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
