[Chemical constituents in volatile oil from the flos of Dendranthema indicum var. aromaticum var. nov].

OBJECTIVE

To analyse chemical constituents of volatile oil from Dendranthema indicum var. aromaticum var. nov. by GC-MS.

METHOD

The volatile oil was extracted from Dendranthema indicum var. aromaticum var. nov. through steam distillation and was analysed with different kinds of capillary columns to find out the optimal conditions. The content of compositions of volatile oil was determined with normalization method, and the constituents were identified by GC-MS.

RESULT

44 Components were separated and identified, which accounted for over 43% of total volatile oil.

CONCLUSION

The main constituents in the essential oils from Dendranthema indicum var. aromaticum var. nov. are Verberol, (-)zingiberene, beta-sesquiphellandrene, farnesene, transchrysanthenyl acetate, and caryophyllene.
