Shikimic acid

Introduction:

Shikimic acid is a white crystalline powder easily soluble in water. It gets its name because it was first isolated

 from Japanese shikimi and is an important metabolic product of plants and microorganisms. For a long time, 

shikimic acid has been mainly extracted from the dried and ripe fruits of the aniseed family or Japanese shikimic

 (Japanese anise), and in recent years, there are also reports of extracting shikimic acid from the fruits of North 

American maple and pine needles.
