摘要
以提取皂苷后的穿龙薯蓣残渣为原料,分离纯化得到纤维素,经过水解制得微晶纤维素(MCC)。用化学方法测定样品中MCC的含量及其聚合度,并采用扫描电子显微镜(SEM)和X射线衍射仪(XRD)表征所制备的MCC的理化性质。实验结果表明:利用穿龙薯蓣残渣制得的样品中MCC为91.7%、聚合度为164、结晶度为77.1%、平均颗粒大小为23.21 nm,这些参数与台湾明台101QD型MCC对照品的测试结果相符合。
Microcrystalline cellulose （MCC） was obtained by the hydrolysis of cellulose in Dioscorea nipponica Makino＇s residue after dioscin was extracted. Its content and LODP were analyzed with chemical methods. The physicochemical properties of MCC of D. nipponica were studied by means of scanning electronic microscopy （SEM） and X-ray diffraction. The results snowed that in the sample prepared from D. nipponica, the MCC content is 91.7 % , LODP is 164, crystallinity is 77.1% and average grain size is 23.21 nm. All of these parameters are corresponded with the results of 101QD microcrystalline cellulose provided by Mingtai Co. in Taiwan.
