| 英文摘要 | A direct quantitative method is presented that is based upon the use of multiple headspace solid phase microextraction (hs-spme) to monitor biogenic volatile organic compounds (bvocs) released from a living leaf of pelargonium hortorum in situ. seventeen bvocs were detected by gc-ms after a single spme extraction using a car/dvb/pdms fibre. an internal standard was employed to determine the absolute amounts of seven terpenoid compounds released from a p. hortorum leaf. the quantitative analysis was performed over two days, with extraction preformed for 20 min every 3 h. the amount of volatiles extracted varied with the time of day, with two maxima recorded at 14:00 (day 1) and 17:00 (day 2), corresponding to 236 and 277 ng of the seven terpenoids recorded, respectively. these results indicate that multiple hs-spme in combination with an internal standard is a simple, quick, and quantitative technique for analysising bvoc emissions from a live plant sample. |
