The composition of the essential oil of Lindera neesiana Kurz fruit was examined by GC-MS, (1)H, (13)C and bidimensional NMR techniques (HMQC, HMBC, COSY, TOCSY). Forty compounds were identified, representing approximately 86% of the oil: Z-citral (15.08%), E-citral (11.89%), eucalyptol (8.75%), citronellal (6.72%), alpha-pinene (6.63%) and beta-pinene (5.61%) were the major components. The essential oil of L. neesiana fruit showed significant antimicrobial activity against Staphylococcus aureus and Candida albicans at non-cytotoxic doses in human keratinocytes, suggesting possible topical applications. GRAPHICAL ABSTRACT: The essential oil of Lindera neesiana was investigated by GC-MS and NMR techniques. Its biological activities suggest possible topical applications.

The composition of the essential oil of Lindera neesiana Kurz fruit was examined by GC-MS, (1)H, (13)C and bidimensional NMR techniques (HMQC, HMBC, COSY, TOCSY). Forty compounds were identified, representing approximately 86% of the oil: Z-citral (15.08%), E-citral (11.89%), eucalyptol (8.75%), citronellal (6.72%), alpha-pinene (6.63%) and beta-pinene (5.61%) were the major components. The essential oil of L. neesiana fruit showed significant antimicrobial activity against Staphylococcus aureus and Candida albicans at non-cytotoxic doses in human keratinocytes, suggesting possible topical applications. GRAPHICAL ABSTRACT: The essential oil of Lindera neesiana was investigated by GC-MS and NMR techniques. Its biological activities suggest possible topical applications.
