Study Notes
Alkaloid Extraction
- Methods for alkaloid extraction include percolation, maceration, and Soxhlet extraction
- Another technique for alkaloid extraction is the use of chromatography
Plant Toxicity
- Factors that affect the degree of plant toxicity include the part of the plant used, the method of preparation, the dosage, and the individual's sensitivity
- The factor that does not affect the degree of plant toxicity is the plant's color
Alkaloids in Plants
- Chemical compounds commonly found in poisonous plants in Egypt include pyrrolizidine alkaloids and tropane alkaloids
- The family of plants most common in containing alkaloids is the Solanaceae family
Detecting Alkaloids
- Tests used to detect alkaloids include Mayer's test, Dragendorff's test, and Wagner's test
- The substance used to detect alkaloids is Dragendorff's reagent
Toxicity Caused by Plants
- Causes of toxicity with poisonous plants include the ingestion of large quantities, allergic reactions, and the interaction with other medications
- Inadequate preparation or incorrect identification of plants can also lead to toxicity
