3.1. Volatile composition of coated repellent films
A typical chromatogram of the PP film coated with citronella EO
(film A) is shown in Fig. 1a. The MHS-SPME analysis was able to
quantify 6 major compounds, as shown in Table 1: citronellol, geraniol
and their acetates, together with citronellal and eugenol represent
almost 50% of the total chromatographic area. Among the major compounds,
elemol and δ-cadinene were not quantified as a commercial standard was not available, while myrcene and trans-β-ocimene did
not follow the linear relationship ln Ai versus i-1.
