摘要: 为了研究不同采收时期无患子叶片的品质差异,确定合适的无患子叶片采收时间,分别在贵州独山县和贵州省林科院实验苗圃采集清明节前(3.15)和清明节后(4.07)的无患子新鲜叶片,50 ℃烘箱中烘干至恒重,测定叶片水分、水浸出物、总灰分、游离氨基酸总量、茶多酚等主要成分成分,并对不同时期茶叶的主要成分进行比较分析,结果表明:无患子叶片中水分平均含量为6.65%,水浸出物平均含量为39.26%,游离氨基酸平均总量达到6.30%,总灰分比较大为9.36%,咖啡碱和茶多酚含量分别为0.048%和5.28%。在不同采收时期,无患子叶片品质指标存在差异,有些指标差异显著,通过隶属函数方法评价各个无患子样品,无论是贵州独山县还是贵州省林科院实验苗圃,清明节前采收的无患子叶片制茶叶效果都优于清明节后采集的叶片,在贵州省林科院实验苗圃所得的无患子样品质量最好,无患子叶片的水浸出物、游离氨基酸等主要成分含量均与质量较好的茶叶相当,具有一定的开发价值。通过比较无患子主要成分差异,并对其进行评价,确定最佳的叶片采收时期,为该地区无患子的开发利用提供数据支持。

Abstract: In order to study the differences in the quality of Sapindus mukorossi leaves which collected in different time,and make sure the best harvest time.The leaves were collected in Dushan,Guizhou on March 15 and in the nursery lands of Guizhou Academy of Forestry,Guizhou on April 5.The contents of Sapindus mukorossi water,water extracts,total ash,polyphenolic constituents,free amino acids and caffeine were determined and analyzed,the average content of water was 6.65%,water extracts was 39.26%,free amino acids was 6.30%,total ash was 9.36%,caffeine was 0.048% and polyphenolic constituents was 5.28%.There were some difference in leaves quality that collected in different time.To evaluate the Sapindus mukorossi leaves by membership function,the leaves that collected before Qingming festival had better quality than that collected after Qingming festival,no matter where the leaves come from.Compared the contents with other tea,the water extracts,amino acids were closed to the good tea.The best collected time was determined by compared and analyzed,it can provide some data for developing Sapindus mukorossi.
