Description
The alkaloids are organic nitrogenous bases found mainly in plants, which deposit with certain reagents in water. These precipitation reactions can be used to determine the alkaloids' existence and to refine them. The present paper studied three different types of alkaloidal precipitates by X-ray phase-contrast imaging (XPCI) based both on Beijing Synchrotron Radiation Facility (BSRF) and on a nanofocus X-ray tube laboratory system. The XPCI results reveal the needle precipitate of colchicines (amine alkaloid), the micelle precipitate of arecoline (pyridine alkaloid) and the petal precipitate of berberine (isoquinoline alkaloid). Comparison of the results obtained by different methods has been made to verify the feasibility of XPCI's future application to more complicated chemical systems. (authors)
