Phytochemical Taxonomy

chemical taxonomy studies information on the chemical composition of plants, especially at the level of biometrics, evaluates the relationship between plant species, and establishes a chemical classification system based on chemical information. The taxonomics of plant chemistryis a discipline that uses chemical characteristics to study the kinship between various groups of plants, to explore the evolutionary law of plants, and also to study plant classification and systematic evolution from the molecular level. The main research tasks of phytochemical taxonomy are to explore the characteristics and synthesis paths of chemical components contained in the classification gradessuch as gate, outline, eye, section, genus and species), to explore and study the distribution law of each chemical composition in plant systems and the characteristics of plant chemistry on the basis of classical taxonomy, and to further study the systematic development of plants in combination with other relevant disciplines. Forbeetis a class of plant pigments that are distributed only in the Central Seedand are mutually exclusive to the distribution of colored slugs. The objectives include Shang Luke, Zi Jasmine, Sumi Grass, Pan Apricot, Cactus, Ma Tooth, Lok Kwai, Shizhu, Quinoa, Quinoa, Hedgehog, and Hedgehog. From the morphological point of view, stone bamboo and millet grass belong to the central seed species, but they do not contain beet pull and therefore contain colored palladium, so plant taxonomists think that stone bamboo and millet grass should be separated, another stone bamboo.。 For example,ginseng plants can be divided into two groups: the first group, the root stem is short and usually upright, with carrot-like meat roots; It is an ancient group of ginseng genus, such as ginseng

The second group, the root stem is long and radon, the meat root is often underdeveloped or non-developed, the seeds are small, in the chemical composition, containing triamcinolone elements mainly in the zircone-type five-ring triamcinolone, in the geographical distribution of the distribution of a wide and continuous characteristics. It is an evolutionary group of ginseng genus that represents plants such as ginger three or seven
