Search and find olive oil compounds with OliveNet

Olive oil is now widely recognized as a key component of the health benefits provided by the “Mediterranean diet”. However, the exact composition and biological activity of olive oil and its compounds are still being investigated. OliveNet aims at gathering all information on olive oil compounds in a knowledgebase. Here, they briefly present their database and its features.

 

The benefits of olive oil

 

The health benefits of a Mediterranean diet rich in extra-virgin olive oil was illustrated by the classical Ancel Keys Seven Countries Study and more recently the methodical, multicentre Prevention with Mediterranean (PREDIMED), trial in Spain. In the context of health benefits the initial focus was on the major mono- and poly-unsaturated fatty acids, and accumulated evidence now highlights the beneficial effects of minor constituents of extra-virgin olive oil, particularly the phenolic compounds.

 

The OliveNet database

 

There is ample literature regarding the total pool of olive-associated compounds; for example, over 200 olive-associated phenolics have been described. However, the information is disparate, not easily searchable and the bioactivity and biological effects of only a small compounds has been investigated to date.

 

Addressing this, OliveNet is a comprehensive database of compounds from Olea europaea. The database details a total of 676 compounds from the various olive matrices. The compounds are classified into 13 major classes and 47 subclasses (Figure 1 and 2)

Figure 1. The OliveNet database consists of a total of 676 individual compounds categorized into 13 classes.
Figure 2. The OliveNet database consists of 222 individual phenolic compounds divided into 13 subclasses.

Information about individual compounds of interest including concentration analyses from various sources, MeSH classifications, useful external links, and extensive lists of relevant publications are provided (Figure 3).

Users can find specific compounds of interest by selecting the olive compound group to which their compound belongs at the top of the library page, narrowing their selection down to the subgroup it comprises, and opening up the subgroup and picking their specific compound.

 

For example, if searching for hydroxytyrosol you would select phenols, simple phenols then hydroxytyrosol (Figure 4). Another way to find your compound of interest is to use the search bar at the top of each website page.

 

The OliveNet database is meant to be an interactive way for olive researchers to gain information and contribute to the knowledge of other olive researchers. The database is freely available at: www.mccordresearch.com.au.
