Represents ISMD’s specialised services in newly found and knowns alkaloid detection, structural prediction, and safety analysis across functional foods, botanical supplements, herbal formulations, and pharmaceuticals.
ISMD provides specialised services for the detection, identification, and safety assessment of newly found and known alkaloids in natural products: combining mass spectrometry, molecular networking, and predictive toxicology to meet growing regulatory demands.

What specialised services does ISMD offer for alkaloids?

Regulatory scrutiny of alkaloids is increasing worldwide. This market trend makes precise analysis and thorough safety assessment essential for ensuring market access and compliance with evolving regulations.

At ISMD, we understand the importance of precise analysis and thorough safety assessment when dealing with alkaloid-containing products.

Specialising in the discovery of new alkaloids, whether identified through our own research or in collaboration with clients, ISMD integrated approach to alkaloids analysis combines existing and innovative detection methods with computational predictive toxicology. Additionally, we leverage molecular networks in combination with mass-spectrometry to predict the structure of related alkaloids, such as those present in botanical extracts.

The science behind alkaloids

Alkaloids are a large and structurally diverse group of naturally occurring compounds that are primarily derived from plants, but they can also be found in fungi, bacteria, and animals. These compounds are known for their wide range of pharmacological and toxicological properties, depending on their structure, concentration, and context of use.

Alkaloids are classified based on their chemical structure and biosynthetic origins. Each group of alkaloids has distinct chemical characteristics and biological activities, which influence their therapeutic potential or toxicity. Some alkaloids hold therapeutic potential, offering benefits, such as opioids for pain relief or quinine for antimicrobial and cardiovascular effects. Other alkaloids may pose serious health risks even at low concentrations, including toxicity, addiction, or adverse drug interactions. An illustration of the major groups are shown below.

Well-known alkaloids such as caffeine and nicotine illustrate the dual nature of these compounds, as they can act as stimulants or become addictive depending on the dosage, method of consumption, and intended use.

Another example from the Solanaceae family includes common foods like potatoes, tomatoes, and eggplants, which contain tropane alkaloids in very small, typically non-toxic amounts. In contrast, Belladonna (Deadly Nightshade), a highly toxic plant from the same family, is rich in tropane alkaloids such as atropine, scopolamine, and hyoscyamine.

This dual (therapeutic / toxic) nature of alkaloids makes careful analysis and safety assessment crucial when dealing with alkaloid-containing products.
