Abstract

Abstract: The presence of anthocyanidins and anthocyanins were analyzed in flowers of 30 taxa of Aconitum . Delphinidin was detected as a major anthocyanidin from the hydrolysate of 29 taxa with violet and violet-blue flowers. Pelargonidin was identified as a major anthocyanidin in one taxon with white flowers (partially pale reddish purple; White group N155C by R.H.S. Colour Chart). This is the first reported detection of pelargonidin as a major anthocyanidin from Aconitum flowers. Pelargonidin was also found in ten taxa as a minor anthocyanidin, whereas cyanidin was detected from the flowers of all 30 taxa as a minor anthocyanidin. Two anthocyanins polyacylated by p -hydroxybenzoic acids, violdelphin and monodeacylcampanin were identified from 29 taxa with violet and violet-blue flowers as major anthocyanins. This is the first reported isolation of monodeacylcampanin from Aconitum flowers. The structures of these two anthocyanins were elucidated on the basis of Nuclear Magnetic Resonance (NMR) and Mass Spectrometry (MS). Graphical abstract: Image 1 Highlights: Anthocyanidins and anthocyanins in flowers of 30 taxa of Aconitum were surveyed. Twenty-nine taxa contain delphinidin as a major anthocyanidin. One taxon contains pelargonidin as a major anthocyanidin. All flowers contain cyanidin as a minor anthocyanidin. Violet and violet-blue flowers contain violdelphin and monodeacylcampanin as major anthocyanins. This is the first reported isolation of monodeacylcampanin from Aconitum flowers.
