This work presents a new way to prepare and isolate nanometric cellulose fibrils as extracted from Citrullus Colocynthis (Cc) seeds. The nanofibrils were then characterized using spectroscopic, thermal and morphological/structural techniques. IR-Raman spectra of cellulose fibers confirmed that the treatment they went through, effectively removed all non-cellulosic material (i.e. hemicellulose and lignin). In addition to that, TGA results indicated a good and higher thermal stability of the extracted cellulose. HPLC and ¹H NMR measurements were carried out to estimate the chemical composition of cellulose from Cc seeds. TEM confirmed the presence of nanofibers in the treated sample; XRD (WAXS-SAXS) data show that the cellulose nanofibers have a higher crystallinity. The preparation (extraction and treatment) of cellulose and cellulose nanofibers from the Cc seeds as well as their thermal, structural and morphological characterizations, were successful.

这项工作提出了一种新方法，用于制备和分离从柑桔（Citrullus Colocynthis（Cc））种子中提取的纳米纤维素原纤维。然后使用光谱学，热学和形态学/结构技术对纳米原纤维进行表征。纤维素纤维的红外拉曼光谱证实，它们经过的处理有效去除了所有非纤维素物质（即半纤维素和木质素）。除此之外，TGA结果表明提取的纤维素具有良好且更高的热稳定性。进行HPLC和¹ H NMR测量以估算Cc中纤维素的化学组成种子。TEM证实了处理后的样品中存在纳米纤维。XRD（WAXS-SAXS）数据表明，纤维素纳米纤维具有较高的结晶度。从Cc种子制备纤维素和纤维素纳米纤维的方法（提取和处理）以及其热，结构和形态学表征均获得成功。
