The volatile profiles (VOC) and the essential oil (EO) composition from the aerial parts of Salvia broussonetii were analysed. Sesquiterpene hydrocarbons dominate the VOCs from leaves (95.7%) and flowers (67.6%), followed by monoterpene hydrocarbons (2.6 and 29.7%, respectively). The main common compounds are germacrene D, β-bourbonene, α-pinene, α-copaene and α-gurjunene, even if with divergent relative abundances. In the leaf EOs the sesquiterpenes prevail, even if not overwhelmingly (about 50.0%), followed by monoterpenes (23.0-35.0%) and by minor fractions of diterpene hydrocarbons and non-terpene derivates. The most abundant common compounds across the two sampling periods are α-pinene, β-pinene, isobornyl acetate, α-gurjenene, germacrene D and bifloratriene. A morphological characterisation of the trichomes responsible for the productivity in terpenes was also performed. Four different morphotypes were observed on the above ground organs of S. brussonetii: peltates and capitates of type II and III resulted the only producers of volatile substances.
对布氏鼠尾草地上部分的挥发性成分（VOC）和精油（EO）组成进行了分析。倍半萜碳氢化合物在叶片（95.7%）和花朵（67.6%）的VOC中占主导地位，其次是单萜碳氢化合物（分别为2.6%和29.7%）。主要的常见化合物是吉马烯D、β-波旁烯、α-蒎烯、α-可巴烯和α-古芸烯，即使其相对丰度有所不同。在叶片精油中，倍半萜占主导地位，即使并非绝对压倒性（约50.0%），其次是单萜（23.0 - 35.0%）以及少量的二萜碳氢化合物和非萜类衍生物。在两个采样期内最丰富的常见化合物是α-蒎烯、β-蒎烯、乙酸异龙脑酯、α-古芸烯、吉马烯D和双花三烯。还对负责萜类物质产生的腺毛进行了形态学表征。在布氏鼠尾草的地上器官上观察到四种不同的形态类型：II型和III型盾状腺毛和头状腺毛是唯一的挥发性物质生产者。
