which laid a foundation for the study of GSL metabolism and regulatory mechanisms in Isatis indigotica Fort.

Composition of Indigo naturalis.

A proposal for a European Pharmacopoeia monograph concerning Indigo naturalis, whereby the indigo and indirubin content should be determined by HPLC-UV was tested, but problems were seen with the dosage of indigo due to poor solubility.

Seasonal changes and effect of harvest on glucosinolates in Isatis leaves.

It is found that repeated harvest did not have a major effect on glucosinolate concentrations of newly grown leaves and could not be detected in woad leaves submitted to conventional drying.

Distribution and Variation of Indole Glucosinolates in Woad (Isatis tinctoria L.).

High levels in woad of three indolic goitrogens are compatible with earlier suggestions that the compounds could be auxin precursors at the time of flower stem elongation and pathways of goitrogen biosynthesis should be relatively easily determined in this material.

Tryptanthrin content in Isatis tinctoria leaves--a comparative study of selected strains and post-harvest treatments.

Tryptanthrin appears thus to be a product of post-harvest processes, but details of its formation remain to be elucidated.

Isatis tinctoria – From the rediscovery of an ancient medicinal plant towards a novel anti-inflammatory phytopharmaceutical

Dichloromethane and carbon dioxide extracts showed in vivo anti-inflammatory activity in topical and oral application and tryptanthrin was found to penetrate the skin with the aid of electrospray ionization liquid chromatography-mass spectrometry coupled skin microdialysis.

A metabolite‐profiling study of shock‐frozen leaves of Isatis tinctoria L., an old indigo dye plant and medicinal herb, revealed a complex pattern of indigo‐forming compounds with higher polarities

Identification and isolation of the cyclooxygenase-2 inhibitory principle in Isatis tinctoria.

Various extracts prepared from the traditional dye and medicinal plant Isatis tinctoria L. were submitted to a broad in vitro screening against 16 anti-inflammatory targets, leading to the identification of tryptanthrin as the constituent responsible for essentially all COX-2 inhibitory activity in the crude extract.
