Artemisinin

Chemical formula: C₁₅H₂₂O₅

Artemisinin is an organic compound, not a mineral; it is a crystalline substance of plant origin, primarily known for its medicinal applications.

## Characteristics Artemisinin is a sesquiterpene lactone containing a peroxide bridge. In its pure form, it creates colorless, needle-like crystals. It is not classified as a mineral because it is an organic compound of biological origin (obtained from the plant *Artemisia annua*) and does not meet the definition of a mineral (it is not formed by natural geological processes). ## History and Name It was discovered in 1972 by Chinese chemist Tu Youyou, who received the Nobel Prize in Physiology or Medicine in 2015 for her research on artemisinin and its application in treating malaria. The name comes from the genus name of the plant from which it is isolated - *Artemisia* (wormwood). ## Applications Artemisinin and its derivatives are key substances used in the development of antimalarial drugs. Their unique mechanism of action, based on the reaction of the peroxide bridge with iron inside the malaria parasite, makes them effective in treating this disease.

Properties

Density: 1.24
Crystal system: Orthorhombic

Diagnostic features

Artemisinin is not a mineral and is not subject to standard mineralogical diagnostics. Identification is carried out under laboratory conditions using chemical methods, such as chromatography or mass spectrometry.

Geological environment

Artemisinin is not a mineral and does not form in geological environments. It is a product of the secondary metabolism of sweet wormwood (*Artemisia annua*), a plant originating from Asia.

Rarity

Not applicable (organic compound)

For collectors

Artemisinin is not of interest to mineral collectors because it is not a mineral. Its value lies in pharmaceutical applications.

Care and storage

## Cleaning As an organic compound, crystalline artemisinin is a laboratory substance and is not collected as a geological specimen. The purity of the substance is crucial, and "cleaning" in the mineralogical sense does not apply. In the laboratory, appropriate solvents are used for recrystallization. ## What to avoid High temperatures, which can lead to thermal decomposition, should be avoided. The substance is sensitive to strong acids and bases. It should be protected from exposure to UV light, which can cause its degradation. ## Storage Store in tightly sealed, light-resistant containers, in a cool, dry, and well-ventilated place, away from heat sources and direct sunlight.
