In this paper, the volatiles emitted by flowers and various parts of the flower of a rare spontaneous Italian red (peel and flesh) apple named "Pelingo", were analyzed by SPME with the aim of identifying the contribution of each one to the whole aroma profile. Linalool was the most abundant volatile of flowers: from 43.0% in the flower buds, to 17.6% in the stylus and stigma headspace. The second most represented volatile was (E,E)-α-farnesene mainly emitted by the mature flowers (32.2%). Benzenoid compounds also have been identified: benzyl-alcohol is the most representative (1.0-16.5%) in all the samples except flower buds, while benzyl acetate (5.7%) and methyl salicylate (7.7%) are mainly present in the calyx and in the mature flowers respectively but not in the flower buds. Benzenoid compounds are the attractors for pollinator, probably for this reason were not detected in the headspace of flower buds.
在本文中，采用固相微萃取法（SPME）对一种名为“佩林戈”的意大利珍稀自发红苹果（果皮和果肉）花朵及其各个部分释放的挥发性物质进行了分析，目的是确定每种挥发性物质对整体香气特征的贡献。芳樟醇是花朵中含量最丰富的挥发性物质：在花芽中占43.0%，在花柱和柱头顶空中占17.6%。含量第二高的挥发性物质是（E,E）-α-法呢烯，主要由成熟花朵释放（32.2%）。还鉴定出了苯类化合物：除花芽外，苯甲醇在所有样品中最具代表性（1.0 - 16.5%），而乙酸苄酯（5.7%）和水杨酸甲酯（7.7%）分别主要存在于花萼和成熟花朵中，但花芽顶空中未检测到。苯类化合物是传粉者的吸引物，可能正因如此，在花芽顶空中未检测到它们。
