Abstract Cymbopogon flexuous of the family Poaceae is a highly valued grass known throughout the world for its aromatic properties. The objective of the study is to identify novel myrcene and methyl iso-eugenol rich essential oil variety of lemongrass. Myrcene is an earthy, spicy, clove fragrance commonly used in the culinary and perfume industry while methyl iso-eugenol has a typical sweet-warm, spicy- clove, woody, floral odour mostly used in perfume industries. In the present study, a total of 230 lemongrass accessions were collected from different regions of North East India which were planted in Randomized Complete Block Design (RCBD) with three replications at experimental farms of CSIR-NEIST, Jorhat, during the year 2015. Morphological and essential oil quality data were recorded during the studied the year 2015-16 and 2016-17. Based on two years of selection trial data a high myrcene and methyl iso-eugenol rich essential oil line was identified and named as Jor Lab L-11. The identified line was planted along with two checked varieties at four different locations during the year 2017-18. The average essential oil yield of the Jor Lab L- 11 for the multi-location trial was 0.58 % and contained an average of 48.02 % and 39.11 % myrcene and methyl iso-eugenol respectively as major component in the essential oil. Myrcene and methyl iso-eugenol percentage, essential oil percentage, tillers/plant were significantly higher in the identified variety compared to check varieties. GC/MS data obtained from essential oil leaf Jor Lab L- 11 essential oil showed limonene, elemicin, β-pinene, citronellol, α-pinene, neryl acetate, linalool, methyl eugenol, geranyl acetate, geraniol, citral b, citronellal, citral a, α-terpineol, nerol, eucalyptol, caryophyllene oxide, 2-methylbicyclo[4.3.0]non-1(6)-ene, m-camphorene, camphor, diepi-cubenol, T-cadinol, anethole and epi-α-murulol as minor compounds.

鉴定柠檬草(Cymbopogon flexuosus L.)的新型月桂烯和甲基异丁香酚丰富精油变体(Jor Lab L-11)

摘要 禾本科(Poaceae)香茅是一种价值很高的草,以其芳香特性而闻名于世。该研究的目的是鉴定新的富含月桂烯和甲基异丁香酚的香茅精油品种。月桂烯是一种泥土、辛辣、丁香香味,常用于烹饪和香水行业,而甲基异丁香酚具有典型的甜温、辛辣丁香、木香、花香气味,主要用于香水行业。在本研究中,2015 年从印度东北部不同地区收集了总共 230 份柠檬草材料,这些材料以随机完整区组设计 (RCBD) 种植,并在 2015 年在乔哈特 CSIR-NEIST 的实验农场进行了三个重复。在 2015-16 和 2016-17 研究期间记录了精油质量数据。根据两年的选择试验数据,鉴定出富含月桂烯和甲基异丁香酚的精油系列,并将其命名为 Jor Lab L-11。在 2017-18 年间,确定的品系与两个检查品种一起在四个不同的地点种植。用于多地点试验的 Jor Lab L-11 的平均精油产量为 0.58%,并且分别含有平均 48.02% 和 39.11% 的月桂烯和甲基异丁香酚作为精油中的主要成分。与对照品种相比,鉴定品种的月桂烯和甲基异丁香酚百分比、精油百分比、分蘖/植物显着更高。从精油叶 Jor Lab L-11 精油获得的 GC/MS 数据显示柠檬烯、榄香素、β-蒎烯、香茅醇、α-蒎烯、醋酸橙花酯、芳樟醇、甲基丁香酚、醋酸香叶酯、香叶醇、
