While modern labs use for definitive results, micro-chemical tests remain relevant because:

Unlike macro-chemical tests that rely on color changes in a test tube, micro-chemical tests focus on the formation of when a specific reagent is added to an alkaloid sample on a microscope slide. This method is highly sensitive, often requiring only a tiny fraction of the substance. Key Reagents and Their Uses SOME MICRO-CHEMICAL TESTS FOE ALKALOIDS SCIENTI...

A drop of the specific reagent is added to the edge of the sample. While modern labs use for definitive results, micro-chemical

A small drop of the alkaloid solution (usually in a weak acid like hydrochloric acid) is placed on a glass slide. A small drop of the alkaloid solution (usually

One of the most versatile reagents; it produces distinct needles, plates, or prisms with alkaloids like Cocaine or Atropine .

The paper identifies several "general" reagents that react with a wide range of alkaloids to produce predictable crystalline structures:
