Introduction Cinnamaldehyde, cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil, extracted from several species of Cinnamomum (C. verum, C. burmanii, C. cassia), under the family Lauraceae, a group of evergreen trees. The mixed-aldol condensation was type of reaction employed in the experiment; however, simple aldol condensation, also known as self-condensation was one of the expected side reactions in the conducted study. Product Classification | About Us | The formed precipitate was then filtered and then recrystallized using minimum amount of 95% ethanol solution. including trade names and synonyms. Canizzarro reaction (mechanism shown below) was minimized by the addition of the strong base in small portions, before adding the acetaldehyde, and using a dilute solution of it. The study was performed in accordance with the OECD Guideline 103 (Boiling Point).

Possible sources of error in the experiment were: the losses of minimal amount of reagents due to their adherence on the sides of the Pasteur pipets and 50-milliliter beakers; and the losses of the synthesized cinnamaldehyde caused by its adhesion on the sides of the microreflux, surface of the boiling chip and the inside surface of the separatory, caused by the high viscosity of cinnamaldehyde. 100% %Loss by solvation = 0. Cinnamaldehyde has been proven to inhibit microbial growth of opportunistic human pathogenic fungi and various bacteria (Khan and Abourashed, 2011). The difference between the two classifications is that simple aldol condensation utilizes only one aldehyde or ketone substrate while the mixed-aldol condensation uses two different carbonyl compounds as the substrate for the reaction (Fox and Whitesell, 2004). Hi there, would you like to get such a paper? Create . It is a pale yellow to yellow clear liquid to solid, which is nearly insoluble in water but soluble in oils. Balls and sticks representation of 3-hydroxy-3-phenylpropanal in the conformations for the formation of (a) trans-cinnamaldehyde and (b) cis-cinnamaldehyde. 098% V. Discussion Cinnamaldehyde, cinnamic aldehyde or 3-phenyl-2-propenal is the dominant component of cinnamon oil, extracted from several species of Cinnamomum (C. verum, C. burmanii, C. cassia), under the family Lauraceae, a group of evergreen trees. 1 2LDate Submitted: March 12, 2012 MIXED-ALDOL CONDENSATION Synthesis of Cinnamaldehyde I. 06| Acetaldehyde| 1. The synthesized cinnamaldehyde was expected to be constituted of the cis- and trans- diastereomers; however, it was expected that the trans-isomer was the major component of the product.

Decomposition of natural cinnamaldehyde, however, is not observable in baking and cooking due to the presence of eugenol impurities on cinnamon oil, which has antioxidative properties that protect cinnamaldehyde from heat-induced decomposition (“Cinnamaldehyde Content”). The E (trans) stereoisomer of cinnamaldehyde, the parent of the class of cinnamaldehydes. Due to this demarcation in the discovery and investigation of other potential medicinal and non-medicinal values of cinnamaldehyde, chemists have also developed synthetic procedures to obtain high amounts of pure cinnamaldehyde, one of which is the mixed aldol condensation of benzaldehyde and acetaldehyde. The same arrangement was also the experimental arrangement of the compounds with respect to the observed degrees of sootiness after the carried out combustion test. To use blood released from slaughtering houses, a porcine plasma protein (PPP)/nanoclay composite film was prepared. 68| Cinnamaldehyde:| | Theoretical| 3. Simple distillation was done to determine the boiling point of the synthesized cinnamaldehyde; however, decomposition was observed in the middle of the procedure, causing the failure of the melting point determination attempt; but supported that it was possible that cinnamaldehyde. The synthesized cinnamaldehyde was readily separable (solubility of cinnamaldehyde in water=4. IV. Cinnamaldehyde inhibits ROS release and the activation of MAPKs as well as pro-inflammatory cytokines expression within TLRs activated cultured monocytes/macrophages[1] .Cinnamaldehyde induces apoptosis by mitochondrial permeability transition in human promyelocytic leukemia HL-60 cells, and induces apoptosis in human hepatoma cells through activation of the proapoptotic Bcl-2 family proteins[1]. 0mL – filter – recrystallize using 95% ethanol Colored hydrazone crystals Determine melting point and RGB values Compared appearance, melting points and RGB values with other hydrazones 5.

Aldol condensations can be classified as simple and mixed-(or cross-) aldol condensation. Also, cinnamaldehyde has been proven to inhibit microbial growth of opportunistic human pathogenic fungi, such as Aspergillus niger, Candida albicans and Rhizopus oligosporus, and various bacteria (Escherichia coli, Enterobacter cloacae, Micrococcus luteus, Staphylococcus aureus, Streptococcus faecalis, and others) (Khan and Abourashed, 2011). Use caution: Liquids with this reactive group classification have been spaced). LSA+ cinnamaldehyde should be a very stable adduct because the boiling point of cinnamaldehyde is very high.
