摘要
[目的]研究不同花期、不同时间段采收不同品种薰衣草对精油品质的影响。[方法]采用水蒸汽蒸馏法提取精油，使用气相色谱－质谱联用仪对精油成分进行测定分析。[结果]品种与花期对薰衣草精油品质的影响较大，采收时段对薰衣草精油品质影响较小。新薰一号精油品质最佳时期是在初花期，新薰二号精油品质最佳时期是在中花期至盛花期，新薰三号精油品质最佳时期在中花期。[结论]该研究可为不同薰衣草品种采收期的确定及今后薰衣草新品种的选育工作提供科学依据。
Abstract
Objective] The aim was to study the change of lavender essential oil composition in different cultivars, florescence and harvest time.[Method] Steam distillation was used for extraction of essential oil, and GC-MS was adopted for its component analysis.[Result]The effect of cultivar and florescence to lavender essential oil quality is larger than time.The optimal period for essential oil quality of Xinxun 1, Xinxun2, Xinxun 3 are early flowering period, middle flowering period to full-blossom period, middle flowering period respectively.[Conclu-sion] The study can provide scientific basis for determining harvest period of different lavender varieties and breeding of lavender new varieties in the future.
