Table 1.
Aromatic profile of L. angustifolia essential oil from the corolla, calyx, leaf, and whole flowering top. Each reported value below represents the average of three essential oil samples distilled from each portion. Each essential oil sample was analyzed in triplicate. Values less than 0.1% are denoted as trace (t) and those not detected in a portion of the plant as not detectable (nd). Unidentified compounds less than 0.5% are not included. KI is the Kovat’s Index value obtained using a linear calculation on DB-5 column [38]. Relative area percent was determined by GC-FID.
