ABSTRACT Productivity and essential oil composition of rosemary (Rosmarinus officinalis L.) were evaluated under the subtropical region of north India. The crop was planted in mid-November and harvested at six different stages. The crop harvested at 225 days after transplanting yielded 88.03 L ha−1 essential oil which was at par with the yield obtained at 210 days (83.34 L ha−1). The essential oils extracted from whole aerial parts and leaves were analysed using gas chromatography–flame ionization detector and gas chromatography–mass spectrometry techniques. A total of 30 constituents, representing 96.2–98.2% of the total oil composition were identified. Major constituents of the oil were camphor (23.9–35.8%), 1,8-cineole (18.0–23.9%), α-pinene (4.5–14.4%), verbenone (6.5–12.4%), camphene (2.5–6.9%), limonene (2.1–2.8%), bornyl acetate (1.1–4.1%), α-terpineol (1.9–3.6%) and β-pinene (2.1–3.3%). In conclusion, cultivation of rosemary as a seasonal crop can produce good-quality essential oil in the subtropical region of north India.

印度北部亚热带地区不同生长阶段收获的迷迭香(Rosmarinus officinalis L.)的生产力和精油成分
摘要 在印度北部亚热带地区对迷迭香 (Rosmarinus officinalis L.) 的生产力和精油成分进行了评估。该作物于 11 月中旬播种,并在六个不同阶段收获。移栽后 225 天收获的作物产量为 88.03 L ha-1 精油,与 210 天(83.34 L ha-1)的产量相当。使用气相色谱-火焰电离检测器和气相色谱-质谱技术分析从整个地上部分和叶子中提取的精油。共确定了 30 种成分,占总油成分的 96.2-98.2%。该油的主要成分是樟脑 (23.9–35.8%)、1,8-桉树脑 (18.0–23.9%)、α-蒎烯 (4.5–14.4%)、马鞭草酮 (6.5–12.4%)、莰烯 (2.5–6.9%) ), 柠檬烯 (2.1–2.8%), 醋酸冰片 (1.1–4.1%), α-萜品醇 (1.9–3.6%) 和 β-蒎烯 (2.1–3.3%)。总之,迷迭香作为季节性作物的种植可以在印度北部的亚热带地区生产优质的精油。
