What specific compound, found as a major component in star anise (*Illicium verum*), was crucial for the production of the antiviral drug Tamiflu?
Answer
Shikimic acid
While true anise (*Pimpinella anisum*) and star anise (*Illicium verum*) share some beneficial compounds like anethole, they are botanically distinct and have different chemical profiles regarding certain key substances. Shikimic acid is specifically identified as a compound found in star anise that held critical importance in the manufacturing pipeline for the antiviral medication Tamiflu. This highlights a key distinction when discussing medicinal applications, as relying on one type of anise may not yield the specific chemical needed for a particular purpose.
