Insight into the biological activity of hennosides—glucosides isolated from Lawsonia inermis (henna). Could they be regarded as active constituents instead
Henna is the current name of the dye prepared from the dry leaf powder ofLawsonia inermis(Lythraceae). Several studies have focused on the chemistry and pharmacology of the henna dyeingactive compound, lawsone, obtained from the main constituents of leaves, hennosides, during theprocessing of plant material. However, knowledge regarding the biological activity of hennosidesis largely lacking. In this paper, the redox activity of three hennoside isomers is reported.
