Resins are complex mixtures of organic compounds produced by a wide variety of plants, especially trees.
They are typically composed of volatile and non-volatile hydrocarbon compounds, primarily terpenes and their oxidation products.
Resins have several functions in plants, listed below:
Protective Role
- They act as a protective barrier against insects and other herbivores. When a plant is damaged, the resin can form a seal
over the wound to prevent insect invasion and infection by microbial pathogens.
Healing Mechanism - Resins can aid the healing process after physical
damage. They form a protective layer over wounds, preventing further injury and helping the plant repair itself.
Detoxification Process - Some plants produce resins to isolate and
compartmentalize toxic metabolic byproducts.
Resins are most commonly associated with coniferous trees (like pines and firs), but they are also found in some flowering plants.
They have been used by humans for thousands of years in various applications, including:
Medicine
- Some plant resins have antimicrobial properties and have been used in traditional medicine. For example, the resin from the
Boswellia tree (frankincense) has been used for its potential anti-inflammatory and anticancer properties.
Industry - Resins are used in a wide range of industrial applications,
including the production of varnishes, adhesives, and sealing waxes.
Perfumery - Some plant resins, like frankincense and myrrh, are used
in the production of perfumes due to their aromatic properties.
Food and Drink - Some resins are used in food and drink.
For example, mastic resin from the mastic tree (Pistacia lentiscus) is used in the production of chewing gum,
bakery products, and certain liqueurs.
Examples of some flowers where resins are found are listed below:
Poppy
- Some poppy species produce a latex that is rich in alkaloids, which can be considered a form of resin.
The most famous is the opium poppy (Papaver somniferum), whose latex contains morphine, codeine, and other alkaloids used in medicine.
Dahlia - Some species and cultivars of dahlia produce a resin in their flowers
that has been used in traditional medicine.
Marigold - Marigold flowers contain resinous substances that have been
used in traditional medicine for their antimicrobial and anti-inflammatory properties.
Sunflower - Sunflower capitula (the part of the flower where the seeds develop)
contain a resin that has been used in traditional medicine.
Asteraceae Family - Many plants in the Asteraceae family produce a resinous
substance in their flowers and other tissues. Some of these resins have been used in traditional medicine or as bases for fragrances.
Examples of some common resins found in barks are provided below:
Pine Bark Resin
- The resin has been used for a wide range of purposes, from making varnish and adhesives to treating wounds in traditional medicine.
Spruce Bark Resin - Has been used in traditional medicine for its
antimicrobial properties and it is also used in the manufacture of certain products like varnishes and adhesives.
Frankincense - This resin comes from the bark of trees in the Boswellia genus.
It has been used for thousands of years in religious ceremonies, and it is also prized for its potential anti-inflammatory and anticancer properties.
Myrrh - Like frankincense, myrrh is a resin that is harvested from the bark of
trees, specifically those in the Commiphora genus. Myrrh has been used in traditional medicine, as well as in perfumery and religious ceremonies.
Gum Arabic - This resin comes from the bark of the Acacia senegal
tree and other species in the Acacia genus. Gum arabic is used in the food industry as a stabilizer, in the production of inks,
and in traditional medicine.
Copal - This is a term used for the aromatic resins produced by a number
of different trees, and it can be harvested from the bark. Copal has been used in the production of varnishes and in traditional medicine.
Mastic - This resin is produced by the bark of the Pistacia lentiscus tree.
It is used in the production of chewing gum, in cooking, and in traditional medicine.
Balsam Fir Resin - The balsam fir tree (Abies balsamea) produces a resin
that is used in traditional medicine, as well as in the manufacture of glues and varnishes.
The extraction process, including the solvents and methods used, can influence the concentration and types of sterols present in the final extract.
It is often the case that a balance needs to be found between fully-extracting all sterols while also ensuring that the compounds that are
obtained are of a high quality and not degraded.
At Celignis we have extensive experience in the design and optimisation of extraction protocols for a wide variety of chemical constituents from
many different biomass types. If needed we can also work on processes to separate and purify the target compounds.

Celignis is a Partner in 3 Successful Proposals for EU Funding
We are pleased to announce that three of the proposals involving Celignis, submitted to the CBE-JU programme for funding collaborative biomass research in Europe, were successful. These projects will provide an additional funding of €1.5m to Celignis and build on our achievements in other CBE and EU projects. In particular, the projects are all at enhanced TRLs (6/7) and will use our existing Celignis Bioprocess infrastructure and will also fund further development of our bioprocessing capacities and the Bioprocess Development Services we offer our clients.
Details on the funded projects are provided below:
BIONEER - This project was funded under CBE-JU topic IA-06 and focuses on the TRL 6/7 production of biobased platform chemicals. Celignis's activities in the project focus on scaling up the work undertaken in our ongoing
Celignis to Exhibit and Present at Major Biochar Event
The 2024 North American Biochar Conference will take place in Sacramento, California, on Feb 12-15
On Feb 12-15 we'll be exhibiting at the 2024 North American Biochar Conference, taking place at the SAFE Credit Union Convention Centre in Sacramento, California.
We're looking forward to interacting with the 1000+ expected attendees, outlining our extensive range of analytical and application testing services for biochar.
Celignis CIO Lalitha Gottumukkala will also be a member of the expert panel focused on developing improved laboratory methods for biochar characterisation.
This Networking Event Will Involve Discussions on Collaborations for Proposals to the 2024 CBE-JU Topics
The Circular Bioeconomy Europe Joint Undertaking (CBE-JU) is an organisation that funds biomass research in Europe at various Technology Readiness Levels (TRLs). Since 2016 Celignis has been an active participant in a number of projects funded by the CBE-JU.
The Biobased Industries Consortium (BIC) is the steering committee that helps to steer the focus of research for the CBE-JU programme. In 2023 Celignis joined the BIC as a Full Industry Member and participated in several proposals submitted for different research topics in the CBE-JU's 2023 Work Programme.
