Essential oil composition of valeriana jatamansi jones from himalayan regions of India.

摘要: Valeriana jatamansi Jones germplasm collected from sub-temperate Himalayan region of Uttarakhand and North-East state Meghalaya, India was evaluated under identical conditions at National Bureau Plant Genetic Resources, Bhowali, India, to study diversity based on essential oil composition. Twenty one compounds were identified in V. root by GC GC-MS. The major patchouli alcohol (0.4-63.7%), maaliol (2.9-53.8%), seychellene (4.1-27.4%), calarene/ί-gurjunene (3.0-20.8%), α-santalene (0.6-12.0%). Other present bornyl acetate (0.6-1.5%), α-guaiene (0.7-2.3%), α-bulnesene/d-guaiene (0.7-6.3%), 7-epi-α-selinene (0.4-1.4%), kessane (2.1-3.3%), spathulenol (0.7-3.4%), viridiflorol (0.9-7.1%), α-patchoulene (0.8-6.6%), ί-patchoulene (0.4-0.8%). Two superior chemotypes were: rich (IC573221, 63.7%) (IC573222, 53.8%; IC589096, 51.7%), while accession north-east chemotype (IC574522, 57.2%). These with higher amounts could be used for promoting cultivation as well meeting need pharmaceutical industries.
