4个桂花品种开花进程释放VOCs动态变化分析
Changes of volatile organic compounds released during flowering in four Osmanthus fragrans cultivar groups
摘要
Abstract
To reveal dynamic changes of the volatile organic compounds (VOCs) released in the flowering pro-cess of Osmanthus fragrans, the composition and content of flower VOCs in the four groups of cultivars (Lutens graup, Albus group, Aurantiacus group and Asiaticus group ) were analyzed under near-natural conditions using the dynamic headspace air-circulation method and the thermal desorption system/gas chromatography/mass spectrometer (TDS-GC-MS) technique. Results of the four groups listed in descending order towards VOCs re-lease were as follows:Asiaticus group(1704.56)>Albus group(1675.26)>Luteus group(1383.48)>Auran-tiacus group (1062.76). The VOCs release of four groups had single-peak-curves. During the full bloom stage, the Aurantiacus group of cultivar released the most kinds of VOCs. More than 63% of the VOCs in the four groups was terpene, and the left contained hydrocarbons, aldehydes, alcohols, ketones, esters, and aromatic compounds. Major VOCs in each group of cultivar were as follows: mostly β-ionone and terpineol in Luteus group; mainly β-ionone and linalool in Albus group; mostly β-pinene and acetate-3-hexen-1-ol in Aurantiacus group;and mostly terpineol andβ-ionone in Asiaticus groups.
