樟树花挥发性有机化合物日动态变化分析
Diurnal variation of volatile organic compounds emitted from Cinnamomum camphora flowers
摘要
Abstract
In order to make clear the diurnal variation of plant volatiles, we collected the VOCs from Cin-namomum camphora flowers using the dynamic headspace air-circulation method at 7:30, 10:00, 12:30, 15:00 and 17:30, identified the main compounds of VOCs with thermal desorption system/gas chromatography/mass spectrum (TDS-GC-MS). Results showed that C. camphora flowers emitted 51 types of VOCs, mainly as terpenoids. At 15:00, species and emission of the VOCs were highest (40 species and 8 049.5 peak area units), mainly as linalool (relative content 37.0%), epoxylinalol (127%), (Z)-ocimene (72%) and perillene(6.2%). Thus, increases in species and emissions of the VOCs from C camphora flowers at 15:00 are both visibly increased revealed a possible affinity have strong relevance for strong light and high temperature stress.
