摘要：

Baccharis articulata Pers., Baccharis trimera (Less) DC., Baccharis milleflora DC., Baccharis oblongifolia Pers., Baccharis anomala DC., Baccharis calvescens DC., Baccharis uncinella DC., Baccharis axillaris DC., Baccharis mesoneura DC. and Baccharis myriocephala DC. essential oils were obtained by hydrodistillation. Using gas chromatography/flame ionization detector (GC-FID), a total of 48 constituents were identified, representing for 70.3-96.7% of the chemical composition. The yield of essential oil from fresh leaf ranged from 0.02% (B. myriocephala) to 1.89% (B. uncinella). Limonene was the main constituent in all species, while alpha-thujene, alpha-pinene, sabinene, beta-pinene, myrcene, p-cymene, limonene, (E)-beta-ocimene, gamma-terpinene, spathulenol and alpha-cadinol were identified in all samples. Principal Components Analysis and Cluster Analysis revealed that chemical similarity was highest for B. calvescens, B. myriocephala, B. trimera, B. milleflora, B. anomala, B. oblongifolia, B. articulata and B. uncinella.
