摘要:

以包合率为指标,用羟丙基-β-环糊精(HP-β-CD)制备葡萄籽提取物(GSE)包合物,在单因素基础上,利用正交试验对包埋工艺进行优化,结果显示:最优工艺条件为HP-β-CD质量分数20%、包合温度40℃、包合时间2.0h,此时包合率为98.23%;通过傅里叶红外光谱分析(FI-IR)、场发射扫描电子显微镜(FESEM)、X射线衍射仪表征证明了包合物的形成。GSE通过包合,其稳定性明显提高,在水中的溶解度由87.91μg/mL提高到251.5μg/mL。

Abstract:

The preparation of inclusion complex of grape seed extract (GSE) with HP-β-CD was optimized by orthogonal
array design based on one-factor-at-a-time experiments. Incubation in a 20% aqueous solution of HP-β-CD at 40 ℃ for 2 h
was found optimal for the preparation of GSE inclusion complex. The interaction between HP-β-CD and GSE was analyzed
by IR spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD). The
aqueous solubility of GSE was increased to 251.5 μg/mL from 87.91 μg/mL as a result of this inclusion treatment, which
was accompanied by a remarkable improvement in its stability.
