| Abstract: |
| OBJECTIVE To analyze the main components and determine the in vitro antioxidant activity of volatile from Phellodendri Amurensis Cortex. METHODS The volatile was obtained from Phellodendri Amurensis Cortex by supercritical CO2 extraction technology, and analyzed the components by GC-MS. The scavenging activity on O2- free radical of volatile was assayed by the adjacent benzene three phenolic autoxidation system. RESULTS The extraction rate was 4.68% of volatile oil from Phellodendri Amurensis Cortex by supercritical CO2. ?hirty components were iedentified from the volatile of Phellodendri Amurensis Cortex. The IC50 value of scavenging effects of the volatile oil on the O2- free radica was 1.44 g·L-1. CONCLUSION The volatile from Phellodendri Amurensis Cortex by supercritical CO2 extraction technology has varied components and exhibites certain antioxidant activity. |
