OBJECTIVE
To investigate the chemical constituents from the essential oil of Hypericum patulum, and provide the scientific basis for exploitation.
METHODS
The essential oil was extracted by steam distillation. The chemical constituents of the essential oil were analyzed by GC-MS. The relative contents of these constituents were calculated using square peaks to normalization.
RESULTS
72 peaks were separated and 24 constituents were identified, which constituted about 79.50% of the total essential oil.
CONCLUSION
The main constituents are alpha-pinene (18.14%), 2,4a,5,6,7,8-hexahydro-3,5,5,9-tetramethyl-,(R)-1H-benzocycloheptene (13.64%), beta-caryophyllene (9.41%), longifolene (6.23%), etc.
目的
研究金丝桃精油的化学成分，为其开发利用提供科学依据。
方法
采用水蒸气蒸馏法提取精油。通过气相色谱-质谱联用仪分析精油的化学成分。采用峰面积归一化法计算各成分的相对含量。
结果
分离出72个峰，鉴定出24种成分，占精油总量的79.50%左右。
结论
主要成分有α-蒎烯（18.14%）、2,4a,5,6,7,8-六氢-3,5,5,9-四甲基-，(R)-1H-苯并环庚烯（13.64%）、β-石竹烯（9.41%）、长叶烯（6.23%）等。
