Figure 1

(a) Chromatographic profile obtained by chiral gas chromatography-flame ionization detector of a commercial essential oil of P. sylvestris (1) and (b). primary essential oil of P. sylvestris (36) with (−)-α-pinene (1, RT: 14.3 min, RI cal: 977, RI lit: 977) and (+)-α-pinene (2, RT: 14.7 min, RI cal: 983, RI lit: 980). The red square indicates the distinct sesquiterpene profile, which was lacking in commercial EOs.
