Abstract
The essential oils (EOs) of leaves, flowers and stems of Achillea santolina L. (Asteraceae) collected at complete flowering stage from Southwest of Algeria, were isolated by hydrodistillation and subsequently analyzed by means of GC and GC/MS. Quantitative and qualitative differences in chemical compositions between the studied parts of this plant were observed. The EOs were rich in oxygenated monoterpenes (65.91–79.94%). The major constituents in the flowers, leaves and stems were: camphor (68.12, 65.17, 55.72%), 1,8-cineole (8.22, 4.77, 0.7%) and α-terpineol (2.84, 5.35, 2.76%). The highest EO yields were obtained for the leaves and the flowers (0.59 and 0.49% “v/w”, respectively), whereas, the stems were characterized by very weak yield value (0.05%).
Highlights
The genus Achillea is one of the most important genres of the Asteraceae family and comprises 115 species, which are mainly distributed in Europe, Asia and North Africa (Bremer 1994)
The essential oils obtained by hydrodistillation from the flowers, the leaves and the stems of A. santolina presented strong characteristic odors and yellow colors

Summary
The genus Achillea is one of the most important genres of the Asteraceae family and comprises 115 species, which are mainly distributed in Europe, Asia and North Africa (Bremer 1994). The aerial parts of different species of the genus Achillea are widely used in folk medicine due to various purposes and pharmacological properties in various biological activities, such as, anti-inflammatory (Benedek et al 2007), antimicrobial (Sökmen et al 2003; Ünlü et al 2002), antispasmodic (Yaeesh et al 2006), antiulcer (Abd-Alla et al 2016), and antiradical activities (Ardestani and Yazdanparast 2007; Bali et al 2015) This plant is used as treatment for cancerous cells (Bali et al 2015; Ghavami et al 2010). The volatile oil of A. santolina produced insecticidal and insect repellent activities on both domestic flies and honeybees (Mustafa and Al-Khazraji 2008)
