Rosemarinic acid has demonstrated its important applications in pharmaceutical, food and cosmetic fields.
Rosemarinic acid is a water-soluble substance, low content of rosemary source of light yellow to brown powder, high content of white powder; easy to absorb moisture; with rosemary special herbal odor; melting point: 171 ° C ~ 175 ° C, when ferric chloride - potassium ferricyanide solution shows blue-green.
Stability: rosemarinic acid has good stability. Salt and sucrose have no effect on the stability of rosmarinic acid; pH and temperature have less effect on the stability of rosmarinic acid, and the result shows that rosmarinic acid is more suitable to be preserved and used in acidic and low-temperature conditions; light has a greater effect on rosmarinic acid, so it should be avoided as much as possible when used.
