Research progress in Euryale ferox:a Chinese herb / 国际药学研究杂志

ABSTRACT

The seed, coat, petiole and peduncle of Euryale ferox(belonging to Nymphaeaceae) are used as medicinal potions through solvent extraction, reflux extraction and ultrasonic extraction, and purification on macroporous resin. The quality controls are performed by near infra-red fingerprint spectrum, HPLC, X-ray diffraction Fourier spectrum, and ITS2 barcode. The nutrients of E. ferox contain large amount of amino acids, fatty acids and various microelements; medicinal ingredients are identified to be polyphenol, sesquineolignan, tocopherol, cerebroside, and cyclic dipeptide. The pharmacological effects of E. ferox extracts include antioxidant, free radical scavenging, hypoglycemic activity, decreasing urine protein, bacteriostasis and prevention of gastric mucosal injury. Treatment with E. ferox preparations for diabetes and chronic nephritis are performed in clinics. This review summarizes the study of E. ferox in recent years for further research and development.
