Ursolic acid CAS 77-52-1
Description
Ursolic acid:
Ursolic acid is a chemical product, formerly known as Ursolic Acid. The high content of ursolic acid is glossy prismatic (anhydrous ethanol) or fine hair-like needle crystal (dilute ethanol), the low content is brownish yellow or yellow-green powder, with a special smell, it is one of the natural plants A five-ring triterpenoid compound.
Melting point 283～288℃. Specific optical rotation [α]D25 +67.5° (C=1,1mol/L potassium hydroxide in alcohol solution). At 15 ℃, ethanol (99%) 1 ml can dissolve 10 mg, boiling 1 ml can dissolve 45 mg. Insoluble in water, still in methanol, ethanol, acetone, pyridine.
