摘　　要：了解植物细胞壁中木质素的提取、分离和结构鉴定是植物纤维化学课程教学的重要部分。本文以竹青、竹黄木质素的提取与表征作为“植物纤维化学”课程教学的一部分,重点加上学生对木质素结构表征的理解。首先,竹青、竹黄中的木质素进行提取,利用核磁共振技术对木质素进行结构表征。在教学过程中,利用本实验可以锻炼学生制备木质素的能力,熟悉核磁仪器和软件的使用,充分认识木质素的相关结构,使学生进一步了解植物纤维化学前沿,提升学生的科学素养。A key component of the "Plant Fiber Chemistry" course is understanding the extraction, isolation, and structural characterization of lignin in plant cell walls. In this work, the structural characterization of lignin was stressed for students to understand the extraction and characterization of lignin from bamboo green and bamboo yellow, which is as part of the "Plant Fiber Chemistry" course. Specifically, lignin from bamboo green and bamboo yellow was isolated identified using NMR. This experiment will help students to understand and the preparation of lignin and familiar for the usage of NMR equipment and software, completely comprehend the structure of lignin, advance their knowledge of the cutting edge of plant fiber chemistry, and enhance their communication skills.
