| titleOfInvention | A method for simultaneous detection of rosmarinic acid and ursolic acid in Prunella vulgaris based on ultra-high performance liquid chromatography |
| abstract | The invention discloses an ultra-high performance liquid chromatography analysis method for simultaneously detecting rosmarinic acid and ursolic acid in Prunella vulgaris. Prunella vulgaris is a "dual-purpose" substance. As a food, Prunella vulgaris is eaten in the form of vegetables, soups, herbal teas, etc., and is favored by consumers. Anti-virus, anti-tumor, inhibit pancreatic lipase activity and other effects. However, there have been reports of adverse reactions of Prunella vulgaris in recent years, and the safety has received attention. Studies have shown that the content of rosmarinic acid in phenolic acids and ursolic acid in terpenes in Prunella vulgaris directly affects the quality of Prunella vulgaris. The invention adopts PSA adsorbent to purify the extract of Prunella vulgaris, combined with ultra-high performance liquid chromatography analysis technology, and provides a new analytical method for simultaneously detecting rosmarinic acid and ursolic acid in Prunella vulgaris, and the detection limits of the instruments are respectively It is 0.02 mg/L and 0.14 mg/L, which is of great practical significance to ensure the quality and safety of Prunella vulgaris. |
