Abstract: As one of the most common greenery vegetations in Beijing, Sorbaria kirilowii was investigated on its natural volatiles without damaged from the living plant. Such substances of volatiles were collected by high adsorptive Tenax GR by a portable circular system for lab TCT GC / MS analysis, which could determine most of the sampled chemicals. Variations of components in different seasons were found in the plant volatiles. The test on health volunteers inhaling such volatiles was observed that the trend of human mood changed into anxiety and tension, according to brain wave data simultaneously. Thus much attentions should be paid to the green olfactory environment design of forestry ergonomics with strictly use of Sorbaria kirilowii.
