Abstract

The essential oils from the leaves and rhizomes, roots of the Asarum geophyllum was collected in Duc Quang commune, Ha Lang dicstrict, Cao Bang province was obtained by steam distillation. The yield of essential oil from the leaves and rhizomes, roots was 0,16% and 0,12% in term of air-dry material. Essential oils are white, heavier than water. By using GC/MS analysis, there were 47 constituents from leaves were identified accounted for 97.17% of essential oil by weight. The main constituents of leaves essential oil were β-caryophyllene (11.91%), 9-epi-β-caryophyllene (27.16%), α-humulene (6.69%), bicyclogermacrene (16.98%). Similarly, 56 constituents from twigs were identified and accounting 91,57% of essential oil. The main constituents of rhizomes essential oil were β-pinene (12.61%), aristolene (7.01%), β-gurjunene (5.98%), 9-epi-β-caryophyllene (7.88%), Eudesm-7(11)-en-4-ol (16.94%). This is the first study on the chemical constituents of essential oils from the leaves and rhizomes of Asarum geophyllum in Vietnam.
