The chemical composition of the volatile oil from aerial parts of Hypericum triquetrifolium Turra was studied by GC-MS. Fifty components (97.1% of the total composition) were detected in the volatile oil. Germacrene-D (21.7%), β-caryophyllene (18.3%), δ-cadinene (6.4%), trans-β-farnesene (4.3%), α-humulene (3.8%), β-selinene (3.7%), γ-cadinene (3.3%) and trans-phytol (3.2%) were found to be the major constituents of the oil. The oil of H. triquetrifolium consisted of five monoterpene hydrocarbons (3.4%), two oxygenated monoterpenes (0.4%), twenty-two sesquiterpene hydrocarbons (77.1%), eight oxygenated sesquiterpenes (7.9%) and one oxygenated diterpene (3.2%). Twelve nonterpenic compounds were also consisted 5.1% of the oil. In conclusion, the oil of H. triquetrifolium was characterized by a high content of sesquiterpenes (85.0%), whereas monoterpenes contained only 3.8% of the essential oil.
采用气相色谱-质谱联用（GC-MS）技术对三叉叶金丝桃地上部分挥发油的化学成分进行了研究。在挥发油中检测到50种成分（占总成分的97.1%）。发现吉马烯-D（21.7%）、β-石竹烯（18.3%）、δ-杜松烯（6.4%）、反式-β-法尼烯（4.3%）、α-葎草烯（3.8%）、β-芹子烯（3.7%）、γ-杜松烯（3.3%）和反式叶绿醇（3.2%）是该油的主要成分。三叉叶金丝桃的挥发油由5种单萜烃（3.4%）、2种氧化单萜（0.4%）、22种倍半萜烃（77.1%）、8种氧化倍半萜（7.9%）和1种氧化二萜（3.2%）组成。12种非萜类化合物也占该油的5.1%。总之，三叉叶金丝桃的挥发油以高含量的倍半萜（85.0%）为特征，而单萜仅占精油的3.8%。
