Abstract:

Nelumbinis Plumula is a kind of medicinal and edible plant with great development potential. Single factor test and response surface test were used to screen and optimize the ultrasonic-assisted extraction process of total flavonoids from Nelumbinis Plumula by polyols, and the safety, in vitro antioxidant, antibacterial and anti-allergy activities of Nelumbinis Plumula extract were determined. Results show that under the conditions of extraction solvent 1,2-hexanediol, solvent volume fraction 87%, material-liquid ratio 3.6:100 (g:mL), and extraction time 39 min, the yield of total flavonoids is 1.80%±0.08%. At 1.2 g/L, the Nelumbinis Plumula extract has no irritation, the half maximal inhibitory concentration of DPPH radical and ABTS radical is 0.76 and 0.69 g/L, respectively, and the minimum inhibitory concentration for Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa are 0.56, 1.12 and 0.14 g/L, respectively. Moreover, the half maximal inhibitory concentration of hyaluronidase is 0.35 g/L. This study provides an easy, safe and efficient method for extracting total flavonoids from Nelumbinis Plumula, which ensures the biological activity of the extract and a high yield of total flavonoids, and provides a theoretical basis for the development of Nelumbinis Plumula.

Key words: Nelumbinis Plumula, response surface, total flavonoids, antioxidant activity, antibacterial activity, anti-allergy activity
