摘要
[Objective] This study aimed to analyze the volatile constituents in bamboo leaves. [Method] The volatile compositions in bamboo leaves were analyzed by headspace-gas chromatography-mass spectrometry （HS-GC/MS）, and identified by searching their mass spectra in NIST database. The relative percentages of them were calculated by the GC peak areas. [Result] Fifty-three chemical constituents in bamboo leaves were separated. Among them, the main components were alcohols, ketones and aldehydes, and these compounds contained unsaturated bonds. [Con- clusion] HS-GC/MS was simple and less sample-demanding and can be used for rapid analysis of volatile constituents in bamboo leaves and provide scientific basis for further research and development of bamboo leaves.
[目的]分析测定竹叶中的挥发性成分。[方法]采用顶空-气质联用方法测定竹叶中挥发性成分,利用NIST谱库对分离得到的化合物进行结构测定,应用相对峰面积法计算化合物的相对百分含量。[结果]分离得到色谱峰53种,主要以醇类、酮类和醛类化合物为主,且这些化合物中一般含有不饱和键。[结论]应用顶空-气质联用技术能够比较全面、便捷地确定竹叶中的挥发性成分,为竹叶的进一步开发利用提供科学依据。
