Olive Oil Phenols Analysis Service

The overall beneficial effect of olive oil on health is well known, and it is widely accepted that some of the beneficial effects are mediated by the phenolic compounds found in the olive.

The species and concentration of the phenolic compounds varies significantly among plant tissues. Oleuropein is the most prominent phenolic compound in olive. The oleuropein molecule consists of three parts: a polyphenol, namely 4-(2-hydroxyethyl) benzene-1,2-diol which is also known as hydroxytyrosol (HT), a secoiridoid called elenolic acid and a glucose molecule. Oleuropein has been demonstrated to have antioxidant, anti-inflammatory, anti-atherogenic, anti-cancer and anti-aging properties, and therefore is commercially available as food supplement in Mediterranean countries.

Hydroxytyrosol is a phenylethanoid. It is the principal degradation product of oleuropein. In nature, during maturation of fruit or as a result of olive processing (such as oil production), the concentration of oleuropein drops and the concentration of hydroxytyrosol increases. Hydroxytyrosol has been reported to have the potential to affect blood lipid levels.

Another compound that is abundantly found in olive is tyrosol. Tyrosol is also found in green wine and green tea. Even though tyrosol has relatively low antioxidant activity, it is more stable due to less autooxidation events. Some epidemiological studies showed a high correlation between a diet particularly rich in biophenols and a lower risk of cardiovascular diseases, and this may due to the antioxidant property of tyrosol, which protect cells against oxidation induced damage.

From Our Clients

"I recently used their proteomics service for a project analyzing protein interactions in yeast models. The team was very responsive and helped clarify the methodology they employed, which made me feel confident in the results. The data quality was solid, with clear identification of several key proteins involved in our study. Their thorough analysis enabled me to pinpoint specific interactions that I hadn't considered before, which significantly improved the direction of my research. I appreciate their professionalism and support throughout the process."

Sarah Thompson, University of California, Berkeley

"Our lab collaborated with them on a project studying cancer biomarkers. The proteomics analysis provided was detailed and focused, specifically highlighting the differential expression of proteins between healthy and tumor samples. Their clear explanations of the data helped my team understand the biological implications. I also appreciated their willingness to revise the reports based on our feedback, ensuring that we had everything we needed for our publication. This collaborative spirit was invaluable."

Emily Rodriguez, Stanford University

"Our lab worked with them on a project studying the effects of diet on gut microbiota using proteomics. They used a label-free quantification method to analyze proteins in fecal samples before and after dietary intervention. The results showed significant changes in protein expression linked to microbial activity. This was pivotal for our hypothesis about diet-microbiota interactions. The clarity of their data presentation made it easy for our team to integrate these findings into our ongoing research."

Dr. Lisa Wong, University of Toronto

"My experience with Creative Proteomics during the mass spectrometry analysis was excellent. We sent in human saliva and mouse brain tissue samples, which they expertly analyzed using both LC-MS and GC-MS techniques. The results were invaluable, revealing key metabolites in the saliva and identifying biomarkers linked to brain function in the brain tissue."

Dr. Emily Carter, Senior Research Scientist

"The overall service from Creative Proteomics was outstanding. They made the entire process seamless and efficient, allowing us to focus on our research. We worked with leaf and root samples from various Arabidopsis genotypes for targeted metabolomics analysis. Their thorough profiling of primary and secondary metabolites gave us important insights into how the plants respond metabolically to environmental stress."

Dr. Laura Henderson, Plant Physiologist

"We had a pleasant collaboration with Creative Proteomics on mass spectrometry analysis of lipids. They conducted a detailed analysis of lipid species, providing us with important insights into lipid metabolism and its relationship with metabolic syndrome disease states."

Dr. Sarah Mitchell, Research Scientist
