Complexation-responsive monoolein cubic phase containing extract of Bambusae Caulis in Taeniam

초록

Monoolein (MO) cubic phase (CP) containing Bambusae Caulis in Taeniam extract (BCT), hydrophobically modified alginate (HmAlg), and hydrophobically modified gelatin (HmGel) was prepared by a melt and hydration method. On the TEM micrographs of CP, water channels and MO bilayers were found. The phase transition temperature of MO CP was about 65.3 degrees C and it deceased by the inclusion of the additives. The release of 4-hydroxybenzaldehyde from CP was markedly suppressed at pH 4.5 but not at pH 5.5 and pH 7.4. The complex coacervate of HmGel and HmAlg was thought to suppress the release in the acidic condition.
