What are Olive Oil Terpenoids?

Olive oil has long been known for its health benefits, with studies linking it to reduced risk of heart disease, cancer, and other chronic conditions. One of the key reasons for these benefits is the presence of bioactive compounds called terpenoids, which are found in both olives and olive oil. Terpenoids have been shown to have anti-inflammatory, antioxidant, and antimicrobial properties, among other potential health benefits.

However, while the health benefits of olive oil terpenoids are well established, the process by which these compounds are made in the olive plant is still not fully understood. This knowledge gap is important because understanding the biosynthesis of these compounds could help researchers develop new therapies, improve crop yields, and further explore the health benefits of these compounds.

In this blog post, we'll explore the biosynthesis of olive oil terpenoids, the gene targets identified for high triterpenoid content, and the potential applications of this information for agriculture and medicine.

The Biosynthesis of Olive Oil Terpenoids

Terpenoids are a diverse group of compounds that are found in many plants, including olives. There are several different types of terpenoids found in olives, including triterpenoids like oleanolic, maslinic, and ursolic acids, as well as monoterpenoids like limonene and linalool.

The biosynthesis of terpenoids in olives is a complex process that involves several key genes and enzymes. One of the key enzymes involved in this process is oxidosqualene cyclase (OeBAS), which is required for the production of the major triterpene scaffold β-amyrin. β-amyrin is the precursor to several other triterpenoids, including erythrodiol, oleanolic acid, and maslinic acid.

Another important enzyme involved in the biosynthesis of terpenoids in olives is cytochrome P450 (CYP716C67), which mediates the 2α oxidation of the oleanane- and ursane-type triterpene scaffolds to produce maslinic and corosolic acids, respectively.

Gene Targets for High Triterpenoid Content

Researchers have been working to identify gene targets for high triterpenoid content in olive fruits, and have made some promising discoveries. One of the key steps in this process was identifying the genes and enzymes involved in the biosynthesis of these compounds, which we discussed in the previous section.

Using genome mining, biochemical analysis, and trait-association studies, researchers were able to identify major gene candidates controlling triterpenoid content in olive fruits. They were also able to identify genetic markers associated with oleanolic and maslinic acid fruit content on the chromosomes carrying the OeBAS and CYP716C67 genes.

These genetic markers could be used by farmers to breed olive plants with higher levels of oleanolic and maslinic acids, which are two of the most beneficial terpenoids found in olives. This could lead to healthier olive oil with increased nutritional value, as well as potential applications in the agri-food, cosmetics, and pharmaceutical industries.

Reconstitution of Olive Biosynthetic Pathway in Nicotiana benthamiana

To confirm the function of the genes involved in terpenoid biosynthesis, the researchers used a technique called genetic transformation to introduce these genes into the plant species Nicotiana benthamiana. This technique involves introducing new genetic material into an organism to change its characteristics or properties.

By transferring the genes responsible for terpenoid biosynthesis in olive plants to Nicotiana benthamiana, the researchers were able to confirm the enzymatic functions of the genes and show that they could produce the desired compounds.

The reconstitution of the olive biosynthetic pathway in Nicotiana benthamiana has several implications for plant research and synthetic biology. For example, it could be used to test the function of other genes or pathways in different plant species, which could be useful in developing new crops or in engineering plants to produce useful compounds.

Health Benefits of Olive Oil Terpenoids

Olive oil terpenoids have several potential health benefits that have been studied extensively. Here are some of the most notable health benefits:

Anti-inflammatory properties: Terpenoids in olive oil have been shown to have anti-inflammatory properties, which may help reduce the risk of chronic diseases like heart disease and arthritis.

Neuroprotective and antioxidant properties: Many terpenoids found in olive oil have strong neuroprotective and antioxidant properties, which can help protect cells from damage caused by free radicals.

Antimicrobial properties: Some terpenoids in olive oil have been shown to have antimicrobial properties, which can help prevent the growth of harmful bacteria and viruses.

Anti-cancer properties: Some studies have suggested that terpenoids in olive oil may have anti-cancer properties, although more research is needed in this area.

Cholesterol-lowering properties: Some terpenoids in olive oil have been shown to have cholesterol-lowering properties, which may help reduce the risk of heart disease.

Conclusion

In conclusion, the study of the biosynthesis of olive oil terpenoids has important implications for health and agriculture. Researchers have identified gene targets for high triterpenoid content in olive fruits and confirmed the function of these genes by reconstituting the olive biosynthetic pathway in Nicotiana benthamiana. This information could be used to develop new therapies or improve crop yields by selectively breeding plants with higher levels of beneficial terpenoids.

Olive oil terpenoids have several potential health benefits, including anti-inflammatory, antioxidant, and antimicrobial properties, as well as potential anti-cancer and cholesterol-lowering properties. However, more research is needed to fully understand the health benefits of these compounds and how they interact with other components of the Mediterranean diet and other plant-based foods.
