There is no explanation for the question asked by the landlord upstairs! I just found Baidu knowledge and copied it indiscriminately. As a biology student, I should be able to explain your question clearly. .

Let me answer them one by one. First of all, it is not a hidden substance, but an alkaloid. It was originally extracted from colchicine in Liliaceae, so it was named colchicine. In the early 1920s and 1930s, people found that ordinary substances were found by kneading, filtering, purifying and analyzing, but the process was not as simple as extracting salt. As for why colchicine is extracted? There is something wrong with your question. You know, biology is a subject based on experiments, so many plants are used for experiments. It can be said that this substance was obtained by accident, but it was found to have magical effects. Before Mendel did the hybridization experiment with peas, he used many plant experiments, and in the process, he found many discoveries that were not directly related to the hybridization theory. This is the charm of science.
