Objective: To analyze compositions of volatile oils and anti-oxidative activities of flowers

stems and leaves of Lonicera japonica collected in Shandong province. Method: The volatile oils were extracted from the flowers

leaves

stems of L. japonica

and the compositions were identified and compared by GC-MS;70% ethanol was used to extract L. japonica flowers

stems and leaves

respectively. After solvents were recovered from the extract

petroleum ether

ethyl acetate

n-butanol were respectively used for extraction. In vitro anti-oxidative activities of the extracts

extracted aqueous phases and volatile oils were compared by employing DPPH scavenging assay. Result: The 49 compositions were separated and identified from different parts of L. japonica and eleven of which were mutual in the flowers

leaves

stems

respectively accounting for 60.66%

77.98% and 80.38% of their volatile oils. Palmitic acid represented the highest percentage in these three parts. All samples of extracts could eliminate free radicals

and the scavenging capacity increased with increasing concentration

but there was difference between various samples. Ethyl acetate extract had the strongest scavenging capacity

followed by N-butyl alcohol extract

aqueous phase

volatile oils

and petroleum ether extract in turn. Conclusion: The volatile oils of flowers

stems and leaves of the plant were highly similar to each other in compositions;all of volatile oils and different polar extracts of these three parts have good antioxidant capacity.
