A description of the experience

Studies on antimicrobial activities of solvent extracts of different spices.  Keskin D, Toroglu S.; Cine High Vocational School, Adnan Menderes University, Cine Aydin - 09500, Turkey.

The antimicrobial activities of the ethyl acetate, acetone and methanol extract of 12 plant species were studied. The extract of 

  • Capsicum annuum (red pepper) (fruit)

  • Zingiber officinale (ginger) (root),

  • Cuminum cyminum (cumin),

  • Alpinia ficinarum (galingale),

  • Coriandrum sativum (coriander),

  • Cinnamomun zeylanicum Nees (cinnamomun),

  • Origanum onites L. (thyme),

  • Folium sennae (senna),

  • Eugenia caryophyllata (cloves),

  • Flos tiliae (lime),

  • Folium menthae crispae (peppermint)

  • and Piper nigrum (blackpepper)

were tested in vitro against 2 fungi and 8 bacterial species by the disc diffusion method. 

  • Klebsiella pneumonia 13883,

  • Bacillus megaterium NRS,

  • Pseudomonas aeroginosa ATCC 27859,

  • Staphylococcus aureus 6538 P,

  • Escherichia coil ATCC 8739,

  • Enterobacter cloaca ATCC 13047,

  • Corynebacterium xerosis UC 9165,

  • Streptococcus faecalis DC 74,

  • Kluyveromyces marxianus,

  • Rhodotorula rubra

 were used in this investigation. The results indicated that extracts of different spices has shown antibacterial activity in the range of 

  • 7-24 mm 30 microl(-1) inhibition zone Eugenia caryophyllata (clove),

  • 7-20 mm 30microl(-1) inhibition zone Capsicum annum (red pepper) and Cinnamomun zeylanicum (cinnamon) bark,

  • 7-18 mm 30microl(-1) inhibition zone Folium sennae (senna) leaves,

  • 7-16 mm 30 microl(-1) inhibition zone Zingiber officinale (ginger) root,

  • 7-15 mm 30microl(-1) inhibition zone Cuminum cyminum (cumin) seed,

  • 7-14 mm 30 microl(-1) inhibition zone Folium menthae crispae (peppermint), Origanum onites (thyme) leaves and Alpinia ficinarum (galingale) root,

  • 7-12 mm 30 microl(-1) inhibiton zone Piper nigrum (blackpepper),

  • 7-11 mm 30microl(-1) inhibition zone Flos tiliae (lime) leaves,

  • 7-8 mm 30microl(-1) inhibition zone Coriandrum sativum (coriander)

to the microorganisms tested.
