α-Humulene 是Tanacetum vulgareL. 精油的主要成分，显示出抗炎作用，IC50=15±2 μg/mL。它抑制iNOS和COX-2表达。

α-Humulene is extracted from S.officinalis essential oil.α-Humulene can inhibit tumor cell growth.α-Humulene also shows anti-inflammatory effects, probably by interfering with TNFalpha production and COX-2 and iNOS expression.

S. officinalis essential oil was obtained by hydrodistillation and fractionated with column chromatography; the essential oil and its fractions were analyzed by gas chromatography (GC) coupled to mass spectrometry (MS). The cytotoxic activity was evaluated in cellular lines of breast cancer MCF-7, colon cancer HCT-116, and murine macrophage RAW264.7 cell lines by the MTT assay Results: the sub-subfraction F1.1.1 of S. officinalis essential oil containing alpha-humulene present highest activity on RAW264.7 and HCT-116 with IC(50) values of 41.9 and 77.3 mu g/ml, respectively. The sub-subfraction F1.2.1 of S. officinalis essential oil with trans-caryophyllene(Alpha-caryophyllene) showed less activity on RAW246.7 and HCT-116 with IC(50) values of 90.5 and 145.8 mu g/ml.
