Mayer’s Test – Procedure, Interpretation, Limitations
Mayer’s Test is a chemical test that detects alkaloids, a class of naturally occurring organic compounds that often possess basic nitrogen atoms and exhibit pharmacological activities. This test is based on forming a creamy or white precipitate when alkaloids react with Mayer’s reagent. Mayer’s reagent is a mercuric chloride (HgCl2) …
Dragendorff’s Test – Procedure, Interpretation, Limitations
Dragendorff’s Test is a chemical test that detects alkaloids, a group of naturally occurring organic compounds that often possess pharmacological activities. This test relies on forming orange-red or brown precipitates when certain alkaloids react with Dragendorff’s reagent. The reagent contains bismuth subnitrate, potassium iodide, and acetic acid. Here is a …
Identification of alkaloids
Identifying alkaloids is crucial in studying these naturally occurring compounds, allowing researchers to determine their presence and classify them based on structural and chemical characteristics. Various methods and tests are employed for the identification of alkaloids. Here is a detailed note on the identification of alkaloids: 1. Physical Characteristics …
Alkaloids – Definition, Isolation, Occurrence
Alkaloids are a group of naturally occurring organic compounds, predominantly of plant origin, characterized by their basic nitrogen-containing structures. These compounds often exhibit pronounced physiological effects on humans and other animals. Alkaloids are known for their pharmacological activities, including analgesic, stimulant, sedative, and toxic properties. Common examples of alkaloids include …
