摘要:

采用水蒸气蒸馏法提取荸荠杨梅不同生长期果实中的挥发油,气相色谱-质谱联用技术进行挥发油成分检测,并对不同生长阶段的荸荠杨梅果实的挥发油化学成分进行分析比较。结果表明,3 个不同生长阶段的样品挥发油中共检出85 个成分,其中烯类物质占主要优势(34%~48%)。不同生长期果实中含有相同的组分,且总含量最高可达40%,表明不同生长期荸荠杨梅果实挥发油的基础物质具有一定相似性,但采摘于2013年5月26日、6月6日、6月15日3 个不同时间的荸荠杨梅独有挥发油组分存在差异,尤其是最高含量组分,分别为α-石竹烯(36.9%)、绿叶白千层烯(34.2%)和π-芹子烯(31.8%)。

Abstract:

The volatile oils of Myrica rubra cv. Biqi fruits at different developmental stages were extracted by steam distillation,
and their chemical components were identified by gas chromatography-mass spectrometry (GC-MS). A total of 85 volatile
oil components were identified and quantified from fruits at three developmental stages, which were predominated by alkenes
(34%–48%). Some volatile components were detected simultaneously in the volatile oils of Myrica rubra cv. Biqi fruits from
three developmental stages, which together accounted for up to 40% of the total amount of identified compounds, indicating that
the basic volatile components of Myrica rubra cv. Biqi fruits at different stages of maturity are quite similar. However, there
were differences in unique volatile oil components, especially in the most abundant ones, which were caryophyllene (36.9%),
viridiflorene (34.2%) and selinene (31.8%) in the fruits harvested on May 26, June 6, and June 15, 2013, respectively.

Key words: Myrica rubra cv. Biqi, volatile oil, gas chromatography-mass spectrometry (GC-MS), different maturities
