The essential oil extracted from twenty-one plants of Pistacia lentiscus L. growing wild in southern Italy (Salento, Apulia), were investigated by gas chromatography/mass spectrometry (GC/MS). Thirty-eight components, representing more than 75% of the total oil constituents, were identified. The main compounds (with >5% on average) were α-pinene, terpinen-4-ol, δ-cadinene and β-caryophyllene. Four chemotypes were identified: terpinen-4-ol/α-pinene, β-caryophyllene/δ-cadinene/α-pinene, β-myrcene/δ-cadinene and α-pinene. Essential oils showed a radical scavenging activity (2,2-diphenyl-1-picrylhydrazyl; DPPH test) ranging between about 21% and 35%.

Abstract
The essential oil extracted from twenty-one plants of Pistacia lentiscus L. growing wild in southern Italy (Salento, Apulia), were investigated by gas chromatography/mass spectrometry (GC/MS). Thirty-eight components, representing more than 75% of the total oil constituents, were identified. The main compounds (with >5% on average) were α-pinene, terpinen-4-ol, δ-cadinene and β-caryophyllene. Four chemotypes were identified: terpinen-4-ol/α-pinene, β-caryophyllene/δ-cadinene/α-pinene, β-myrcene/δ-cadinene and α-pinene. Essential oils showed a radical scavenging activity (2,2-diphenyl-1-picrylhydrazyl; DPPH test) ranging between about 21% and 35%.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
