Abstract

Abstract:

In this study, the extraction of flavonoids from Rhododendoni mariae Hance was optimized by the single factor experiments and orthogonal experiment design. The optimized parameters were obtained as follows: 2 h of presoaking of medicinal materials slices, the liquid/solid of 12:1 (ml/g), extracted 3 times and 1 h of each extraction time. The membrane separation technology was applied to purify samples based on these results. The results showed that the purity of the fraction each 46.07% through relative molecular mass 105, 5×104 and 104 filters.

Key words: Rhododendoni mariae Hance, flavonoids, membrane separation, purification
