Science & Biotechnology
Sweet osmanthus is the most fragrant tree of the Chinese autumn, its tiny orange or ivory blossoms perfuming whole neighbourhoods and flavouring teas, wines and osmanthus jam. The flower’s aroma chemistry — ionones derived from carotenoid breakdown, with linalool and terpinen-4-ol — is well characterised, and its polyphenols show antioxidant and anti-inflammatory activity in laboratory studies. In Chinese tradition the flowers are a gentle household remedy for cough and bad breath. A single plant in bloom repays decades of patience in one September week.
