中文摘要: 以火炙竹沥、竹沥茶等为研究对象,探究在茶叶制作过程中添加火炙竹沥对茶叶化学成分和生物活性的影响。采用气相色谱-质谱和超高效液相色谱-质谱等方法分别对竹沥、竹沥茶和足炕叶的香气(挥发性)成分和水溶性(非挥发性)成分进行检测,从竹沥茶中共检测出157 个挥发性成分和157 个非挥发性成分,与足炕叶相比,从竹沥茶中鉴定出糠醛和2-甲基吡嗪两种特征香气成分,以及乙基香兰素葡萄糖苷和甜菜碱两种特征水溶性成分。此外,竹沥茶提取液的体外生物活性的测定结果显示,竹沥茶提取液的α-葡萄糖苷酶抑制活性显著高于对照药物阿卡波糖,胆酸盐结合率显著高于对照药物考来烯胺,表明竹沥茶提取液在降血糖和降血脂等生物活性方面具有一定的潜在效果和研究价值。

Abstract:The effect of adding bamboo juice in the process of tea production on the chemical composition and their in vitro bioactivity was investigated in the present study. Volatile and non-volatile components were detected by gas chromatography-mass spectrometry and ultra-high-performance liquid chromatography-mass spectrometry,respectively.A total of 157 volatile components and 157 non-volatile components in bamboo juice tea were detected.Compared to zukangye,bamboo juice tea was found to contain two characteristic volatile components(furfural and 2-methylpyrazine)and two non-volatile components(ethyl vanillin glucoside and betaine).The in vitro biological activity testing of bamboo juice tea extract revealed significantly higher α-glucosidase inhibitory activity,compared to the control drug acarbose,and a notably higher cholate binding rate than the control drug cholestyramine.These findings suggest that bamboo juice tea extract possesses potential effect and research value in lowering blood glucose and blood lipid levels.
