Rosin CAS#8050-09-7
Rosin has many excellent properties due to its structural characteristics, such as anti-corrosion, moisture-proof, insulation, bonding, emulsification, etc., so it is widely used in materials, chemistry, chemical industry, electronics industry, medicine and pesticides.
Rosin CAS#8050-09-7
Rosin is mainly extracted from the secretions of pine trees, which is a kind of natural resin which is extremely rich in nature and is also a renewable resource. The composition of rosin varies slightly with the origin of raw materials and processing methods, mainly composed of a mixture of resin acid and a small amount of neutral substances, of which resin acid is the main component, accounting for more than 90% of its total. Resinous acid is the general name of a class of isomers with the molecular formula C19H29COOH, which can be divided into conjugated double-bonded (abietic acid) resinous acid, non-conjugated double-bonded (imaric acid) resinous acid, dehydrogenated (dehydrogenated) and hydrogenated resinous acid.

Puerarin, also known as pueraria flavonoids, is a kind of flavonoid glycoside extracted from the roots of Pueraria alba or Pueraria thomsonii and is also one of the main effective ingredients of Pueraria lobata. That Pueraria lobate was used to treat diseases has already been recorded in China??s ancient medical books such as Shen Nong??s Materia Medica, Treatise on Miscellaneous Diseases and Medical Dictionary.
Kanzu root is widely distributed in our country and of rich resources. It has been reported that puerarin could be extracted from Pueraria lobata (Wild.) Ohwi, Radix Pueraria thomsonii, Pueraria omeiensiswanget Tang, Pueraria edulis Pamp and Pueraria phaseoloides, but the content of puerarin differs.
Pueraria has a great value for nutrition and medicine and was considered the south ginseng of China. Puerarin has been widespread concerned over our country for its use of food and medicine in recent years.
