LAUSR

Phoebe sheareri Gamble is a tall tree belonging to the genus Phoebe Nees of the Lauraceae family, distributed mainly in Jiangsu, Anhui, Zhejiang, Jiangxi, Fujian, Sichuan, and Guangdong Provinces [1]. The current research at home and abroad cover P. sheareri seedling growth and free radical scavenging activities [2–4], leaf traits, biomass allocation, etc. [5]. In this study, the chemical constituents of the essential oil from P. sheareri and their contents were compared and analyzed in order to provide a theoretical foundation for the reasonable development of P. sheareri. To the best of our knowledge, a detailed analysis of the essential oil extracted from P. sheareri is being reported for the first time as a short communication. The GC-MS spectra were analyzed via a computer-based automatic search, an automated and manual analyses of a mass spectral library (NIST), and a literature search to identify each component. Finally, the relative contents of each constituent were calculated using the peak area normalization method. Fifty-two constituents were isolated from the sample, of which 34 were identified. Table 1 shows the analysis results.
