Microscopy is an important tool for both the identification and authentication of botanical materials, in the whole form and as powders. Of all the analytical methods, microscopy is one of the most rapid, revealing, cost-effective and environmentally sound technologies available. Applying microscopic analysis to help gain a better understanding of plant anatomy will help you meet GMP requirements, and will better assist in navigating the industry’s regulatory landscape.

This two-day workshop will familiarize participants with various plant parts at the microscopic level to help in understanding the characteristic cellular features of each plant part examined using botanical microscopy techniques. The basic structure of various tissue types will be discussed and identified using examples of some of the popular botanicals. The workshop's goal is to leave participants with the experience necessary to confidently conduct microscopic analysis on botanical materials.

Discussion will be accompanied by hands-on training. Botanical materials in powder form will be examined.


  • Preparation of botanicals for microscopic examination and general use of reagents;
  • Microscopic features of various plant parts (leaves, stems, barks, woods, flowers, fruits, seeds, subterranean organs);
  • Developing and documenting microscopic assessment in a scientifically valid manner; and
  • Common and uncommon botanical adulterants: how to detect and how to avoid them.
