Extraction of Porphyran from Porphyra yezoensis for Gel Formulation Preparation

Abstract:

Porphyran, which structure is similar with carrageenan and agarose, has application potential in drug form developmentas a new pharmaceutical material. Orthogonal experiment was employed to optimizethe porphyran extraction conditions from porphyra yezoensis. The extraction temperature, pH, ratio of liquid to raw material and extraction time were confirmed as 90°C, 11, 30:1 and 3h, respectively.The polysaccharide structure detected by IR spectra was consistent with porphyran, which was suitable for gel formulation preparation.
