摘要
Volatile and semi-volatile components of Paeonia veitchii roots were extracted respectively from steam and water residue by using water steam distillation,their antibacterial activity were evaluated against 6 bacteria(Escherichia coli,Staphylococcus aureus,Salmonella sp.,Bacillus megaterium,Bacillus brevis,Pseudomonas aeruginosa),and the chemical compositions were analyzed by GC-MS.The results indicated that the volatile components contained 2-hydroxy-benzaldehyde(20.24%),benzoic acid(21.64%),n-hexadecanoic acid(6.84%),oleic acid(8.76%),phenol(1.53%),methyl-salicylate(1.22%),furfural(2.49%),2,2-dimethy1-3-octene(2.22%),et al.,accounting for 97.18% of the volatile chemical components.The semi-volatile components contained 3,4,5-trihydroxy-benzoic acid(29.22%),1,2,3-benzenetriol(14.00%),benzoic acid(21.11%),4-hydroxy-3-methoxy-benzoic acid(3.18%),4-hydroxy-benzeneethanol(1.74%),2-hydroxy-benzaldehyde(1.94%),furfural(2.89%),1-(4-hydroxy-3-methoxy-pheny1)-ethanone(5.91%),5-hydroxymethyl-2-furancarboxaldehyde(3.09%),salicyl alcohol(2.04%),(Z,Z)-9,12-octadecadienoic acid(3.82%),accounting for 95.19% of the semi-volatile chemical components.The volatile and semi-volatile components of Radix Paeoniae Rubra exhibited good activity against Staphylococcus aureus and Salmonella sp.,and the semi-volatile components exhibited significant activity against Salmonella sp.in the terms of hypha growth rate.
Volatile and semi-volatile components of Paeonia veitchii roots were extracted respectively from steam and water residue by using water steam distillation, their antibacterial activity were evaluated against 6 bacteria （Escherichia coli, Staphylococcus aureus, Salmonella sp., Bacillus megaterium, Bacillus brevis, Pseudomonas aeruginosa ）, and the chemical compositions were analyzed by GC-MS. The results indicated that the volatile components contained 2-hydroxy-benzaldehyde （20.24%）, benzoic acid （21.64%）, n-hexadecanoic acid （6.84%）, oleic acid （ 8.76% ）, phenol （ 1.53 % ）, methylsalicylate （1.22%）, furfural （2.49%）, 2,2-dimethyl-3-octene （2.22%）, et al., accounting for 97.18% of the volatile chemical components. The semi-volatile components contained 3,4,5-trihydroxy-benzoic acid （29.22 % ）, 1,2,3-benzenetriol （ 14.00% ）, benzoic acid （21.11% ）, 4-hydroxy-3-methoxy-benzoic acid （3.18%）, 4-hydroxy-benzeneethanol （ 1.74% ）, 2- hydroxy-benzaldehyde （1.94%）, furfural （2.89%）, 1-（4-hydroxy-3-methoxy-phenyl）-ethanone （5.91% ）, 5-hydroxymethyl- 2-furancarboxaldehyde （ 3.09 % ）, salicyl alcohol （ 2.04 % ）, （ Z, Z）-9, 12-octadecadienoic acid （ 3.82 % ）, accounting for 95.19% of the semi-volatile chemical components. The volatile and semi-volatile components of Radix Paeoniae Rubra exhibited good activity against Staphylococcus aureus and Salmonella sp., and the semi-volatile components exhibited significant activity against Salmonella sp. in the terms of hypha growth rate.
