Chemotypic Comparison of AFLP Analyzed Indian Peppermint Germplasm to Selected Peppermint Oils of Other Countries

摘要

Essential oil components of 20 Indian peppermint accessions were analyzed through GC and GC/MS and compared with the reported components found in oil samples of different countries (22 locations of 19 countries) to check the commercial potential of the germplasm collection.The comparative oil component analyses revealed the close relation of P4 and P5 (Indian collections) with Chinese and P9 to Japanese peppermint.Some of the analyzed samples (P6,P8,P11 and P17) were close to American,Canadian,European and South African oils.Essential oil profiles of Indian accessions P10,P14,P19 and P20 were quite different from others as revealed by component plot analysis.In addition to the similarities,distinct chemotypes in the germplasm were detected with unique essential oil component profiles,which have been discussed in details in this investigation.Further,Amplified fragment length polymorphism (AFLP) analysis of these 20 Indian accessions differentiated them genetically with a diversity ranging between 17-95%.
