Abstract

Houttuynia cordata is an aromatic herb with great importance in the food, pharmaceutical and fragrance industries. Previous studies have shown that its essential oil mainly contains two types of compounds, terpenes and aldehydes. The essential oil composition of a newaccesssion from southwest China was investigated. Head-space solid phase microextraction(HS-SPME) and gas chromatography-mass spectrometry (GC-MS) analyses led to the identification of 13 compounds, representing 98.79% of the volatile constituents. Aliphatic aldehydes (69.64%) were quantified as the principal class of the components besides acids (22.83%). However, no terpenoids were detected. The essential oil was dominated bydecanal (42.64%). Decanoic acid (18.67%) and dodecanal (15.04%) were also the major constituents. Comparison of results with previous reports classified the current accession as a new chemotype rich in aliphatic aldehydes and acids, with complete absence of regular mono- and sesquiterpenoids.

 

Key words: Essential oil, Houttuynia cordata, terpenes.
