Abstract:
Objective To observe the free radical scavenging action of volatile oil from Piper longum L.growing in Hainan Province and to explore the relationship of the action with molecular structure.Methods 1,1-Diphenyl-2-picrylhydrazyl radical(DPPH) method was used to determine the scavenging action.The components of volatile oil were analyzed by GC-MS,and their molecular structures were identified by databank.Results(1)The volatile oil from Piper longum L.had scavenging actions on free radicals in a concentration-dependent manner.(2)Forty one compounds were found in volatile oil from Piper longum L.growing in Hainan Province,in which the amount of carbon-carbon double bond(C=C) was in predomination.Conclusion Carbon-carbon double bond(C=C)is the essential functional group for free radical scavenging action of volatile oil from Piper longum L.
