Introduction
Plant materials are used throughout developed and developing countries as home remedies, over the counter drug products and raw materials for the pharmaceutical industry. It is therefore essential to ensure the quality of medicinal plant products by using several techniques and applying suitable standards. One of the most important techniques to authenticate a crude plant drug is the microscopical examination of the crude plant or the plant powder. |
|
The plant material is prepared for microscopical examination and the anatomical features of the powdered drugs are recorded in order to compare the structures present with those drawn and described in the relevant monographs. At the end of the lab course, students are able to interpret the morphological and anatomical descriptions of the crude plant in order to clearly identify it. |
