对产于西藏的青甘韭就其花叶的开发利用现状进行了介绍,并对芳香物质与常规营养品质进行了测试分析。结果表明:(1)产地农牧民将青甘韭在花期采收地上部(包括叶与花)砸碎阴干处理后作为佐料食用。(2)青甘韭具有一定观赏价值,可在花镜、花坛、专题园、林下(作为地被)、假山等景观中应用。(3)青甘韭花和叶中芳香物质含量差异非常明显,在花中检测到23种芳香物质,可分为7大类;在叶中检测到8种芳香物质,可分为3大类;花和叶中共有芳香物质为丙醛、乙醚、二甲基二硫化物、二丙基二硫化物4种,除二甲基二硫化物相对含量在花和叶中比较接近外,其他3种差异巨大。VC、可溶性总糖和可溶性蛋白质含量均是花高于叶,花中含量分别是叶中的1.4倍、2.4倍和7.4倍,且均呈极显著差异。

The development and utilization status and nutritional quality analysis of flower & leaf of Allium Przewalskianum Regel

The development and utilization of flower and leaf of A. przewalskianum R. from Tibet were introduced , and the aromatic substances and conventional nutritional quality were tested and analyzed. The results show that, (1)The origin of farmers and herdsmen will A. przewalskianum R. harvest in flowering shoots (leaf and flower) smashed after dried processing edible condiment. (2) A. przewalskianum R. has certain ornamental value, the flower in the mirror, flower beds, thematic park, forest as being used, rockery landscape. (1)the difference of the content of aromatic substances in flowers and leaves is very obvious, to 23 kinds of aromatic substances in flower detection, can be divided into 7 categories; 8 kinds of aromatic substances detected in leaf which can be divided into 3 categories. There are 4 kinds of fragrant substances in flowers and leaves are propionaldehyde, ethyl ether, two methyl two sulfide, two propyl two sulfide. The relative content of two methyl sulfide in flowers and leaves are relatively close, but the other 3 huge difference. The content of Vc, total soluble sugar and soluble protein were flowers was higher than that in the leaves, flowers are content in leaves of 1.4,2.4 and 7.4 times, and there was significant difference.
