Abstract

The clonal populations of Pandanus amaryllifolius Roxb. from the western and eastern coastal regions of India were screened for 2-acetyl-1-pyrroline (2AP) and other volatile contents by HS-SPME/GC-FID. The analyses revealed that irrespective of locality, 19 volatile compounds were always detected in all population. 2AP, nonanal, phytol, 2-hexenal, 2,6-nonadienal and hexanal were found to be the major contributors. The Palghar locality from Maharashtra state was found to harbour the highest amount of 2AP (12.25 ppm), nonanal (2.97 ppm) and 2-hexenal (25.70 ppm). Phytol, 2,6-nonadienal and hexanal were highest in the Alibag locality (13.96 ppm), Chiplun locality (6.47 ppm) of Maharashtra state and the Bailhongal locality (6.25 ppm) of Karnataka state, respectively. Minor components accounted for 39.28% of the total volatiles. Besides 2AP, Palghar locality harboured ten other volatiles in higher amounts and hence was identified as an elite clonal population for the aroma contents.
