Abstract:

The chemical components of volatile oil from the flowers of Prunus lanneciana were determined by gas
chromatography-mass spectrometry (GC-MS). The antioxidant activity of the volatile oil was evaluated by DPPH and
ABTS free radical and sodium nitrite scavenging assays with 1 mg/mL VC or BHT as the positive control. The results
showed that twenty-eight compounds representing 84.54% of the total constituents were identified. Some sesquiterpenoids
and aldehydes were identified as the major components in the volatile oil. It scavenged DPPH and ABTS free
radicals and sodium nitrite in a concentration-dependent manner, and showed better scavenging capacity than 1 mg/mL
VC or BHT.

Key words: flowers of Prunus lanneciana, volatile oil, gas chromatography-mass spectrometry (GC-MS), antioxidant activity
