The seasonal variation of the essential oil, in terms of both yield and composition, of a population of Santolina etrusca (Asteraceae) is reported in detail for different aerial parts, including sterile branches, fertile branches, and capitula. The yields generally increased from November to June, and then decreased in August and September. The main constituents of the sterile branches were 1,8-cineole and viridiflorol. The oil from fertile branches was characterized by myrcene as principal compound, whereas the essential oil obtained from the capitula contained germacrene D as the main constituent. Several compounds, as identified by GC and GC/MS, were found to prevail during the cold season.
详细报道了伊特鲁里亚神圣亚麻（菊科）群体不同地上部分（包括不育枝、可育枝和头状花序）精油在产量和成分方面的季节性变化。产量一般从11月到6月增加，然后在8月和9月下降。不育枝的主要成分是1,8-桉叶素和绿花白千层醇。可育枝精油的主要成分是月桂烯，而从头状花序中获得的精油以吉马烯D为主要成分。通过气相色谱（GC）和气相色谱-质谱联用（GC/MS）鉴定发现，几种化合物在寒冷季节占主导地位。
