Abstract
To determine the volatile compounds in Rhodiola sachalinensis, hydro-distillation (HD) and headspace liquid-phase micro-extraction (HS-LPME) were used to extract 75 and 68 volatiles, respectively. Geraniol (24.73%), n-octanol (15.56%), and linalool (14.51%) were the most abundant essential oils detected in the HD samples, while geraniol (24.17%) and n-octanol (15.81%) were also detected at high levels in the HS-LPME samples. The main chemical classes of the essential oils were monoterpene alcohols in both the HD and HS-LPME samples at 59.02% and 37.64%, respectively. The O-heterocyclic (8.52%) and aromatic (5.92%) compounds were more abundant in the HS-LPME samples than in the HD samples.
