The present work is concerned with the aroma of hybrids between raspberry (Rubus idaeus, L.) and arctic bramble (Rubus arcticus, L.). Analyses of the volatiles were performed in three stages. The carbonyl compounds were determined as 2,4-dinitrophenylhydrazones, the volatile acids and the neutral components separately in a combined gas chromatography-mass spectrometer components separately in a combined gas chromatograph-mass spectrometer using glass capillary columns. Over 70 compounds were identified in the aroma concentrates of the hybrids. The major components included acetic and hexanoic acids, trans 3-penten-1-ol, 2-heptanol, 3-methyl-2-buten-1-ol, benzyl alcohol and linalool. 2,5-Dimethyl-4-methoxy-2,3-dihydro-3-furanone together with alpha and beta-ionones, characteristic compounds of arctic bramble and raspberry, respectively, were found in the hybrids in much lower concentrations than in the parent berries. Percentage concentrations of the main components in the volatile oils, together with their approximate concentrations in the press juices, were determined. The contents of the corresponding compounds in arctic bramble and in raspberry are also given.
本研究关注树莓（Rubus idaeus, L.）与北极黑莓（Rubus arcticus, L.）杂交品种的香气。挥发性成分的分析分三个阶段进行。羰基化合物以2,4 - 二硝基苯腙的形式测定，挥发性酸和中性成分分别在联用气相色谱 - 质谱仪中使用玻璃毛细管柱进行测定。在杂交品种的香气浓缩物中鉴定出70多种化合物。主要成分包括乙酸和己酸、反式3 - 戊烯 - 1 - 醇、2 - 庚醇、3 - 甲基 - 2 - 丁烯 - 1 - 醇、苯甲醇和芳樟醇。在杂交品种中发现的2,5 - 二甲基 - 4 - 甲氧基 - 2,3 - 二氢 - 3 - 呋喃酮以及分别为北极黑莓和树莓特征性化合物的α和β - 紫罗兰酮，其浓度远低于亲本浆果中的浓度。测定了挥发油中主要成分的百分比浓度及其在压榨汁中的大致浓度。还给出了北极黑莓和树莓中相应化合物的含量。
