    Description: Chinese materia medica (CMM), comprising a diverse array of natural substances from plants, animals, and minerals, has been integral to Traditional Chinese Medicine (TCM) throughout history. This study investigates the dynamic evolution of CMM, noting shifts in species for improved therapeutic effects and the abandonment of those with adverse outcomes. By examining historical CMM specimens, particularly those in Dutch collections, tangible evidence of this evolution emerges.The Westhoff collection, spanning 140 years, reveals significant changes alongside enduring practices. A handwritten catalogue accompanying the collection aligns with modern CMM practices, indicating a remarkable continuity. Comparative analyses of historical collections and contemporary CMM in EU markets over three centuries emphasize the stability of core medicinal plant taxa. Additionally, the study validates the delayed luminescence (DL) technique for discerning CMM storage times, showing promising results.Despite challenges in preservation, historical CMM specimens offer unique insights into medicine's history, underscoring their importance for further research and understanding.

    Notes: Summary Two approximate formulae to calculate the eigenvalues of pure quadrupole interaction in Mössbauer effect studies have been proposed and the eigenvalue coefficients in the formulae have been given for various excited states and ground states of the nucleus with different spin. All the eigenvalues of pure quadrupole interaction between both excited state and ground state of nucleus with spinI=3/2÷9/2 and the electric-field gradient with different asymmetry parameter (η=0÷1.0) have been calculated by these formulae. The results show that the accuracies in all the calculations are more satisfactory or same in comparison with those obtained by the formula of Shenoy and Dunlap, especially when the asymmetry parameter of electric-field gradient is larger than 0.8 for the nucleus with spinI=5/2.
