Soluble in methanol, ethanol, DMSO and other organic solvents.
● Pelargonium pigment, also known as anthocyanidin, is obtained from 2% hydrochloric acid or ethanol solution with reddish color, 35nt unmelted, soluble in ethanol and methanol, moderately soluble in water, and slightly soluble in chloroform. The anthocyanin yellow fresh salt ligand after removing the sugar group from Tianzhu-Kwaitang first exists in the vacuoles of Tianzhukui plant cytoplasm, which is one of the naturally occurring pigments.
