中亚沙棘 × 中国沙棘杂交F1代果实的主要风味物质含量分析

Analysis on Main Flavor Substances Contents of Fresh Fruits of F1 Hybrid of Hippophae turkestanica-sinensis

摘要: 双中杂交沙棘是以中亚沙棘为母本、中国沙棘为父本获得的杂种优株F1代，为了评定其果实主要风味物质含量水平，应用气质联用仪GCMS-QP2010、气相色谱仪GC-2010等，对10个优株分别测定了鲜果的呈香和呈味物质含量，发现呈香物质共10类170个，主要为酯类物质，有103个，占60.6%，其含量占到总呈香物质含量的90%以上；呈味物质中的糖类主要为葡萄糖、果糖和蔗糖，酸类主要为奎宁酸和苹果酸，糖酸比值很大，最低也在12以上，酚类物质也有一定含量。综合各指标来看，10个双中杂雌沙棘优株中，风味较好的主要为“双中杂雌沙棘01号”、“双中杂雌沙棘08号”、“双中杂雌沙棘50号”，相信这些优株会为今后以鲜食为主要用途的沙棘育种工作提供很好的物质材料。

Abstract: In order to estimate the main flavor substances contents of the fruits from the so-called Hippophae turkestanica-sinensis hybrid F1 generation, H. rhamnoides ssp. turkestanica as the female parent, Hippophae r. ssp. sinensis as the male parent, the fruits from 10 superior plants were collected to analyze the contents of aromatic substance and taste substance, with the aid of the instruments like GCMS-QP2010 and GC-2010. It showed that there were 170 kinds of aromatic substances belong to 10 categories in the fruits, among them esters contained 103 kinds (60.6%) and had more than 90% amounts of the total esters. The taste substance contained three kinds of sugars-glucose, fructose and sucrose, two kinds of acids-Quinic acid and malic acid, and a few polyphenol. The sugar acid ratios of the fruits were big, and the least was above 12. According to comprehensive evaluations of above-mentioned various factors, the good F1 generations with best flavor were “Shuang-zhongzacishaji 01” “Shuangzhongzacishaji 08” “Shuangzhongzacishaji 50”, which would be good materials for seabuckthorn breeding of fresh food purpose.
