Valeriana jatamansi Jones germplasm collected from sub-temperate Himalayan region of Uttarakhand and North-East state of Meghalaya, India was evaluated under identical conditions at National Bureau of Plant Genetic Resources, Bhowali, India, to study germplasm diversity based on essential oil composition. Twenty one compounds were identified in V. jatamansi root oil by GC and GC-MS. The major compounds identified were patchouli alcohol (0.4-63.7%), maaliol (2.9-53.8%), seychellene (4.1-27.4%), calarene/ß-gurjunene (3.0-20.8%), α-santalene (0.6-12.0%). Other compounds present were bornyl acetate (0.6-1.5%), α-guaiene (0.7-2.3%), α-bulnesene/δ-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%), ß-patchoulene (0.4-0.8%). Two superior chemotypes identified in V. jatamansi oil from Uttarakhand were: patchouli alcohol rich (IC573221, 63.7%) and maaliol rich (IC573222, 53.8%; IC589096, 51.7%), while accession from north-east was patchouli alcohol rich chemotype (IC574522, 57.2%). These superior chemotypes with higher amounts of patchouli alcohol and maaliol could be used for promoting cultivation as well as for meeting need of pharmaceutical industries.
从印度北阿坎德邦的亚热带喜马拉雅地区和梅加拉亚邦东北部采集的缬草种质，在印度博瓦利的国家植物遗传资源局相同条件下进行评估，以研究基于精油成分的种质多样性。通过气相色谱（GC）和气相色谱 - 质谱联用（GC - MS）在缬草根油中鉴定出21种化合物。鉴定出的主要化合物有广藿香醇（0.4 - 63.7%）、马兜铃烯醇（2.9 - 53.8%）、塞舌尔烯（4.1 - 27.4%）、卡拉烯/β-古芸烯（3.0 - 20.8%）、α-檀香烯（0.6 - 12.0%）。其他存在的化合物有乙酸龙脑酯（0.6 - 1.5%）、α-愈创木烯（0.7 - 2.3%）、α-布藜烯/δ-愈创木烯（0.7 - 6.3%）、7-表-α-芹子烯（0.4 - 1.4%）、克萨烷（2.1 - 3.3%）、匙叶桉油烯醇（0.7 - 3.4%）、绿花白千层醇（0.9 - 7.1%）、α-广藿香烯（0.8 - 6.6%）、β-广藿香烯（0.4 - 0.8%）。在北阿坎德邦的缬草油中鉴定出的两种优良化学型为：富含广藿香醇型（IC573221，63.7%）和富含马兜铃烯醇型（IC573222，53.8%；IC589096，51.7%），而来自东北部的种质是富含广藿香醇化学型（IC574522，57.2%）。这些含有较高含量广藿香醇和马兜铃烯醇的优良化学型可用于促进种植以及满足制药行业的需求。
