研究了柚子不同部位在体内自发释放的挥发物。采用固相微萃取法（SPME）在该植物的整个营养循环过程中采集，并采用气相色谱-质谱法（GC-MS）对其进行鉴定，以验证其参与昆虫传粉，这是该物种生物学中一个有争议的话题。此外，研究了通过表达未成熟和成熟果实的果皮获得的精油。共鉴定出127种化合物，占总挥发物的82.1% ~ 99.9%。主要成分为单萜类和倍半萜类，以柠檬烯（0.5 ~ 95.2%）、芳樟醇（0.2 ~ 52.5%）、杉木烯（0.5 ~ 42.5%）、月桂烯（0.2 ~ 15.4%）和对石竹烯（0.3 ~ 41.0%）为代表性成分。所有数据都进行了多元统计分析，突出了植物不同部位和不同发育阶段之间的许多差异。2009爱思唯尔有限公司版权所有。
The volatiles spontaneously emitted in vivo by different plant parts of grapefruit (Citrus paradisi Macf., Rutaceae) were collected by solid phase micro-extraction (SPME) during the whole vegetative cycle of the plant and characterised by GC-MS to verify their involvement in entomophilous pollination, a controversial topic in the biology of this species, Furthermore, the essential oils obtained by expression of the pericarp from unripe and ripe fruits were studied. Altogether 127 compounds were identified, accounting from 82.1% to 99.9% of the whole volatiles. The main constituents detected were mono- and sesquiterpenes, with limonene (0.5-95.2%), linalool (0.2-52.5%), sabinene (0.5-42.5%), myrcene (0.2-15.4%), and P-caryophyllene (0.3-41.0%) as the most represented ones.All the data were submitted to multivariate statistical analysis, highlighting many differences amongst the different plant parts and their developmental stages.
