Abstract
Two new headspace methods for the analysis of isoprene emission from detach ed plant leaves are described. The first method is based on the UV-absorpti on of isoprene emitted by leaves inside quartz cuvettes and can be used for the quantitative spectrophotometric determination of isoprene production. The second technique is a micro-extraction method of isoprene from the cuve tte air for GC analysis, and is very suitable for the determination of isot ope-labeled isoprene by GC-MS.
