Abstract:

This research was focus on the extraction of polyphenol compounds from Dendrocalamus latiflorus shoots with
four different solvents, and the volatile compounds in polyphenol extracts were identified and quantitatively evaluated
by GC-MS. The results showed that total phenol contents in methanol, ethanol, acetone, and ethyl acetate extracts were
4.94, 4.85, 4.47 and 2.22 mg/g, respectively. Totally 24 volatile compounds were identified from the four polyphenol
extracts. Among them, the most abundant compounds were 4-hydroxybenzaldehyde, 4-hydroxybenzyl cyanide, acetic acid,
1,2,3,5-cyclohexanetetrol, 2,3-dihydro-3,5-dihydroxy-6-methyl-4-pyran and pyruvic alcohol. The major volatile phenols in
the extracts were pyrocatechol and 3-methylcatechol.
