Abstract

Abstract: Objective To observe the micromorphology and ultrastructure of poisonous seed herbs using the stereomicroscope and scanning electron microscope (SEM). Methods After seed herbs were collected, the surface micromorphology of the herbs was observed under a stereomicroscope and SEM, and their surface and transverse characteristics were recorded. Results The micromorphology of these herbs was described in terms of the shape, size, surface and section characteristics. The identification of properties of these herbs was improved; The ultrastructure of crushed materials was summarized to facilitate the identification of crushed poisonous seed herbs. Conclusion Due to the large differences in size, shape and surface characteristics, microscopic studies can quickly detect seed medicinal materials; for medicinal materials that are already powdery, ultrastructural observation can easily identify their characteristics, thereby preventing misuse and mixed use.

Key words: seeds, poisonous medicinal materials, micromorphology, ultrastructure
