- 1. Phytochemistry is the branch of chemistry that deals with the study of plant-derived natural compounds, including their structure, properties, and biological activities. This field focuses on identifying and characterizing the various chemical components present in plants, such as alkaloids, flavonoids, terpenoids, and phenolic compounds. Phytochemistry plays a crucial role in understanding the chemical basis of plant properties, including their medicinal, nutritional, and ecological significance. By investigating the bioactive compounds in plants, phytochemists contribute to the discovery of new drugs, dietary supplements, and natural products with potential health benefits. The study of phytochemistry provides valuable insights into the complex chemistry of plant metabolism and its implications for human health and the environment.
