How is parsley leaf extract (CAS: 8000-68-8) typically synthesized?

Parsley leaf extract (CAS: 8000-68-8) is typically synthesized through a series of extraction processes using solvents like ethanol or water, followed by purification steps such as liquid-liquid extraction or ultrafiltration. The extract is then concentrated and dried to obtain the final product. This process often involves the use of activated carbon for decolorization to improve the purity of the extract.
