Triterpenoids in aronia berries as a potential cancer treatment
Aronia berries (Aronia melanocarpa), also known as chokeberries, are small, dark berries native to North America. They are considered a rich source of plant antioxidants, which are known to offer many health-promoting properties.
Aronia berries contain phenolic compounds and triterpenoids, which are the major antioxidant components of the fruit. These active components are believed to be responsible for the majority of the bioactivities observed in Aronia berries, including potential health benefits such as antidiabetic, anti-infective, antineoplastic, and antioxidant activities.
The abundance of potent antioxidant phenolic compounds and triterpenoid constituents in Aronia berries supports their potential as a cancer treatment. Test-tube studies have shown that the antioxidants in Aronia berries can inhibit free radical activity, which is significant because a buildup of free radicals can lead to oxidative stress and chronic conditions like cancer. Additionally, test-tube and animal studies indicate that the anthocyanins in Aronia berries may stop the growth of colon cancer cells.
Furthermore, the triterpenoid constituents of Aronia berries, such as ursolic acid, have exhibited anti-inflammatory activity and potential antitumor activity. A phase I study found that a liposomal form of ursolic acid was safe and well-tolerated, and it showed potential for improving patient remission rates. Triterpene esters derived from ursolic acid have also been found to inhibit the activity of breast cancer stem cells, suggesting their potential as new breast cancer chemotherapeutic agents.
While Aronia berries show promising results in test-tube and animal studies, more human studies are needed to evaluate their effectiveness in cancer treatment. A 12-week randomized, placebo-controlled trial on former smokers consuming Aronia berry extract did not show a significant change in biomarkers of oxidative stress or total antioxidant activity. Therefore, further clinical trials are required to optimize the active dose and study the toxic effects of Aronia berries.

Triterpenoids' water solubility
Triterpenoids are a large class of terpenoids that contain a 30-carbon chain structure, consisting of six consecutive isoprene units concatenated in head-tail or non-head-tail order. They are derived from squalene or related acyclic 30-carbon precursors. Triterpenoids are a structurally diverse group of natural products, with over 100 distinct skeletons identified.
Triterpenoids can be isolated from stem bark using percolation and a nonpolar solvent such as hexane, ether de petrol, and chloroform. However, triterpenoids with glycosyl moiety require more polar solvents like ethyl acetate, methanol, and sometimes water. The solubility of triterpenoids in water depends on their specific chemical structure and functional groups. While some triterpenoids may have limited solubility in water, others may be more soluble in organic solvents or a combination of solvents.
Triterpenoids are known for their diverse biological activities, including anti-inflammatory, antioxidant, and potential anticancer properties. Aronia berries, also known as chokeberries, are a rich source of triterpenoids, among other beneficial compounds. These berries have gained popularity among health-conscious consumers due to their high content of antioxidants and potential health benefits.
The extraction and isolation of triterpenoids from Aronia berries can be achieved through various methods, including maceration using different solvents such as hexane, chloroform, ethyl acetate, and hydroalcohol. The choice of solvent depends on the specific triterpenoids being targeted. While some triterpenoids may be more readily extracted using non-polar solvents, others may require more polar solvents or a combination of different solvent systems.
The solubility of triterpenoids in water can also be influenced by temperature, pressure, and other experimental conditions. In some cases, warming the mixture or vortexing may be necessary to enhance the solubility and dissolution of triterpenoids in water or other solvents. Overall, the water solubility of triterpenoids varies depending on their specific chemical structure, functional groups, and experimental conditions.

Anti-inflammatory properties of triterpenoids
Aronia berries (Aronia melanocarpa) are small, dark berries that have become popular among health-conscious consumers. They are considered a rich source of plant antioxidants, which are said to offer many health-promoting properties. The berries have been found to show multiple bioactivities that are potentially beneficial to human health, including antioxidant, antidiabetic, anti-infective, antineoplastic, and antioxidant activities, as well as heart, liver, and neuroprotective effects.
Triterpenoids are one of the major active components of Aronia berries. They possess potent antioxidant activity, which contributes to the majority of the other bioactivities observed for Aronia berries. Scientific studies have shown triterpenoids to be potential anti-inflammatory and anticancer agents. The anti-inflammatory activity of triterpenoids has been tested against carrageenin-induced oedema and formaldehyde-induced arthritis in albino rats. The triterpenoids of the oleanene and ursene series and filicene were found to be active in both tests. Lupeol, lupeol linoleate, and indomethacin showed a reduction in paw swelling by 39%, 58%, and 35%, respectively, in adjuvant arthritis. Ursolic acid, a triterpenoid compound, has also exhibited anti-inflammatory activity by targeting histamine, lipoxygenase, cyclooxygenase, phospholipase, nitric oxide, and ROS, which play a role in mediating antitumor activity.
Avicins, which are electrophilic pentacyclic triterpenoids, possess proapoptotic, anti-inflammatory, and antioxidant properties. The anti-cancer activities of triterpenoids are mediated by their ability to block TNF-induced NF-κB activation by inhibiting IKKβ. Synthetic triterpenoids, such as CDDO-Im, also block NF-κB activation through direct inhibition of IKKβ. The molecular targets of synthetic oleanane triterpenoids include pathways involving STAT, IL-6, TGF‑β, and KEAP1 (the inhibitor of the transcription factor Nrf2).
In addition to their anti-inflammatory properties, triterpenoids have been found to possess cytoprotective, tumor-differentiating, proliferation–arresting, and apoptotic effects. Triterpenoids have also been studied for their potential in treating and preventing chronic diseases, including cancer. Test-tube studies indicate that the antioxidants in aronia berries can inhibit free radical activity and reduce oxidative stress, which is associated with chronic conditions such as heart disease and cancer.

They are considered one of the richest sources of plant antioxidants, offering many health-promoting properties. Aronia berries are particularly high in anthocyanins, which give them their distinctive colour. They are also a great source of polyphenols, a group of antioxidants that includes phenolic acids, anthocyanins, and flavanols.
Triterpenoids are a type of compound found in Aronia berries. Ursolic acid and quercetin are the major triterpenoid components of Aronia berries. Ursolic acid has been found to exhibit anti-inflammatory activity and has shown potential for improving patient remission rates. It has also been identified as an active compound of an ethyl acetate-soluble extract of Aronia berries.
The COVID-19 pandemic, caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has been a significant threat to global public health. There is currently no known specific drug to combat this virus, and natural products are being used as antiviral agents and immune boosters. Licorice triterpenoids, in particular, have been found to potently inhibit SARS-CoV-2 infection by targeting the virus's entry and replication. The triterpenoids GA (glycyrrhetinic acid) and A3 (licorice-saponin A3) have been identified as having this effect, with EC50 values of 3.17 μM and 75 nM, respectively. These triterpenoids may contribute to the clinical efficacy of licorice for COVID-19 treatment and could be promising candidates for antiviral drug development.
In addition to licorice, other natural sources of triterpenoids have been investigated for their potential to manage COVID-19. For example, specific plant terpenoids and lignoids from Diospyros leucomelas have been found to possess potent antiviral activities against SARS-CoV-2. Furthermore, triterpenoids from Combretum imberbe exhibit antimicrobial and anti-inflammatory activity. These findings suggest that triterpenoids from various natural sources could play a role in the management of COVID-19.
