Agave sisalana (sisal) is known worldwide as a source of hard fibers, and Brazil is the largest producer of sisal. Nonetheless, the process of removing the fibers of the sisal leaf generates 95% waste. In this study, we applied chemical sequential steps (hydrothermal extraction, precipitation, liquid-liquid extraction, crystallization, SiO2 and Sephadex LH 20 column chromatography) to obtain pectin, mannitol, succinic acid, kaempferol and a mixture of saponins as raw chemicals from sisal biomass. The structural identification of these compounds was performed though spectrometric methods, such as Infrared (IR), Ultraviolet (UV), Mass spectrometry (MS) and Nuclear magnetic resonance (NMR). All the sisal chemicals found in this work are used by both the chemical and pharmaceutical industries as excipients or active principles in products.
剑麻（Agave sisalana）作为硬纤维的来源而闻名于世，巴西是剑麻的最大生产国。尽管如此，剑麻叶纤维提取过程会产生95%的废料。在本研究中，我们采用化学连续步骤（水热萃取、沉淀、液液萃取、结晶、SiO₂ 和葡聚糖凝胶LH 20柱色谱法）从剑麻生物质中获得果胶、甘露醇、琥珀酸、山奈酚和皂苷混合物作为原料化学品。通过光谱法，如红外（IR）、紫外（UV）、质谱（MS）和核磁共振（NMR）对这些化合物进行结构鉴定。本研究中发现的所有剑麻化学品在化学和制药行业中均用作产品中的辅料或活性成分。
