Changes of Aroma Components in Oncidium Sharry Baby in Different Florescence and Flower Parts
摘要
Abstract
[Objective] The aim of this experiment was to analyze the changes of aroma components in Oncidium Sharry Baby in different florescence and flower parts, and provide refernce for finding out the formation and release mechanism of Oncidium.[Method] Aroma components in different florescence and flower parts were analyzed by solid phase micro-extraction and GC/MS technology. Volatile changes were also studied. [Result] There were 7 components identified at bud stage, 22 at first flowering stage, 24 at flowering stage and 41 at declining period. With the flower blooming and senescence, the contents of alkenes, alcohol and esters raised, and the contents of aldehydes and ketones, and alkanes decreased. There were 97 components identified in gynandrium, 71 in leans petal and 89 in labellum. In gynandrium and leans petal, the relative content of alcohol compounds was the highest, 25.36％ and 58.16％, respectively. In labellum, the relative content of alkenes compounds was 49.17％, which was the highest. [ Conclusion ] On the basis of above organoleptic evaluation and GC/MS results, alkenes is the most important compounds for Onc. Sharry Baby volatile. 3,7-dimethyl-1,3,6-Octatriene, (E)-2-Butenoic acid-2-(methylenecyclopropyl)prop-2-yl ester,3,7-dimethyl-l,6- Octadien-3-ol and (Z)-3,7-dimethyl-2,6-Octadien-l-ol are the characteristic constituents of aroma. Labellum is probably the most important part that could influence the volatile releasing.关键词
