[0002] Artemisinin, also known as artemisinin, is an organic compound with the molecular formula C15H22O5 and a relative molecular mass of 282.34. Artemisinin appears as colorless needle-shaped crystals, readily soluble in chloroform, acetone, ethyl acetate, and benzene, soluble in ethanol and ether, slightly soluble in cold petroleum ether, and virtually insoluble in water. Due to its unique peroxide group, it is thermally unstable and susceptible to decomposition by moisture, heat, and reducing substances. The double-cone vacuum drying oven is a highly efficient and uniform drying device widely used in the pharmaceutical, fine chemical, and food industries. It operates under vacuum, heating the material by introducing heat energy through the interlayer of the cylinder. The material is then turned under vacuum, drawing heat from the vessel wall, achieving uniform drying.
