This document contains a list of questions about alkaloids for a question bank. The questions cover topics such as defining and classifying alkaloids, extraction of alkaloids, diagnostic characters of specific alkaloid-containing plants, active constituents and uses of various alkaloids, powder microscopical examination, identification tests, classification based on chemical structure, and comparisons of certain alkaloids.
