[Study on chemical constituents from essential oil of Hypericum patulum].
Zhong Yao Cai. 2009 Feb; 32(2):224-6.ZY

Abstract

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.
