acetylshikonin/echium

Echium plantagineum L. (Boraginaceae) is an invasive species in Australia and contains medicinal shikonins in its roots. In this study, the hairy root lines of E. plantagineum were established using Agrobacterium rhizogenes strain ATCC15834 and confirmed by the amplification of

Metabolic profiling can be successfully implemented to analyse a living system's response to environmental conditions by providing critical information on an organism's physiological state at a particular point in time and allowing for both quantitative and qualitative assessment of a specific

BACKGROUND The roots and root barks of Echium sp. have been used to treat ulcers, burns and wounds in traditional Turkish medicine. OBJECTIVE On the basis of them traditional use and literature references, four Echium species were selected for evaluation of them wound healing potential. Isolation of

Isohexenylnaphthazarins are commonly found in the root periderm of several Boraginaceous plants and are known for their broad range of biological activities. The work described herein concerns the biological activity of compounds from the roots of Echium plantagineum L. and Echium gaditanum Boiss

Nine shikonin pigments: shikonin (S), acetylshikonin (AS), propionylshikonin (PS), isobutyrylshikonin (IBS), tiglylshikonin (TS), 3,3-dimethylacrylshikonin (DAS), angelylshikonin (ANS), 2-methyl-n-butyrylshikonin (MBS) and isovalerylshikonin (IVS) were identified in the root epidermis of Echium

Bioactive plant secondary products are frequently the drivers of complex rhizosphere interactions, including those with other plants, herbivores and microbiota. These chemically diverse molecules typically accumulate in a highly regulated manner in specialized plant tissues and organelles. We

The phytochemical investigation of the n-hexane extract from callus and cell suspension culture of Arnebia euchroma (Royle) Jonst. resulted in the isolation of nine isohexenylnaphthazarins: deoxyalkannin (1), alkannin (2), acetylalkannin (3), isobutyrylalkannin (4), β-hydroxyisovalerylalkannin

In the present study, five root extracts of Onosma visianii Clem were investigated for their in vitro cytotoxic activity. On the basis of HPLC-PDA analysis, these extracts have proved to be a rich source of naphthoquinones as natural colourants for food and cosmetic industry. All investigated root
