High purity Offer 327-97-9Best price Chlorogenic acid

Chlorogenic acid, also known as "green glycine", "coffee tanninic acid", "coffee tannin acid", is a kind of phenylalanine compound produced by the plant in the process of aerobic respiration, is a coffee-based quine acid derivative, strong antioxidant capacity, but also has anti-HIV, anti-tumor cells, antibacterial, improve central excitability, bile, anti-teratogenic, anti-allergic and regulate the activity of cytome pigment P450 enzyme and other functions. Chlorogenic acid is mainly found in the winter and chrysanthemum plants, in duzhong leaves (2-5%), gold and silver flowers (1-5.9%), sunflower seeds (1.5-3%) and coffee beans (2-8%) and other plants have higher content. It is crystallized by needles in water, is a semi-hydrate, and becomes a hydrate-free at 110 degrees C. Melting point 208 degrees C, α D25-33.5 degrees (water, C-1), K-2.2×10-3 (27 degrees C). It has a weak sour taste and has convergence. The solubility in water is 4%, more soluble in hot water, soluble in ethanol, acetone, slightly soluble in ethyl acetate, insoluble in chloroform, ether and carbon disulfide. Boil the blue dye with the concentrated hydrochloric acid. It can make bromine water fade, boil benzoic acid with hydrogen iodide, decompose with water in 230 degrees C co-heat into phenol, and dilute hydrochloric acid co-heat decomposes into coffee acid and jinjinnaic acid, etc., room temperature and dilute alkali action only coffee acid and gold ginghamic acid. Chlorogenic acid and its isomer isochlorogenic acid and chlorogenic acid are also present in the fruits, leaves and other tissues of gemo-leaf plants, which are important factors in plant metabolism.
