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.
