VOLATILE COMPOUNDS FROM FLOWERS OF 6 SPECIES IN THE FAMILY APIACEAE -BOUQUETS FOR DIFFERENT POLLINATORS

Volatile compounds from flowers, buds and leaves of Aegopodium podagra ria, Anthriscus sylvestris, Carum carvi, Heracleum sibiricum, Laserpit ium latifolium and Pastinaca sativa were collected on PorapakQ and Ten axGC and identified by GC-MS. The enantiomeric compositions of the mai n chiral monoterpenes were determined by multidimensional gas chromato graphy. The characteristics of the floral fragrances were found to ori ginate in differences in the proportions of the monoterpene hydrocarbo ns, among which alpha-pinene, beta-pinene, cis-beta-ocimene, trans-bet a-ocimene, limonene, sabinene and myrcene dominated. Heracleum sibiric um and P. sativa had very similar fragrances. Pure(+)-3-carene was fou nd in H. sibiricum and C. carvi, and (-)-sabinene was the main compoun d in L. latifolium and A. sylvestris. Nitrogenous compounds, some alip hatic short-chain esters and linalool were found exclusively in the fl ower scents. The possible biological functions of the volatile compoun ds are discussed.
