Rosolic acid - Introduction
It has a metallic luster. There are also yellow-brown films with dark green metal samples. Soluble in alcohol is golden yellow solution, soluble in sodium hydroxide or potassium hydroxide solution is rouge red, soluble in concentrated sulfuric acid, 70% sulfuric acid, hydrochloric acid or perchloric acid is yellow to orange, slightly soluble in glacial acetic acid, slightly soluble in ether and chloroform, almost insoluble in (0 · 12%) and benzene. Heat to 180 ℃ (volatilization) in vacuum. The maximum absorption wavelength (potassium hydroxide solution) is 534 · 6 and 479 · 5nm. It's irritating.
