3.1 | Volatile chemical composition of M. humileseeds
Chemical analyses of seed volatiles revealed the presence of several substances. By comparing the results with blank analyses, we found eight compounds that were derived from the M. humile seeds (Figure 2). Among eight peaks, 6 peaks were identified as isobutyl alcohol, isoamyl alcohol, isoamyl hexanoate, linalool, isobutyric acid, and α-terpineol (Table 1). Peaks 2 and 8 could not be identified from the obtained mass spectra.
