Plant extracts represent a cornerstone of modern phytochemistry and product development, necessitating a clear and systematic classification. These classifications are typically based on the extraction method, chemical composition, and physical state of the final product. For instance, extracts are broadly categorized as liquid (tinctures, fluid extracts), semi-solid (soft extracts), or solid (dry powders). Further classification hinges on their dominant phytochemical groups, such as alkaloidal extracts like vinca alkaloids, or flavonoid-rich extracts like those from Ginkgo biloba. This structured approach is crucial for standardizing research, ensuring quality control in manufacturing, and facilitating precise communication across scientific and industrial fields.
