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. 展开更多

The volatile and semi-volatile components in flower of Elaeagnus angustifolia were extracted by using simultaneous distillation-extraction and extraction respectively from steam and water residue, and the chemical compositions were determined by GC-MS. The results indicated that the components from water residue were different from those obtained from simultaneous distillation-extraction, which were similar to the literature results. The components in water residue contained benzoic acid(6.94%), benzeneacetic acid(5.49%), salicylic acid(1.21%),cis-cinnamic acid(5.35%), trans-cinnamic acid(20.37%), cis-p-hydroxycinnamic acid(3.96%), trans-p-hydroxylcinnamic acid(1.77%), 3-(3-hydroxyphenyl)-2-propenoic acid(1.66%), cis-3-(4-hydroxy-3-methoxyphenyl)-2-propen-oic acid(1.19%), 4-hydroxy-3-methoxybenzoic acid(6.77%), 4-hydroxybenzoic acid(2.43%), alpha-(phenylmethyl)-benzeneethanol(4.46%), 3,5-dimethoxy-4-hydroxyphenylacetic acid(1.7%), 2,6-dimethyl-1,7-octadiene-3-ol(5.29%), (Z,Z)-9,12-octadecadienoic acid(1.66%), et al. The analysis results showed that flower of Elaeagnus angustifolia is importance plant resource to extract nature perfume, antimicrobial and antioxidant. 展开更多
